MACHINABLE CERAMICS INSTRUCTIONS
310 - 914 - 960 - 915 - 56L
MACHINING TOOLS
Use only sharp cutting tools, carbide cutting tools are preferred. Check tools for sharpness frequently. Ceramics can cause rapid wear of cutting edges. Clamp work firmly to avoid vibration and chatter.
LUBRICATION
Keep a continuous stream of water on the work and tool. Insufficient lubrication will cause dulling of cutting tools and chipping of the ceramic. Lubrication is a must for precision work. Lubricants recommended include
Cimstar 40 Pink, Supercut S67 and Quaker 103.
CUTTING
Use bonded silicon carbide or diamond cut off wheel with speeds of 6000 - 8000 S.F.M.
(2000-2500 rpm). Cut down into work.
BANDSAW
Blade type continuous coat, carbide grit. Use a band speed of 100 feet per minute.
DRILLING
Use Carbide drills, Carboloy 883 or equivalent. For high speed drills, drill slower.
Never drill all the way through. Use a drill jig and drill from both sides.
Re-sharpen bits every 3 - 4 holes.
Drill Size RPM Feed - RPI Drill Size RPM Feed - RPI

MILLING
Cutting Speed (surface ft. per min.).........20 - 35
Chip Load (inches per tooth)...................0.002
Depth of Cut (inches)...............................0.150 -0.200
THREADING
Use a diamond wheel with a tool post grinder or tungsten carbide tools.
TAPPING
Use high speed steel or carbide. Drill size should allow for 70% thread form. Use lubricant.
TURNING
Use carbide tool bits or silicon carbide wheels on post grinder.
Tool Type..................................................Carboloy 883
Cutting Speed (surface ft. per min.)........30 - 50
Feed Rate (inches per revolution)...........0.002- 0.005
Depth of Cut (inches)..............................0.150- 0.250
GRINDING
Use a silicon carbide, resinoid bonded wheel at the recommended speeds. Use a soft, coarse grained wheel for heavy grinding. Use a hard, fine grained wheel for finishing.
No heat treating is required, however, shrinkage may occur in use. A test piece should be exposed to the service temp. (for the usage time) to check for shrinkage before committing to making actual parts.
NOTE: Cotronics ceramics particles are abrasive clean machines thoroughly after machining.

CERAMIC CASTING
Follow the detailed instructions on the product label. Use the specified base to activator weight ratio.
1. Using the weight ratio as specified on the product label, thoroughly mix the powder portion with its activator to form a thick paste-like consistency. For fine details 1% or 2% extra activator (by weight) can be used to increase fluidity. Working time is approximately 10 to 20 minutes.
2. Pour the ceramic mixture into the mold and work it into the corners. Overfill the mold slightly.
3. Vibrate the mold to remove air bubbles. (2-10 minutes should be sufficient).
4. After 20 minutes, remove any excess material with a trowel.
5. Cover the mold with a thin sheet of plastic and cure for 16-24 hours at room temperature.
6. After the room temperature cure, heat the ceramic casting for 2 hours at 225ºF (110ºC). This will remove any excess water and will provide additional strength.
7. A post cure at 1750ºF (950ºC) will increase the strength 2- 3 times. For parts under 1" thick heat the ceramic casting at a rate of 200ºF per hour.
8. For thick castings (over 4" thick) request a special, slow curing instruction sheet.
9. HINT: Make a trial casting in a drinking cup (as a mold) before making the actual part. A trial part 2" dia. x 1" high is ideal. Heat treat the disc to check product shrinkage and strength before making critical parts.
10. NOTE: A thick paste like consistency is recommended for optimum strength and minimum shrinkage. A thick paste will flow when vibration is applied to the mold and container.
The Ceramic Castings will not out gas after it is fully cured.

INSTRUCTIONS FOR 101 MOLD MAKING MATERIAL
REPLICAST 101 can be used to make or repair flexible parts.
1. Machine an aluminum, plastic or other suitable pattern for use as a master. The pattern should be an exact duplicate of the part you wish to make. A good surface finish is desired.
2. Prepare a suitable container approximately ½" to 1" bigger than the master on all sides.
Coat the master and its container with Replicast 101 MR Mold Release. (Petroleum jelly may be used if 101MR is not available).
4. RE-STIR Replicast 101, some settling can occur in storage. Use only metal stirring tools.
5. Carefully weigh out 100 parts of Replicast 101 Resin to 10 parts of Replicast 101 Hardener.
HINT: The component’s weight = total weight - weight of empty container.
6. Stir slowly and thoroughly, carefully scraping the side walls and bottom of the mixing container.
7. Hold the container of 101 (approximately 18" from the container holding the master) and pour the mixture in a thin stream.
8. Pouring slowly, in a thin stream, will allow the liquid rubber to de-gas and produce a void-free casting.
REMEMBER:
Mix slowly and thoroughly. (Do not whip air into mixture). Pour in a thin stream.
Do not introduce moisture into the un-mixed system.
Use REPLICAST 101 Mold Release for the best results.

CERAMIC ADHESIVE INSTRUCTIONS
INSTRUCTIONS
1.
FOR NON-POROUS MATERIALS:
1. Clean surfaces. Remove old coating, adhesive, dirt, grease, etc.
2. De-grease with solvent such as Resbond 105 RS and dry thoroughly.
POROUS MATERIALS:
1. Clean surface of loose dirt and dust.
2. Moisten the surface to be bonded with a solution of 50% ceramic thinner and 50% clear water.
(Note: Use the thinner for the specific adhesive system selected).
2. MIX ADHESIVE thoroughly prior to use, follow directions on product label. Do not whip air into the mix.
NOTE: For two component systems, mix the powder and activator according to the weight ratio on the label.
3. APPLY ADHESIVE by spatula, brush or dipping. Completely wet the surfaces.
4. IMMEDIATELY press surfaces together. If necessary clamp or fix materials to maintain uniform distance while curing. Typically a gap of 0.01” to 0.02” is recommended. Excess adhesive can be removed with a damp rag.
CURING
1.
Let joint air set 1- 4 hours.
2. Cure a minimum of 2 hours at 200ºF (90ºC).
3. Avoid excessively fast heating. It will cause adhesive to bubble and form a weak bond.
POST CURE
4. To Develop maximum strength, solvent and moisture resistance. Post cure for 1 hour at 250ºF (120ºC) followed by
1 hour at 600ºF - 70 0ºF ( 315ºC - 370ºC) .
5. NOTE: Always follow the specific recommendations shown on the product labels. Consult the product label for instructions. Bond testing with sample pieces for your specific is applications recommended. Fast curing systems may be available for your specific needs. Contact Cotronics for recommendations.
6.
POTTING APPLICATIONS: For potting applications request instructions for ceramic potting materials.
NOTE: these products will not out-gas after a complete cure.
64
EPOXY ADHESIVE INSTRUCTIONS
PREPARATION
1. Clean surfaces of all grease, oil, dirt, old coatings, rust, etc. Roughen surface to improve adhesion.
For best results use Resbond 105RS Solvent or Resbond Surface Prep 105RP.
2. Re-stir all Resins and Hardeners to insure a uniform, homogeneous product.
Warming resins to 100ºF - 120ºF (35ºC -50ºC) will reduce the viscosity and ease mixing.
MIX RATIO
3.
All measurements are by weight. Follow instructions supplied on the product label for the exact mix ratios.
NOTE: Weight = (total weight) - (weight of container)
4.
A. Weigh out the resin and the hardener into a separate clean container. Combine the resin and hardener. Mix slowly and thoroughly. Make sure to scrape the sides and walls of the container to insure a complete mix.
Do not whip air into the mix.
B. For single component systems re-mix, apply and heat cure as directed.
VACUUM DEGASSING
5.
Special additives have been incorporated into COTRONICS’ Epoxy systems to eliminate the need for vacuum degassing. Warming resin and letting the mixture stand several minutes before use will normally remove most of the remaining entrapped air. Vacuum degassing should be employed for critical applications.
NOTE: The use of warmed resin may reduce working time.
ADHESIVE APPLICATIONS
6.
Apply with a trowel or with a dispensing syringe. Use Bond Lines from 0.005” - 0.010”.
Disposable syringes are available from Cotronics.
POTTING AND CASTING APPLICATIONS
7.
Pour slowly, in a thin stream, to allow the air to escape. The material should be allowed to flow around and under the components. NOTE: A fast pour may trap air pockets.
CURING
8.
Follow the curing procedures listed on product labels for these systems.
Optimum high temperature properties are only obtained when following the recommended cure cycles.
9.
Post cure for 4 hours at 200ºF - 250ºF (90ºC -120ºC) to enhance any room temp. curing system’s properties.
CAUTION See MSDS for safety instructions. Mixing batches over 50-100 grams can create excessive heat in some systems.

HINTS AND TIPS
Mixing and Measuring Adhesives
Re-stir all products before weighing or dispensing. Carefully weigh out the resins and hardeners separately, before mixing.
(Use a minium mix of at least 25 grams to insure a homogenous mixture) Mix thoroughly and completely before using.
Improper measuring or mixing can cause materials not to cure, soft spots, air voids on the surface, sticky surfaces, softening at elevated temperatures, changes in chemical or electrical resistance.
Bonding Dissimilar Materials
Select an adhesive with a thermal expansion coefficient that closely matches the materials to be bonded. When possible select a flexible epoxy. Clean dirt, oils, greases and mechanically roughen the surfaces prior to bonding. Cure materials at room temperature and at 250ºF.
Recommended Bond Line Thickness For Adhesive Bonding
For standard epoxy and ceramic adhesives a bond line thickness of 5-8 mils (0.005-0.008) will produce excellent results. For
Cotronics' non-sag putties (epoxy or ceramic) bonds of 0.020 or more can be used. To form a thick layer or section apply putty in several layers curing between each application.
Joint Design and Bond Strength
Butt joints are usually the weakest, inserted joints ( tongue and groove, rod into a tube provide a mechanical reinforcing) are the strongest. For repair and difficult applications use a metal or ceramic cloth buried in the glue line for additional reinforcing.
Bonding to Teflon, Nylon, Polyolefin and Similar Plastics
Specific surface treatments and/or etching are required for bonding these plastics. Cotronics' offers flexible and activated epoxies that form strong adhesive bonds to many of these difficult-to-bond materials.
Preventing Flow of an Adhesive From a Joint
Select an adhesive with high viscosity or with thixotropic properties and use just enough adhesive to completely fill the gap between the two surfaces to be bonded.
Thinning Adhesives for Application
Epoxy formulations can be thinned with mild heat or epoxy thinner 105RT to ease flow, create a thinner bond line or facilitate encapsulation.
Removing Bubbles in Potting Materials
You can reduce the amount of entrapped air by warming epoxies prior to application or by vacuum degassing. (Apply pressure of 29 in Hg for 2 minutes and then release).
Working With Electrically or Thermally Conductive Adhesives
Electrically and Thermally conductive adhesives will provide optimum results after a post cure for 2 hours at 250ºF.
Electrically conductive materials are also available in flexible versions to accommodate bonding substrates with different thermal expansions.
Cracking in Ceramic Adhesives and Castable Ceramics
Cracked and weak castings, encapsulations or adhesive bonds can occur when using ceramic materials if excess activator or additional water has been added to the uncured mixtures. Check the mix ratio that was used when mixing the materials.
Accelerating Cure Time
The best way to shorten the cure cycle is to raise the temperature. Typically most systems can be quickly cured at 250ºF. One should check each products data sheet or label for specific instructions and recommendations.
Modifying Existing Formulations
Cotronics can adjust such formulations to provide variables as viscosity, gel time, curing characteristics as well as lap shear strength, peel strength, flexibility, chemical stability, heat resistance, impact strength color etc.
Special Packaging for Production Applications
Cotronics can supply materials in pre-measured units and in bulk quantities to facilitate the use of these systems in any production facility or field application. www.cotronics.com (718) 788-5533 Fax (718) 788-5538
