Important Methyl Ethyl Ketone Peroxide (MEKP) Safety Information

Important Methyl Ethyl Ketone Peroxide (MEKP)

Safety Information

MEKP is among the more hazardous materials found in commercial channels. Proper handling of the “unstable

(reactive)” chemicals presents a definite challenge to the plastics industry. The highly reactive property which makes MEKP valuable to the plastics industry in producing the curing reaction of polyester resins and gel-coats also produces the hazards which require great care and caution in its storage, transportation, handling, processing and disposal.

Workers must be thoroughly informed of the hazards that may result from improper handling of MEKP, especially in regards to contamination and heat. They must be thoroughly instructed regarding the proper action to be taken in the storage, use and disposal of MEKP and other hazardous materials used in the laminating operation.

Current catalysts are premixed and do not require any diluents. Graco strongly recommends that diluents not be used. Diluents add to the possibility of contaminates entering the catalyst system. Never dilute MEKP with acetone or any solvent since this can produce an extremely shock-sensitive compound which can explode.

Use only original equipment or equivalent parts from Graco in the catalyst system (i.e.: hoses, fittings, etc.) because a hazardous chemical reaction may result between substituted parts and MEKP.

To prevent contact with MEKP, appropriate personal protective equipment, including chemically impermeable gloves, boots, aprons and goggles are required for everyone in the work area.

MEKP is flammable and potentially explosive, as well as potentially damaging to the eyes and skin.

Read material manufacturer’s warnings and material MSDS to know specific hazards and precautions related to MEKP.

Contaminated MEKP can become explosive. Prevent contamination of MEKP with other materials, which includes, but is not limited to polyester overspray, polymerization accelerators and promoters, and non-stainless metals. Even small amounts of contaminates can make MEKP explosive. This reaction may start slowly, and gradually build-up heat, which can accelerate until fire or an explosion result.

This process can take from seconds to days.

Heat applied to MEKP, or heat build-up from contamination reactions can cause it to reach what is called its Self-Accelerating Decomposition Temperature (SADT), which can cause fire or explosion. Spills should be promptly removed, so no residues remain.

Spillage can heat up to the point of self-ignition. Dispose in accordance with manufacture’s recommendation.

Store MEKP in a cool, dry and well-ventilated area in the original containers away from direct sunlight and away from other chemicals. It is strongly recommended that the storage temperature remain below

86° F (30° C). Heat will increase the potential for explosive decomposition. Refer to NFPA 432. Keep

MEKP away from heat, sparks and open flames.

Important Methyl Ethyl Ketone Peroxide (MEKP) Safety Information

Polyester Resins and Gel-Coats

Spraying materials containing polyester resin and gel-coats creates potentially harmful mist, vapors and atomized particulates. Prevent inhalation by providing sufficient ventilation and the use of respirators in the work area.

Read the material manufacturer’s warnings and material MSDS to know specific hazards and precautions related to polyester resins and gel-coats.

To prevent contact with polyester resins and gel-coats, appropriate personal protective equipment, including chemically impermeable gloves, boots, aprons and goggles are required for everyone in the work area.

Spraying and Lamination Operations

Remove all accumulations of overspray, FRP sandings, etc. from the building as they occur. If this waste is allowed to build up, spillage of catalyst is more likely to start a fire.

If cleaning solvents are required, read material manufacture’s warnings and material MSDS to know specific hazards and precautions. (Graco recommends that clean-up solvents be nonflammable.)

NOTE: Graco recommends that you consult OSHA Sections 1910.94, 1910.106, 1910.107 and NFPA No. 33,

Chapter 16,17, and NFPA No. 91 for further guidance.

Theory of Operation

Theory of Operation Grounding

External Mix

The resin or gelcoat stream and the catalyst stream impinge when they exit the spray tip. The catalyst is atomized with air pressure is contained by AAC air to achieve high mix quality. External mixing reduces internal clogs from cured material.

Internal Mix

The material and catalyst pass through an internal static mixer where they mix. The mixed solution is dispensed.

Chop Guns

Fiberglass is pulled through cutter and cut into small strands. The cut strands are then dispensed into the mixed material stream.

This equipment must be grounded.

Grounding reduces the risk of static shock by providing an escape wire for electrical current due to static build up or in the event of short circuit.

NOTE: Grounding wire and clamp assembly 17440-00 is included with Graco FRP proportioner. If using a different proportioner that does not come with a grounding wire and clamp assembly, order 17440-00 or provide your own.

Ground the dispense gun through connection to a

Graco approved grounded fluid supply hose.

Check your local electrical code and related manuals for detailed grounding instructions of all equipment in the work area.

Impingement versus Airless

Spray Tips

Impingement spray tips are typically for chop guns. This utilizes multiple impinging streams to create the fan pattern.

Airless spray tips are typically for gel guns. This utilizes a single cat-eye shaped orifice to create the fan pattern.

Air Assist Containment

Operation

Operation

High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

• Do not point gun at anyone or at any part of the body.

• Do not put your hand over the dispense outlet.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Follow Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or servicing equipment.

Trigger Lock

Adjust AAC

If the spray pattern is not even, the AAC air pressure may need to be adjusted. For all guns, the AAC air pressure is set at the system. The external mix gun includes an AAC air pressure adjustment on the gun also, see

AAC reference in F IG . 7 on page 19. To increase AAC air

pressure on the external mix gun, turn knob counter-clockwise. To decrease air pressure, turn knob clockwise. For large changes in AAC air pressure, adjust the pressure at the system.

To prevent skin injection, engage the trigger lock before adjusting cutter motor.

F IG . 10

RS guns with a cutter installed have two modes of operation. When the trigger is pulled halfway, material sprays but the cutter is not activated. When the trigger is pulled all the way, the air motor in the cutter is started and glass begins dispensing.

Premature Blade Cartridge or

Anvil Wear

NOTICE

More tension between the anvil and blade cartridge leads to the anvil and blade cartridge wearing out faster. To prevent premature wear and to maximize anvil and blade cartridge life, use the minimum tension required to cut the glass and make small increases in tension when strands are not cut cor-

rectly. See Adjust Anvil to Blade Cartridge Tension , page 23.

4.

With the trigger lock engaged, rotate the cutter

motor (AH) clockwise to decrease speed. See F IG .

10. If necessary, rotate counter-clockwise to

increase speed.

5.

Do another bag check to determine the new glass output.

a.

Weigh a bag.

a.

Dispense glass into the bag for the same amount of time as in step 1b.

b.

Weigh the bag to determine glass output.

6.

If the weight does not match the baseline bag weight, adjust the cutter speed then do another bag check. Repeat until the new bag weight matches the baseline bag weight.

The two most common causes of premature anvil or blade cartridge wear are excessive tension between the anvil and blade cartridge and excessive cutter speed.

See page 23 for the Adjust Anvil to Blade Cartridge

Tension procedure.

To reduce the cutter speed while keeping the same glass output, perform the following procedure:

22 3A0232J

Operation

Anvil and Blade Cartridge

Replacement

See Replace Anvil

and Replace Blade Cartridge

pro-

cedures on pages 30 and 31.

Adjust Cutter Speed

When dispensing a material and glass mixture, the speed at which the cutter spins can be adjusted to ensure the correct ratio of glass to dispensed material.

NOTE: It may be possible to prevent premature anvil and blade cartridge wear by slowing the cutter speed

and adding an additional strand of roving. See Premature Blade Cartridge or Anvil Wear on page 22.

1.

Determine whether more or less glass is needed.

a.

Place bag over cutter chute. b.

Place bag over gun fluid outlet. Try to keep bag away from the dispense outlet to prevent piercing the bag which will lead to inaccurate dispense measurements.

c.

Dispense a 15-30 second shot.

d.

Weigh both bags and calculate ratio. e.

Determine whether more or less glass is needed. Consult material manufacturer recommendations for ratio requirements.

f.

If ratio is ok, then no adjustment is needed. Otherwise, continue with adjustment procedure.

Adjust Anvil to Blade Cartridge

Tension

NOTICE

More tension leads to the anvil and blade cartridge wearing out faster. To prevent premature wear and to maximize anvil and blade cartridge life, use the minimum tension required to cut the glass and make small increases in tension when strands are not cut correctly.

To cut the glass strands, the blade cartridge is pressed against the anvil. If the strands do not appear to be getting cut correctly an adjustment may be needed.

To adjust the tension:

1.


2.

Disengage the tension lockdown (AG) by pushing towards the front of the gun.

3.

Turn the tension knob (AF) on the cutter: counter-clockwise to increase tension, clockwise to

decrease tension. See F IG . 10.

4.

Engage tension lockdown.

If there is still excessive anvil or blade cartridge wear

after performing this procedure, see Premature Blade

Cartridge or Anvil Wear on page 22.

To prevent skin injection, engage the trigger lock before adjusting cutter motor.

3.

With the trigger lock engaged, rotate the cutter motor (AH): clockwise to decrease speed, coun-

ter-clockwise to increase speed. See F IG . 10.

4.

Go to step 1 to test ratio and repeat adjustment as necessary.

Operation

Adjust Anvil to Idler Tension

To adjust the anvil (AC) to idler (AJ) tension, the idler

position can be adjusted. See F IG . 10 on page 22.

1.

Follow Pressure Relief Procedure

, page 25.

2.


3.

Loosen knob (528) then remove cover (527). See

4.

Loosen idler cap screw (617) using 3/16 in. hex key.

5.

Slide idler to desired position.

6.

Tighten idler cap screw to lock idler in position.

Adjust Blower Air

The cutter has blower air to help keep the anvil cool and to keep the inside of the cover free of debris. The blower air has been factory set to optimize performance of the cutter, however it can be adjusted.

Use a 3/32 hex allen key to turn adjusting screw (635) counter-clockwise to allow more air flow into the inside of the cover on the cutter assembly. This will affect air motor performance as less air will go to the air motor resulting in slower cutter speeds.
