MIXING COMPONENTS Permacron® 1:1 Elastic Primer Surfacer 3300 PERMACRON ELASTIC HARDENER Permacron® Elastic Hardener 3301 MIX RATIO Component 3300 3301 Volume 1 1 APPLICATION VISCOSITY Approximately 17 – 21 seconds at 68°F/20°C, DIN 4 POT LIFE Approximately 8 hours at 68°F/20°C SPECIAL TIPS 1. Do not allow Permahyd® Plastic Cleaning Paste 7081 to dry on the surface of the plastic substrate. 2. Thoroughly clean and scuff all surfaces of the plastic part, paying special attention to all edges. 3. For hard to reach areas of the plastic part, use the application brush that is included with the Permahyd® Plastic Cleaning Paste 7081. 4. Permahyd® Plastic Cleaning Paste 7081 is designed for raw plastic and is not suitable for cleaning painted surfaces. 5. Always use a clean scuff pad. 6. Soft plastic may require a finer scuff pad. 7. Difficult to clean plastics may need to be cleaned more times, or if applicable the plastic may be baked for a minimum of 15 minutes at 140°F (60°C). Some OEM plastic bumpers do not recommend a bake cycle. Once the plastic has cooled, repeat the procedure below for preparing raw plastics beginning with step 2. Plastic parts repaired with Permacron® 1:1 Elastic Primer Surfacer 3300 may not be washed with a high pressure jet within six weeks of the repair. After this period, the nozzle must be held at a distance of no less than 12 inches from the object.
