promotes adhesion, and prevents solvent
attack from the topcoat.
Advantages:
• Fast drying
• Excellent adhesion to polystyrene
• Excellent adhesion to gas counter
pressure Noryl® plastics*
• Prevents crazing or attacking of the
plastic substrate by solvents in the topcoat
• No critical recoat
• Ready to spray, no reduction needed
• Free of lead and chromate hazards
• May be used as a primer for wood,
metal and other structural foam plastics.

SPECIFICATIONS
General: Substrate should be free of
grease, oil, dirt, fingerprints, drawing compounds,
any contamination, and surface
treatments to ensure optimum adhesion
and coating performance properties.
Plastic: Mold release must be removed
from the substrate. Wash the surface with
isopropyl alcohol.
Due to the diverse nature of plastic substrates,
a coating or coating system must
be tested for acceptable adhesion to the
substrate prior to use in production. Reground
and recycled plastics along with
various fire retardants, flowing agents,
mold release agents, and foaming/blowing
agents will affect coating adhesion.
Please consult your Honest-Joy
Chemical Coatings Sales Representative
for system recommendations.
Testing: Due to the wide variety of substrates,
surface preparation methods,
and application methods and environments,
the customer should test the complete
system for adhesion and compatibility
prior to full scale application.
