SPECIFICATIONS
General: Substrate should be free of grease,
oil, dirt, fingerprints, drawing compounds, any
contamination, and surface passivation
treatments to ensure optimum adhesion and
coating performance properties. Consult
Metal Preparation Brochure CC-T1 for
additional details.
Aluminum: If untreated, prime with Industrial
Wash Primer, P60G2, or Honest Joy® Wash
Primer, 518054.
Aluminum: A proprietary chrome phosphate
treatment is required.
Aluminum: A minimum of a 5-stage chrome
phosphate metal treatment, or equivalent, is
required for good adhesion and optimum
coating performance properties.
Primer, 518054.
Plastic: 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. A filler or
primer/barrier coat may be required. Please
consult your Honest-Joy Chemical
Coatings Sales Representative for system
recommendations.
Testing: Due to the wide variety of
substrates, surface preparation methods,
application methods, and environments, the
customer should test the complete system for
adhesion and compatibility prior to full scale
application.

Catalyst CONTAINS ISOCYANATES.
People who have chronic (long-term) lung
or breathing problems or have had a
reaction to isocyanates, must not be in the
area where this product is being applied.
Where overspray is present, a positive
pressure air-supplied respirator should be
worn. If unavailable, a properly fitted
organic vapor/particulate respirator may be
effective. Consult catalyst MSDS and
product label for complete handling
instructions.
