Epoxy / Hybrid Primers

View / Download PDF Data Sheet

This high-gloss electrostatic spray-grade epoxy powder coating is designed for use as a highly corrosion resistant, sandable primer. It should be used when added corrosion protection is needed, or when the substrate has surface imperfections that would adversely affect the quality of the ensuing topcoat. This coating should not be used as an exterior topcoat. Epoxy/Hybrid Primers are also available for use when substrate quality is less than desired or enhanced resistance to acidic or sunlit environments is needed. Primers are available in a medium-shade, neutral gray color at high gloss.

This primer was formulated to achieve maximum adhesion to a topcoat. Since topcoats supplied by other coating manufacturers may be used, we recommend evaluating adhesion of this product to whatever topcoat is chosen. This may be done by a simple crosshatch adhesion test after one hour in boiling water. No loss of adhesion should be evidenced, using Permacel (TM) tape.

Storage Stability:

The maximum storage temperature for this coating is 80°F at 50% Relative Humidity. Under these conditions, a shelf life of 12 months is expected.

Primer for Topcoats Needing:

Increased resistance to chemical attack in coastal and marine environments, to cover surface defects on extruded aluminum shapes, and for porous castings where out-gassing may cause pinholes in the ensuing topcoat. Can also be used as a corrosion resistant primer for liquid-applied coatings. Provides more corrosion resistance than Hybrid Powder primers, but less resistance to degrading in ultraviolet light.

Availability:

This product line is available to all powder coating applicators for use on any adequately pretreated substrate. If sanded for aesthetics, before topcoating, the coating surface must be adequately cleaned before application of the topcoat.

Customer Line Surveys:

Crosslink Powder Coatings can tailor these products to your coating line. To do so, our skilled associates must perform a coating line survey, to include monitoring of the oven times and temperatures. Please advise if you would like this service.

Precautions:

All dusts are respiratory irritants. The coating area must be properly ventilated and oven air exhausted to the outside environment. If skin contact occurs, immediately wash with mild, soapy water. If eye contact occurs, flush with water immediately and secure medical attention. Dust clouds of any finely divided organic material can be ignited by electrical sparks or open flames. All equipment must be electrically grounded to preclude buildup of static electricity. Dust collection equipment must be provided for adequate exhaust of dust-laden air.
