420 Aluminum Powder will increase the hardness and
abrasion resistance of the coated surface and improve its
moisture resistance. 420 provides limited protection from
ultraviolet light in areas that will not be protected with other
coatings and can be used as a base for subsequent painting.
Cures to a metallic gray color.
Add to mixed resin/hardener at the rate of 5%-10% by volume
or 1 ½ tablespoons per 8 fl. oz. of epoxy. 36 oz. of 420 will modify up to five gallons of mixed epoxy.
