Item: EPI APV.500 PT Manufacturer: APV.500 A resin based additive for use in traditional one-component, half-synthetic paints and varnishes to speed up the curing process. For interior use only, e.g. on chairs, tables, etc., this product can be added up to 50% to Epifanes Clear Gloss Varnish for a harder, more scratch-resistant finish. Do not use with Epifanes Mono-urethane and Epifanes Nautiforte. If not more than 5-7% is added, through-drying time will be reduced without affecting flexibility, gloss, and longevity.
