Hempadur Mastic 45880 is a two-component adduct cured, high solids, high build epoxy paint. With a tough coating and good wetting properties, together with low temperature curing, Hempadur Mastic 45880 will provide a good surface finish, at lower temperatures.
Hempadur Mastic 45880 is ideal as a self primed, surface tolerant paint system or as an intermediate or finishing coat in heavy duty paint systems where low VOC and high film build are required.
For immersed areas Hempel Hempadur Mastic 45880 is only recommended for minor repairs as primer, and full applications as intermediate or topcoat. Can be specified where extended recoating properties for polyurethane topcoats are requested (typically travel coating). May be used directly on cured zinc silicate (Hempel Galvasil products) or spray metallized surfaces to minimize popping.
Shade 18600 can be used in paint systems complying with European ATEX Regulation EN 13463-1: 2001. Please also note that Shade 18600 will have a lower gloss than usual for other shades.
Hempadur Mastic 45880 should be applied on dry and clean surfaces with temperatures above dew point. It is recommended that Hempadur Mastic 45880 is applied with an airless spray.
Hempadur Mastic 45880 is a self-primed, surface tolerant paint system which can be used as an intermediate or finishing coat in heavy duty paint systems where low VOC and high film build are required.
