Description: HEMPADUR MASTIC 45880/45881 is a two-component polyamide adduct cured, high
solids, high build epoxy paint. It forms a hard and tough coating, has good wetting
properties and low temperature curing.
Recommended use: As a selfprimed, 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.
Multipurpose coating as per specification for maintenance including ballast tanks and
underwater hull and new steel in those cases, where a need for few products
outweighs more specialised coatings.
Can be specified where extended recoating properties for polyurethane topcoats are
requested (typically travel coating). May be used directly on cured zinc silicate
(GALVOSIL products) or spray-metallized surfaces to minimize popping.
As a topcoat where the usual outdoor cosmetic appearance of epoxy paints is
acceptable.
Service temperatures: Maximum, dry exposure only: 120°C/248°F
