Title
(EN) COATING SYSTEM
(FR) SYSTÈME DE REVÊTEMENT
Abstract
(EN)
A curable composition comprising a) an epoxy resin containing on average more than one epoxy group per molecule, b) as curing agent a hybrid hardener, whereby said hardener is a liquid hardener blend with a viscosity of less than 150 000 mPa.s at 25°C comprising b1) an aminic compound selected from aliphatic, cycloaliphatic, and araliphatic amines, whereby said aminic compound contains, on average per molecule, at least two reactive hydrogen atoms bound to nitrogen atoms, and b2) a polymeric phenol novolac, and wherein said novolac is used in an amount of from 46 % to 62 % by weight, based on the total weight of the hardener blend b1) and b2), useful for rapid setting and protective coatings and adhesives in application fields like civil engineering, marine, architectural and maintenance.
