Epoxy systems have a natural tendency to yellow. However, careful choice of the raw materials and formulation optimisation can greatly improve the UV resistance of these systems and slow down the yellowing process tremendously.
Q-RIT 369 is a new solventfree amine adduct developed to provide enhanced UV resistance to the finished epoxy product. This curing agent can therefore be used in all kinds or applications where improved yellowing resistance or increased colour stability is suited, e.g. low yellowing floorings or decorative applications.
E-Pos 931 is a water-white cycloaliphatic epoxy resin with superior UV resistance. It is ideal for use in solventfree varnishes or in light color coatings, e.g. for application on wood.
