WL-AC309 is a hydrophilically modified aliphatic polyisocyanate
curing agent, synthesized from 1,6-hexamethylene diisocyanate
(HDI). It exhibits unlimited miscibility with hydrophilic auxiliary
solvents and must be diluted with solvents meeting polyurethane
application standards. It offers a long pot life, fast drying
speed, rapid hardness development, excellent sag resistance, and
outstanding weatherability. In addition, it significantly enhances
the physical and chemical performance of water-based coatings or
inks. The 2K PU coating formulated with WL-AC309 exhibits high
gloss, superior fullness, and anti-yellowing properties, suitable
for applications in aluminium powder paint, topcoat and varnish in
various metal substrates.
