Production name: Phenalkamine WV2801X9
WV2801X90 is a unique type of epoxy resin hardener based on the latest modified Phenalkamine technology.It is WV2801 with 10% xylene solvent.Viscosity is lower and application property is better.
Advantages:
Excellent combination of rapid cure and long pot-life at both ambient and low temperatures（<5℃）.Curing well and good adhesion even poorly prepared surfaces.Good choice for formulating high solids coatings. Excellent chemical tolerance and superior corrosion resistance. Excellent moisture tolerant during cure.
