Elvacite® 4402

Elvacite® 4402 is a hydroxyl functional methacrylate polymer that is used as a the main binder in acrylic systems that are cured with isocyanates.
Product Overview
Elvacite® 4402 is a methacrylate based resin that contains hydroxyl functionality.
This functionality allows it to be crosslinked and cured with isocyanates and amines.
Elvacite® 4402 is available as a solid bead that is soluble in toluene, ketones, and esters.
It has a low molecular weight and can therefore be used to produce solutions with high solids and a low viscosity.
Films formed from solutions containing Elvacite® 4402 have excellent outdoor durability, optimal balance of flexibility & hardness, and improved adhesion.
An added benefit of these solutions is improved pigment wetting which leads to better color strength in cured films.
Elvacite® 4402 is an ideal resin for high solid, low VOC, 2K systems.
