WF-H5020 Hydroxyl Acrylic Resin

1. Composions

It is made up of hydroxyl acrylic resin, xylene, butyl acetate etc.

2. The characteristic

ü           Quick dry,

ü           Good sanding,

ü           High hardness

ü           The compatibility with CAB-381-0.5 is very good.

3. Application field

It forms two-component paint which cures at normal temperature by adding TDI or HDI type isocyanate composition, the compatibility with primer and topcoat is good, suitable for formulating intermediate paint and metallic paint; Mainly used in industrial coatings such as automobile repair paint, coating of locomotive, ABS plastic coating, etc.
