Urethane Acrylates
Productized by urethenation of isocyanate compounds, polyol compounds, and hydroxyl group-containing acrylic monomers. Have features such as toughness, extensibility, and high hardness, and are widely used in hard coats, adhesives, pressure-sensitive adhesives, etc.
About urethane acrylates
Epoxy (meth)acrylates
We have productized esters of (meth)acrylic acid and epoxy compounds.
Due to its superiority in weather resistance, chemical resistance, and bending resistance, it is widely used in painting, electricity, adhesives, composite materials, various coating materials, etc.
