Polyvinyl Butyral
Polyvinyl Butyral (PVB) Resin HH-PVB
♦ Appearance: Tiny, free-flowing white powder.
♦ Properties: Polyvinyl butyral (or PVB) is a thermoplastic resin synthesized by the aldol reaction of polyvinyl alcohol (PVA) and butyraldehyde. It has excellent transparency, impact resistance, water resistance, and adhesion, and is widely used in multiple fields.
♦ Application:
1.Coating adhesive ( anticorrosive/shop primer, baked enamel, wash primer, paint and coating, used for various bases);
2.Ink adhesive;
3.The whiteboard ink adhesive;
4.Textile printing and non-woven adhesive;
5.Engineering ceramic and other ceramics;
6.Organic pigment wetting agent.
