Polyvinyl Alcohol

Polyvinyl Alcohol (PVA) can be a de-characterizing agent of thermosetting resin, mainly used as a binding agent such as carbamide, formaldehyde resin and melamine, for plywood, artificial board and timber processing. When mixed with melamine-formaldehyde resin, the Polyvinyl Alcohol size paste helps in increasing the viscosity and shortens both curing and cooling time with stronger initial cohesion. Uses of Polyvinyl Alcohol :

• Paper adhesive with boric acid in spiral tube winding and solid board production
• Thickener, modifier, in polyvinyl acetate glues
• Textile sizing agent
• Paper coatings, release liner
