MAKE PVA EMULSION BASED ADHESIVE (GLUE) FOR LEATHER
What Is PVA Emulsion Based Adhesive for Leather
PVA emulsion leather adhesive is a water-based, flexible bonding glue designed for attaching natural and synthetic leather to various substrates. It offers strong adhesion, non-flammability, easy application, and excellent film-forming properties.
Meaning & Description
This adhesive uses polyvinyl acetate (PVA) as its primary polymer. It dries to a transparent, elastic film suitable for leather goods, bags, shoes, upholstery, accessories and craft materials.
Preparation of PVA Emulsion Based Adhesive for Leather
The adhesive is produced by blending PVA emulsion with plasticizers, thickeners, stabilizers, defoamers and performance additives. Water is used as the continuous phase, making the product safe and environmentally friendly.
How to Make / Making Procedure
-
Charge water into a mixing tank.
-
Add PVA emulsion under moderate stirring.
-
Incorporate plasticizer to improve flexibility.
-
Add thickener to adjust viscosity.
-
Add wetting agent and dispersing agent for better substrate penetration.
-
Add preservative, pH regulator, and defoamer.
-
Mix until a uniform, milky, stable adhesive is formed.
