What Is Waterborne and PVA Based Adhesive for Leather
Waterborne and PVA based leather adhesive is an eco-friendly, non-flammable, low-odor glue formulated for bonding natural and synthetic leather. It provides flexible adhesion and high film strength after drying.
Description
This adhesive uses water as the main carrier and polyvinyl acetate (PVA) as the primary binder polymer, offering strong tack, easy application and minimal VOC.
Definition
A water-dispersed PVA emulsion adhesive designed specifically for leather bonding applications.
Overview
Waterborne PVA leather adhesives are widely used in footwear, upholstery, small leather goods and general leather assembly due to their safety and strong final bond.
Preparation
The adhesive is produced by blending PVA emulsion with plasticizers, thickeners, wetting agents, antifreeze agents and preservatives under controlled mixing.
How to Prepare / Make
-
Charge water into the mixing tank.
-
Add PVA emulsion slowly with agitation.
-
Introduce additives (plasticizer, thickener, wetting agent).
-
Adjust viscosity and pH.
-
Filter and package.
Manufacturing Process
Water phase → polymer blending → additive incorporation → homogenization → filtration → packaging.
