Composition and Compound of Waterborne and PVA Based Adhesive for Leather
Introduction
Waterborne and PVA based adhesive for leather is a flexible, low-odor, eco-friendly adhesive system designed for bonding natural leather, synthetic leather, PU leather, coated leather, and textile-backed leather materials. With strong adhesion and excellent bending resistance, waterborne and PVA based adhesive for leather is widely used in footwear, leather goods, upholstery, and industrial manufacturing.
1. What Is Waterborne and PVA Based Adhesive for Leather
Waterborne and PVA based adhesive for leather is a water-dispersed polymer adhesive formulated using PVA emulsions, tackifiers, plasticizers, and stabilizing additives. It forms a transparent, flexible film that bonds effectively to smooth and porous leather surfaces.
2. Description & Meaning
Waterborne and PVA based adhesive for leather is a non-flammable, safe-to-use adhesive that provides high initial tack, clean application, and long-term flexibility, making it ideal for delicate leather operations where solvent-based adhesives may cause damage or odor issues.
3. Purpose & Uses
Waterborne and PVA based adhesive for leather is used for:
-
Bonding leather to foam, fabric, EVA, rubber, and synthetic surfaces
-
Manufacturing shoes, bags, upholstery, belts, wallets, and accessories
-
Providing flexible bonds that resist bending, folding, and stretching
-
Indoor applications requiring low odor and environmental safety
4. Key Performance Requirements
A high-quality waterborne and PVA based adhesive for leather must provide:
-
Strong initial tack
-
High final bond strength
-
Excellent flexibility
-
Transparent drying
-
Good brushability or roll-coating
-
Storage stability
-
Non-flammable, low-VOC formulation
5. Formulation Components
Waterborne and PVA based adhesive for leather is formulated using PVA emulsion as the primary binder, purified water, polyol-based plasticizers, natural or synthetic tackifiers, cellulose or mineral rheology modifiers, wetting agents, anti-foam additives, preservatives, and optional softening esters or light color pigments.
6. Production Summary
Production begins by preparing the water phase and slowly adding PVA emulsion under constant mixing. Plasticizers and tackifiers are blended to enhance flexibility and tack. Rheology modifiers are added to adjust viscosity, followed by wetting agents, defoamers, and preservatives. After forming a homogeneous mixture, waterborne and PVA based adhesive for leather is filtered and filled into containers for use in leather industries.
7. Properties
Waterborne and PVA based adhesive for leather offers:
-
Flexible, clean-drying adhesive film
-
Strong bonding on natural and synthetic leather
-
High bending and folding resistance
-
Low odor and excellent workability
-
Water-based, non-flammable composition
8. Safety Considerations
-
Maintain containers sealed to prevent contamination
-
Use suitable preservatives to avoid microbial growth
-
Store within recommended temperatures
-
Provide normal ventilation during application
Summary
Waterborne and PVA based adhesive for leather is an environmentally friendly, flexible, and high-performance bonding solution widely used in leather manufacturing and repair. Its simple formulation—PVA emulsion, plasticizers, tackifiers, rheology modifiers, and stabilizing additives—creates a durable adhesive ideal for soft and flexible leather applications.
