Advantages

• Strong bonding performance for porous substrates such as wood and veneer.

• Fast setting and easy application suitable for various production speeds.

• Environmentally friendly, water-based formulation with low VOCs.

• Excellent heat and humidity resistance for stable long-term bonding.

• Cost-effective adhesive option for furniture and wood processing industries.

Classification

PVAc adhesives can be divided into:

• Standard PVAc — for general woodworking and veneer lamination.

• Cross-linked PVAc (PVAc-D3/D4) — improved water and heat resistance for demanding applications.

• Modified PVAc blends — designed for faster curing or specific industrial requirements.

Applications

PVAc adhesives are widely used in:

• Flat Lamination — bonding decorative surfaces to wooden panels.

• Veneer Hot Pressing — ensuring smooth, durable adhesion of veneer sheets.

• Wood Jointing — ideal for finger joints, edge gluing, and frame assembly.

FAQs

Q1: What is the difference between PVAc and PVA glue?

A1: PVAc refers to polyvinyl acetate, the chemical base of many white glues. PVA (polyvinyl alcohol) is a derivative, but in common usage, “PVA glue” often refers to PVAc-based adhesives.

Q2: Is PVAc adhesive waterproof?

A2: Standard PVAc is not fully waterproof, but D3 and D4 grade PVAc adhesives offer higher water and heat resistance suitable for interior and limited exterior applications.

Q3: Can PVAc adhesives be used for high-temperature pressing?

A3: Yes, cross-linked and heat-resistant PVAc formulations are ideal for hot pressing applications like veneer lamination or composite board production.
