Everbond PVA Xlink 3

For woodworking, cabinetry, shopfitting, and joinery applications requiring a water-resistant bond, Everbond PVA Xlink 3 is a single-component, self-crosslinking adhesive that conforms to AS 2754.2 1991 and EN204. It bonds all types of timber without staining, and cures under ambient or hot press conditions without requiring mixing.

How it works

Everbond PVA Xlink 3 is a synthetic resin adhesive that cures through water dissipation and crosslinking. Under ambient conditions, it cures to a firm, highly water-resistant bond. Full cure is optimised when the adhesive interphase reaches moisture equilibrium, which typically takes seven days depending on timber density, substrate and adhesive mass, moisture content, and ambient conditions.

For high-volume production, curing can be accelerated by hot pressing. Water resistance can be further increased by thermocuring after mixing Catalyst Number 1 at a rate of 1% w/w.

Numbers that matter

• 8°C minimum application temperature: The lower thermal limit for the adhesive to form a proper bond during application.
• 48% to 50% solids content: High polymer concentration ensuring high bond strength and controlled shrinkage during water dissipation.
• 9,300 to 13,500 cP viscosity: A stable, medium-viscosity white liquid suitable for dowelling, assembly, and laminating.

Where to use it

This adhesive is suitable for assembly bonding, dowelling, laminating, and board joint or block bonding. Compatible substrates and materials include:

• All timber species and solid timber
• Particle board
• Timber veneer
• High-pressure laminates
• Decorative papers

Press times and thermocuring

Minimum pressing times vary by application method and temperature:

• Surface gluing of decorative papers: From 10 seconds
• High frequency gluing (longitudinal heating): From 20 seconds
• Surface gluing of high-pressure laminates (+70°C short-cycle presses): From 60 seconds
• Assembly bonding: 30 minutes
• Board joint and block bonding: 45 minutes

For veneering 1mm to 2mm timber veneer to solid timber or particle board (with timber moisture at 8% to 12%), the recommended thermocuring cycle is 30 seconds at 80°C followed by 30 seconds at 130°C. This requires an adhesive spread rate of 150 to 200 g/m² and a pressure of 4 to 5 kp/cm².

Application and limits

• Adhesive coverage rates: Apply at 80 to 140 g/m² for surface bonding, and 160 to 180 g/m² for assembly bonding.
• Preparation: Ensure the adhesive is completely homogenous before use.
• Clean-up: Wash out brushes, rollers, and glue baths with water before the adhesive dries.
• Storage limits: Store indoors under ambient conditions between 10°C and 30°C. Keep containers closed when not in use. Shelf life is 6 months in original packaging.
