With adaptable pressing times and the option for thermo-curing to enhance water resistance, Everbond PVA GP is a reliable choice for Australian trades seeking a general-purpose adhesive.
Key Features of Everbond PVA GP
- Versatile Application: Suitable for a wide range of woodworking tasks, including surface gluing, assembly bonding, and board joint bonding.
- Easy Cleanup: Water-based formulation allows for simple cleanup with water.
- Adaptable Curing: Variable pressing times and thermo-curing option for enhanced water resistance.
- Safe and Non-Toxic: Non-flammable and resistant to mould, bacteria, and fungi.
- Strong Translucent Bond: Dries to a hard, clear film, maintaining the aesthetic of the wood.
Technical Overview
Everbond PVA GP is formulated for optimal performance in general woodworking applications. Its curing process is based on water dissipation and crosslinking, achieving a firm, water-resistant bond. The adhesive interphase reaches moisture equilibrium in approximately seven days, depending on environmental factors. Thermo-curing with a catalyst can accelerate curing and enhance water resistance. The viscosity of 9300-13500 cP ensures consistent application.
Chemical Properties: Synthetic resin (polyvinyl acetate) emulsion. Non-toxic and non-flammable. Resistant to mould, bacteria, and fungi.
Application Temperature Range: Minimum application temperature of 8°C (46.4°F). Ensure ambient and surface temperatures are within the recommended range for optimal bonding. Ideal timber moisture content is 8-12%.
Application Information
- Required Tools: Brushes, rollers, glue baths, clamps, and cleaning cloths.
- Trade-Specific Tips: Ensure surfaces are clean and properly prepared. Follow specific pressing times for different applications. For enhanced water resistance, use thermo-curing with Catalyst Number 1. Clean tools with water before the adhesive dries.
- Common Issues and Solutions: If the bond is weak, ensure proper surface preparation and clamping pressure. For uneven application, use a roller or brush for even coverage.
Storage and Shelf Life
- Storage Requirements: Store indoors under ambient conditions between 10°C and 30°C (50°F and 86°F). Keep containers closed when not in use.
- Shelf Life Information: 6 months in original packaging.
- Temperature Considerations: Avoid extreme temperatures to maintain product integrity.
Frequently Asked Questions About Everbond PVA GP
Q: How long does it take for the adhesive to fully cure?
A: Curing is by water dissipation and crosslinking, typically taking approximately seven days to achieve moisture equilibrium. Cure time depends on substrate, adhesive mass, timber density, moisture content, and ambient conditions.
Q: Can this adhesive be used for outdoor applications?
A: While resistant to normal humidity, Everbond PVA GP is not waterproof and is best suited for interior applications. Thermo-curing with a catalyst can enhance water resistance.
Q: How should I clean up excess adhesive?
A: Use water to clean tools and surfaces before the adhesive dries. Dried adhesive must be removed mechanically.
Q: What is the ideal moisture content for timber when using this adhesive?
A: The ideal timber moisture content is 8-12%.
Q: What safety precautions should I take?
A: Refer to the MSDS before handling the product. While non-toxic, skin irritation may occur in sensitive individuals. Wear appropriate PPE and ensure adequate ventilation.
Q: What is thermo-curing and how is it done?
A: Thermo-curing involves adding Catalyst Number 1 at a rate of 1% w/w and applying heat. A recommended cycle is 30 seconds at 80°C and 30 seconds at 130°C. This enhances water resistance and speeds up curing.
