Product Overview
1-COMPONENT ASSEMBLY GLUE (OUTDOOR) TH-V21 (PREMIUM), categorized under 1-COMPONENT PVAc-D3 ASSEMBLY GLUE (EN204/D3) (OUTDOOR ASSEMBLY GLUE), is a high-quality, modified single-component Polyvinyl Acetate (PVAc) adhesive. Specially engineered to strictly meet the international standard EN 204/D3, it possesses exceptional water resistance and superior high-level moisture resistance. Offering the advantage of a single-component system that is extremely easy to use, featuring fast curing speeds, and forming a highly aesthetic transparent glue film, TH-V21 achieves ultra-strong bonding durability. It serves as the perfect structural solution for outdoor wooden products exposed to harsh weather conditions.
Technical Applications
This product is flexibly and widely utilized in bonding and production processes for premium exterior and interior woodwork requiring high resistance to mold and moisture:
- Specially engineered for bonding natural wood, edge-glued panels, and technical joinery that demand high mechanical and physical durability.
- Optimally applied to a wide variety of materials including solid wood, MDF, HDF, and Plywood.
- Directly used in manufacturing outdoor wooden door systems, premium furniture, kitchen cabinets, flooring, and moisture-prone structures.
- Specialized for joint assembly processes, edge banding, surface veneering, and reinforcing 45-degree miter joints with exceptional strength.
Safety & Adhesive System Storage
Safety recommendations for workshop production and adhesive system storage:
- The product is completely **Formaldehyde-free**, ensuring maximum environmental friendliness and safety for carpentry workshop operators.
- Avoid direct contact of the glue with eyes and sensitive skin areas. Wear safety goggles or basic protective gear when operating automatic glue coating machinery.
- Store and maintain the glue containers in a cool, dry place. Absolutely avoid freezing environments that can destroy the adhesive structure.
- Always seal the lids of storage tanks or plastic glue containers tightly immediately after use to prevent air exposure, which causes surface skinning.
