Committed to Delivering World-Class Adhesive Solutions to the Global Market.
This moisture-cured, one-component reactive polyurethane liquid PUR adhesive features excellent film flexibility, rapid drying speed, a superior foaming effect, and outstanding water resistance. Highly versatile and engineered for challenging substrates, it is perfectly suited for splicing wood with a high moisture content of 20% to 60%, bonding oily or high-hardness wood species, and joining dissimilar materials such as melamine surfaces to wood, gypsum board, HPL, and metal. With a 100% solid content and a viscosity of 1000–3,000 CPS, it provides a flexible 1-to-10-minute bonding window, foams within 3 to 5 minutes, and requires 4 hours of pressure time; for optimal results, the bonding surfaces must be smooth, clean, and free of dust or oil, while storage and application environments should be kept away from excessive humidity and temperature to prevent premature curing.
● High bonding strength for demanding applications
● Excellent resistance to heat and moisture
● Good compatibility with various substrates
● Flexible adhesive layer for enhanced durability
● Suitable for automated production processes
This one-component, moisture-cured reactive polyurethane adhesive (Liquid PUR) provides an excellent combination of film flexibility, rapid drying, and superior water resistance. Its unique foaming effect allows it to expand slightly to fill gaps, ensuring a flawless, structural-grade bond even in high-moisture or demanding environments.
It features exceptional adaptability for challenging substrates, successfully splicing damp wood with 20% to 60% moisture content and oily, high-hardness timbers. It is also ideal for cross-material bonding, reliably joining melamine surfaces, gypsum board, HPL, and metals for furniture and construction applications.
Designed for efficient workflows, it offers a 1–10 minute bonding window, foams within 3–5 minutes, and requires 4 hours of pressure. For optimal results, substrates must be smooth and clean, while storage and production areas must be kept away from high temperature and humidity to prevent premature curing.
● Moisture-Cured & Fast-Drying
As a one-component reactive polyurethane adhesive, it reacts quickly with ambient moisture to cure rapidly, significantly speeding up production workflows.
● Excellent Flexibility & Water Resistance
The cured glue film maintains superior flexibility to absorb material stress while delivering outstanding water resistance, making it durable in damp environments.
● Gap-Filling Foaming Effect
It features a unique foaming action (expanding within 3–5 minutes) that perfectly fills microscopic gaps and uneven surfaces, ensuring tight, seamless structural bonds.
● Exceptional Substrate Adaptability
It easily bonds challenging materials, including damp wood (20%–60% moisture), oily or high-hardness timbers, and dissimilar substrates like melamine, gypsum board, HPL, and metal.
