Committed to Delivering World-Class Adhesive Solutions to the Global Market.

PUR Hot Melt Adhesive

This single-component, 100% solid reactive hot-melt polyurethane (HMPUR) cures with ambient moisture or substrate reactive groups to form a durable three-dimensional network, making it the ideal adhesive for high-speed profile wrapping, edge banding, and laminating of plastic steel PVC, wood-PVC, and aluminum-veneer. Specifically engineered for fast-paced production lines, this eco-friendly formula featuring 0.00% volatility boasts exceptional green strength for an instant, reliable hold and superior thermal stability at 120-140°C with excellent flowability, even at high viscosities. With an adjustable open time of 40-75 seconds depending on production conditions, it delivers outstanding indoor and outdoor adhesion to diverse surface films and veneers, ensuring ultimate weathering resistance against high heat and humidity without delamination.

● High-performance bonding strength for advanced applications
● Excellent resistance to water, heat, and aging
● Flexible adhesive layer adapting to material expansion and contraction
● Adjustable open time to meet different processing requirements
● Ideal for automated and high-efficiency production environments

Product Overview

This single-component, 100% solid reactive hot-melt polyurethane (HMPUR) cures via ambient moisture to form a durable three-dimensional network. Specifically engineered for high-speed production lines, it is the ideal adhesive for profile wrapping, edge banding, and laminating of plastic steel PVC, wood-PVC, and aluminum-veneer.

The formula delivers exceptional initial green strength to instantly secure surface films, combined with an adjustable open time of 40–75 seconds to optimize workflow efficiency. Operating smoothly at 120–140°C with 0.00% volatility, it maintains excellent flow properties despite its high viscosity, ensuring clean and stable application.

Once fully cured, it provides superior indoor and outdoor adhesion with unmatched weathering resistance, enduring extreme heat and high humidity without delamination. For peak performance, the material must be kept sealed against moisture and applied to clean substrates with routine equipment maintenance.

 

Features and Benefits

High Green Strength
Delivers exceptional initial bonding power to instantly hold surface films tightly against the base substrates during high-speed production.

Excellent Weathering Resistance
Once fully cured, it withstands extreme heat, high humidity, and long-term environmental exposure without delamination.

Superior Thermal Stability
Maintains excellent flowing properties and remains highly stable at 120–140°C, even with its relatively high viscosity.

Versatile Adhesion & 0% Volatility
Provides strong adhesion to both indoor and outdoor PVC, veneers, and other surface materials while being eco-friendly with 0.00% volatile organic compounds.
