This comprehensive guide details the standardized testing process for PUR hot melt adhesive in woodworking flat lamination. It provides PUR adhesive manufacturers and woodworking professionals with a step-by-step method to evaluate the performance of PUR hot melt glue. The article outlines the complete procedure, from ensuring the polyurethane reactive hot melt adhesive is properly melted to assessing its flowability and application uniformity. Key steps include using light inspection to check glue distribution, observing filament formation to gauge tack strength, and a critical 24-hour curing period. The final evaluation involves rigorous peel tests and visual inspections for defects like bubbling or lifting. This process is essential for verifying the superior bonding strength and durability of PUR hot melt adhesive for woodworking, ensuring it meets the high standards required for quality laminated products. By following this protocol, users can reliably predict real-world performance, optimize their application parameters, and guarantee the final product's integrity, making it an indispensable resource for quality control and product development.
