Features and Benefits

Reactive, polyurethane-based hot melt adhesive system designed for lamination and assembly bonding.
When you want a multi-purpose reactive hot melt that works well on textiles and plastics, TECHNOMELT® PUR 4663 is ideal. This hot melt adhesive system is polyurethane-based and primarily used for bonding and lamination of interior parts. It’s especially suitable for assembly bonding of wooden parts. TECHNOMELT PUR 4663 shows high initial strength, long open time, good cold flexibility, and chemical cross-linking within a few days. The bond joint turns into a thermoset with high final bond strength. It has very high hot resistance and cold flexibility. It’s also resistant to water, most solvents, and high temperatures up to 150°C (302°F).
