TECHNOMELT® PUR 4663

Known as PURMELT QR 4663

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).
