Features and Benefits
slide 1 of 2
A 1-part, 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 exhibits 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 heat resistance – up to 150°C (302°F) – and cold flexibility. It’s also resistant to water and most solvents.
- Solvent-free
- Resistant to high temperatures up to 150°C (302°F) and high cold flexibility
