PUR5118 Black PUR Adhesive
PUR5118 is a single-component polyurethane reactive hot melt adhesive that cures with moisture. This adhesive boasts strong initial tack, high final curing strength, impressive toughness, and exceptional resistance to drops. As it cures, the product undergoes a permanent chemical reaction with atmospheric moisture, ensuring effective bonding on a range of substrates including TP, ABS, PC, PET, PMMA, PA, glass, stainless steel, aluminum and more. It is frequently employed for bonding TP and middle frames in electronic devices.
Features and benefits
- High initial tack strength, fast curing
- After curing, the colloid is hard but not brittle, and the bonding strength is high
APPLICATION
- TP and middle frame bonding of various consumer electronic devices
- Bonding of metal side frames and plastic parts
- Bonding of other structural parts
