Description
SUITIT HH-6703 is medium-viscosity thixotropic polyurethane modified acrylic adhesive. It cures rapidly under UV or visible light to form tough flexible bonding layers with strong load-bearing and vibration-absorbing capacity. Thixotropy prevents sagging, delivers superior adhesion to glass, various plastics and most metals, and complies with EU RoHS standards.
Features
- Thixotropic formula, anti-sagging, supports max 0.5mm gap filling
- EU RoHS compliant eco-friendly composition
- Ultra-fast curing under UV or visible light irradiation
- Excellent resistance to water, oil and diverse chemicals
- High toughness against mechanical vibration & thermal shock cycles
- Premium electrical insulating performance
