Description
SUITIT HH-5091 is a translucent, repairable semi-flow deacidified silicone adhesive. It forms soft, high-toughness elastomer after dual curing by UV light and ambient moisture. Its flexible joint bears load and absorbs impact, with good adhesion to glass, various plastics and most metals, suitable for fast cure potting, coating and sealing work.
Features
- Fast UV surface tack-free and deep curing
- Fully compliant with EU RoHS environmental standards
- Excellent resistance to water, chemicals and oil
- High toughness against mechanical vibration & thermal shock (-40~200℃)
- Ideal for bonding & sealing glass, metal, ceramic and plastic substrates
- Superior electrical insulation performance
- Repairable formula for easy rework after curing
