Description
SUITIT HH-5031 is single-component fluorescent translucent acetic silicone adopting UV + atmospheric moisture dual curing system. It forms highly flexible elastomer with fast surface skinning and deep curing capacity. The soft elastic layer bears load and absorbs shock, delivering reliable adhesion to glass, various plastics and most metals for industrial, auto and electronic sealing jobs.
Features
- Dual curing: UV rapid surface & deep cure + secondary moisture shadow cure
- EU RoHS compliant eco-friendly formulation
- Outstanding resistance to water, oil and diverse chemical reagents
- High toughness against vibration & thermal shock (-40℃ to 200℃)
- Excellent adhesion to glass, metal and multiple plastic substrates
- Premium comprehensive electrical insulating performance
- Fluorescent formula for easy inspection under UV light
