Description
SUITIT HH-5033 is single-component fluorescent pale yellow translucent acetoxy silicone adopting UV + atmospheric moisture dual curing system. It forms highly flexible elastic rubber with rapid surface skinning and deep curing performance. The elastic bond line bears loads and absorbs shocks, delivering strong adhesion to glass, metal, ceramic and various plastics for industrial, automotive and electronic assembly sealing.
Features
- Dual curing mechanism: Fast UV surface & deep cure + secondary moisture shadow curing
- Fully compliant with EU RoHS environmental standards
- Superior resistance to water, oil and various chemical solvents
- High toughness against mechanical vibration & thermal shock (-40℃ to 200℃)
- Outstanding unprimed adhesion to glass, metal, ceramic and most plastics
- Excellent comprehensive electrical insulating performance
- Fluorescent formula enables easy visual inspection under UV light
