SI 7002 Neutral Clear/Black Silicone adhesive sealant
SI 7002 is a neutral adhesive sealant with outstanding mechanical properties, no corrosion to bonding materials, and has good bonding and sealing performance for most materials, low odor and low white fog, high temperature resistance, oil resistance to oil transformer, excellent acid and alkali resistance.
SI 7002 has the following characteristics:
- Low viscosity and good flow type
- High physical and mechanical properties
- It has excellent insulation properties
- It has the function of moisture-proof, dust-proof, anti-corona and anti-seismic buffering
- Good high and low temperature resistance, temperature range of -60 ~ 220℃
- Excellent aging resistance, service life of up to 20 ~ 30 years
- After curing, the colloid does not yellow, does not permeate oil, and has excellent comprehensive performance
