Core Features

Long-term Sealing & Protection

Fill various gaps, block the intrusion of moisture, dust and corrosive media to achieve long-lasting sealing.

Long-term Sealing & Protection
Elastic Bonding & Fixation

The flexible elastomer firmly bonds metals, ceramics, glass and other materials, and cushions vibration as well as thermal expansion stress.

Elastic Bonding & Fixation
Electrical Insulation Protection

Forms a high-insulation protective layer to prevent short circuits and improve the safety and reliability of electrical equipment.

Electrical Insulation Protection

Features

Flexible curing & easy operation

Simple 1:1 mixing ratio; cures in 12 hours at room temperature or rapidly in 30 minutes at 80°C, compatible with various production cycles
Stable elasticity under wide temperature range

Maintains elasticity under extreme temperatures ranging from -60℃ to 200℃, free of cracking and embrittlement, and resistant to vibration and impact.
Strong Adhesion, Insulation & Weather Resistance

It delivers outstanding adhesion to aluminum alloy and other substrates, with dielectric strength ≥20kV/mm. Featuring excellent aging resistance and medium resistance, its red elastomer enables easy quality inspection identification.
