Product Detail

Key Features & Benefits

Long-Lasting Seal

Molecular-level sealing forms a non-permeable barrier.

Water vapor transmission rate as low as 0 g/m²·24hr.

Non-curing formulation ensures flexibility even after 20 years of UV exposure (~4000 MJ/m²).

Universal Strong Adhesion

Excellent adhesion to various substrates: aluminum 33.9 N/cm, cement mortar 38.6 N/cm, color steel 35.5 N/cm.

No primer needed; bonds directly to metal, glass, plastic, concrete, and more.

Extreme Environmental Resistance

Operating temperature range: -40℃ to 90℃.

No cracking after 72 hours at -40℃; no flow after 2 hours at 90℃.

Resistant to oil, chemicals, and aging; suitable for harsh climates like deserts and coastal areas.

Eco-Friendly & Safe

100% solvent-free with no toxic emissions.

Complies with RoHS and REACH, meeting global environmental standards.

Easy Installation

Self-adhesive with release liner for fast application.

Stretch 15%-20% to activate molecular alignment.

Cross-wrapping over irregular cracks boosts shear resistance by 320%.
