One-component High Elongation MS Sealant Hybrid Sealant

HM-SEP1923 High Performance Sealant

SEP-1923 is a one component silane end-capped polyether sealant, containing no solvent, no isocyanate, no small organic silicon molecule nor polymer.

It's environmental friendly, low VOC, and it would not contaminate substrate. It is cured by absorbing the moisture in the air at room temperature.

It performs excellent adhesive to variety of construction materials such as concrete, cement, stone, glass, aluminum alloy, PC, PBT, etc., therefore it could be widely used in construction and infrastructure areas.

Typical Application

Construction gap filing & sealing

Adhesive & gap filing of ship building, automotive industry

Characteristics

Good operability: one component, easy to apply.

Environmental friendly: containing no solvent, low VOC, without contaminating substrate.

Good tenacity: 800% super-high breaking elongation, which can maintain good bonding and sealing performance in the case of the building joint displacement.

Excellent adhesive：to most construction materials, such as concrete, cement, stone, glass, aluminum alloy, PBT, PC, etc.

Excellent weather resistance

Paintable
