One-component High Transparency MS Sealant

HM-SEP1900 One-component High Transparency MS Sealant

SEP-1900 is a one component sealant based on silane end-capped polyether, without solvent, free isocyanate, small organic silicon molecule and polymer. It is environmental friendly, low VOC, and would not dirt the substrate, which is curing by absorbing the moisture from air in the room temperature. It performs excellent bonding to variety of construction materials, such as concrete, cement, stone, glass, aluminum, etc., therefore it could be widely used in construction and infrastructure areas.

Typical Application

◆All internal and external sealing and bonding applications.

◆Used in different construction projects that require transparent and elastic bonding.

◆Perfect adhesion to glass and other transparent materials.

Characteristics

High transparency, would not turn yellow.

Good operability: one component, easy to apply.

Environmental friendly: no solvent, low VOC, without dirt the substrate.

Good tenacity: ＞300% which can maintain sealing performance in the case of the building joint displacement.

Excellent adhesive: bond well to variety materials, such as glass, aluminum alloy, etc.

Excellent weather resistance
