Nempal 111 Weatherproof Silicone Sealant  |  Versatile 100% Neutral Silicone Sealant  |  100%中性耐候硅酮密封胶

A one-part, high-performance, neutral-curing, 100% silicone sealant recommended for weather sealing applications in curtain wall, building facades, door and window systems, roofing systems, and various other architectural or industrial sealing applications where long-term durability is expected.

The excellent adhesion on a wide range of substrates and the tooling characteristics of the sealant make it a superior choice for applicators. It will cure under the action of atmospheric moisture and form an elastomeric silicone sealant rubber that is waterproof. Its long durability meets the service performance requirements of most architectural joints. It has excellent resistance to outdoor weathering, UV radiation, temperature extremes, moisture, vibration, airborne pollutants, etc., thus it will not crack or harden even after a prolonged period.

 

Suitable for a wide range of architectural weatherproof sealing applications on common building materials such as glass, aluminium, galvanized and zinc-coated steel, painted surfaces, uPVC, masonry, concrete, bricks, non-oily wood, most plastics, etc.

Typical sealing applications include:
▪ Façade Cladding – Aluminium Composite Panel, Stone
▪ Curtainwall, Aluminium Canopy, Stickwall, Skylight, Frameless Glass Systems, Glass Balustrade, etc.
