Glass & metal silicone sealant all weather sealant NP neutral silicone
Glass & metal silicone sealant all weather sealant NP neutral silicone is a one part neutral cure construction grade silicone sealant that easily extruded in any weather. It cures at room temperature with moisture in the air to produce a durable, flexible silicone rubber seal.FEATURES
- One part, it can be easily used and extruded with common caulking guns.
- Excellent adhesion to most construction materials without the primmer.
- Outstanding weatherproofing ability, resisting to ultraviolet ray, ozone, snow or temperature extremes.
- Neutral cure, non-acidic, will not corrode metal or other corrosion-sensitive material.
TYPICAL USE
- General glazing and weather sealing in curtain wall and building facades.
- EIFS, the non-structural curtain walls and building construction applications.
- Window e.g.: vinyl windows, doors and perimeter joints.
- Surface like glass, aluminium, ceramics, metals, steel, fiberglass, most plastics, tiles, bricks, marble & granite and so on.
