KASTAR 730 Acetic Silicone Sealant – Strong, Durable Seal
Acetic Silicone Sealant is a high-performance silicone that is suitable for one-part sealant application that provides excellent adhesion, flexibility, and durability for a given construction project. Thanks to its short setting time and excellent adhesion to the surface in snowy/icy conditions, this sealant is suitable for sealing glass, ceramics, metals, and other nonporous substrates. The content and base being acetic acid make it ideal for ensuring good wetting adhesion and is recommendable for both interior and exterior use, particularly for construction, glazing, and automotive. It creates a flexible and weatherproof seal that can also resist heat changes and still provide long-term service.

Kastar Acetic Silicone Sealant is formulated as a one-part, moisture-curing, acetic silicone sealant suitable for versatile applications. It gives good wetting characteristics as it can firmly adhere to non-porous substrates like glass, metal, ceramics, and most plastics. Perfect for construction, automobile industries, and industries in general, it Is a tough, weatherproof, and elastic material that can resist high temp and unfavorable weather conditions. After it has fully cured, Kastar Acetic Silicone is then flexible, and durable, and does not age, break up under Ultra Violet light, or swell up when exposed to moisture. This sealant as mentioned above comes out to be very strong and elastic and is used in sealing applications of windows, doors, glass, etc.
- Superior Adhesion: It gives very good adhesion to non-adsorptive surfaces such as glass, ceramics, and metal.
- Waterproof: Ultimately creates a good watertight bond that helps in preventing water penetration at the joints and cracks.
- Temperature Resistant: Good thermal stability, it works effectively at a low temperature of – 60°C to a high of + 180°C.
- Flexible: Stays soft after it has cured enabling movement across surfaces without breaking or reducing its sealing ability.
- Durable: To be compatible with UV radiation, weathering as well and other types of aging to guarantee long-life performance.
- Fast Curing: Cures at room temperature and fast incorporating one for quicker project completion.
- Mildew and Mold Resistant: It possesses good resistance to mold development therefore making it suitable in our shower and kitchen area.
1. Reinstating gaps of doors and windows surrounding the entire frame.
2. Provision of adhesion and sealing of joints of building and construction projects.
3. Adhesion to glass, window, door frame, aluminum alloy, plastic, tile ceramic, and many more.
