Kastar 738 neutral high-quality silicone sealant is a professional grade, high-performance silicone sealing material, which is developed for bonding and sealing a range of substrates. Due to its weathering, aging, and versatile substrate compatibility, the product excels in construction, construction renovation, and industry sectors. After curing, it forms a highly flexible sealing layer, and it can be used for a long time; it can be used for bonding all types of materials including glass, metal, plastic, concrete, etc.; Kastar 738 has no obnoxious smell, does not attack the substrate, and safe for the environment; It is ideal for sealing in places requiring high bonding strength and appearance quality. It should be stored in cool and dry conditions and the product has a shelf life of 12 months if it is still in its packing.
- Neutral curing: Many uses and are compatible with metals and alkaline material.
- High adhesion: Higher adhesion to various materials like glass, aluminum, concrete, and other materials
- Strong weather resistance: UV stability, heat stability, cold stability, suitable for indoor and outdoor application.
- Environmentally friendly and safe: No obnoxious smell, as in compliance with the Environmental / Conservation needs.
- Excellent elasticity: After the curing process, one obtains a hard elastomer to fit into the expansion and contraction cycle of various materials.
- Easy construction: Separate putty play, easy to operate, short curing period.
- Building sealing: installations and sealing of doors and window frames. The other defect covered included repairing of the wall joints and concrete cracks.
- Home decoration: Sealant works for waterproofing joints in kitchens and bathrooms and many other areas and specializations. Sealing water and moisture-proof function of tiles and glass.
- Industrial applications: Welding and bolting of pressure equipment. Sealing and waterproof treatment of electric apparatus casings.
- Other applications: Jointing of aluminum-plastic panels in curtain walls. Every type of decoration and engineering work requires the highest level of seal.
