KASTAR 112 PU Sealant – Professional Quality & Durable
KASTAR 112 Professional PU Sealant is a heavy-duty, all-purpose adhesive perfect for construction and industries. It has better elasticity, hardness, and rainy resistance than other gasket materials. Hence it is more suitable for sealing seams and cracks, or opening in indoor and outdoor environments. It has excellent interfacial bond characteristics to different surfaces including concrete, metal, wood, and glass among others hence offering a lasting sealing solution. It cures very fast and offers very good UVR, moisture, and thermal stability making it ideal for deployment in high-performance areas. The KASTAR 112 Professional PU Sealant gives a bright and smooth feel and protection in all its applications.

Acrylic sealant is a water-based material that comes from acrylic resins, which is used especially to seal the gaps in horizontal movement joints of building structures and other construction works. It sets hard within minutes and provides a flexible, strong, and waterproof barrier. Acrylic sealant is used in construction and home improvement to fill gaps around openings like windows and doors, as well as baseboards and fixtures as well as for filling tiny cracks and holes on walls and ceilings. Able to be painted over once it dries, it comes in an array of colors. Non-skinning, thus, easy to apply as well as easy to clean up, acrylic sealant is cheap and suitable in many sealing applications.
This one-component formulation provides a smooth finish which makes using easy. The device offers the shortest safe time of two hours as a drive-away time if installed on vehicles with airbags. As for properties that remain after curing, it has relatively low hardness and high tensile strength and is also extremely flexible and durable. This sealant offers high-capacity extrusion, does not need coats on the glass surfaces, and does not ooze out, interact with pollutants, or corrode either the base material or the surroundings. No water unfitting, a good adhesive property with very high water resistance, and good aging characteristics make it a very durable sealant.
