Low Modulus Silicone Sealant – Durable & Flexible
KASTAR LMS Low Modulus Silicone Sealant is a high-performance, one-component silicone-based sealant meticulously formulated to deliver exceptional flexibility and durability for a wide range of construction and industrial applications. Its advanced low modulus silicone polymer technology ensures superior adhesion to materials such as concrete, masonry, metal, wood, glass, and plastics, providing reliable and long-lasting seals that accommodate significant joint movement without cracking or losing integrity. Resistant to UV rays, extreme temperatures, moisture, and chemical exposure, KASTAR LMS is ideal for both indoor and outdoor use in environments that experience substantial thermal expansion and contraction. With a smooth, non-sagging consistency, this sealant is easy to apply using a caulking gun, ensuring a professional-grade finish that maintains its performance and appearance over time, effectively preventing leaks, drafts, and corrosion in dynamic joint areas.
