Low Modulus Sealant Polymer KERILON® 201S is alkoxy silane terminated polyether polymer. Ecofriendly Construction Sealant based on it is a kind of Construction Sealant Suitable for a wide variety of interior and exterior applications including, subfloor assembly, interior drywall installation, landscaping bricks/blocks, natural stone and mirrors.
The main difference between adhesives and sealants is that sealants typically have lower strength and higher elongation than adhesives do. When sealants are used between substrates having different thermal coefficients of expansion or differing elongation under stress, they need to have adequate flexibility and elongation. Sealants generally contain inert filler material and are usually formulated with an elastomer to give the required flexibility and elongation. They usually have a paste consistency to allow filling of gaps between substrates. Low shrinkage after application is often required. Many adhesive technologies can be formulated into sealants.
