Flexible adhesive sealants

Somewhere in the whole catalogue of adhesive families, the product is classified as a sealant and not necessarily as an adhesive . The application itself will tend to define the difference as much as the generic adhesive type. Very often, in order for a sealant 

This graph is not entirely correct as there will always be exceptions to the categories but it does show that there is no distinct definition between an adhesive and a sealant.

With a new generation of flexible adhesives/sealants on an MS polymer base, the firm of Henkel Teroson inHeidelbeig is offering yet more application possibilities. The Terostat MS family of environmentally friendly products stands out above all for its expansion into yet greater toughness. Traction toughness has been increased up to 2.5 Mpa (DIN...

The market is dominated by flexible foam applications (43% in the United States) and rigid and semi-rigid foam (29%). Cast elastomers (4%) and RIM elastomers (3%) have only specialised outlets. The remaining sizeable 21% of the market cover such diverse uses as thermoplastic rubbers, surface coatings, adhesives, sealants and synthetic leathers. 

Like the 1-RTV systems, the two-part room temperature vulcanization systems (2-RTV) cure to produce flexible elastomers that resist humidity and other harsh environments. Interestingly, they display primerless adhesion property to many substrates, and are used in silicone adhesives, sealants, seals, and gaskets, to name a few.

Di- and poly-isocyanates are mainly used in the production of polyurethane rigid or flexible foams (for insulation and in furniture), adhesives, sealants, surface coatings, elastomers and fibres [2007,2072,2165], whilst mono-isocyanates are employed in the synthesis of substituted ureas and carbamates (Section 4.7.3) for medicinal, agricultural and other... 

Polyurethane products and formulated systems are used in rigid foams, flexible foams, adhesives, sealants, coatings and elastomers, as well as in many other applications. Propene glycols are used in a wide variety of end-use and industrial applications, from unsaturated polyester resins, cosmetics and household detergents, to paints and automotive brake fluids. Propene glycol ethers are commonly...
