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... 

An interpenetrating polymer network (IPN) consisting of an epoxy and an elastomer has been developed by Isayama.29 This is a two-component adhesive-sealant where the components are simultaneously polymerized. It consists of the MS polymer, developed in Japan by Kanegafuchi and commonly used in sealant formulations, with the homopolymerization of DGEBA using a phenol catalyst and a small amount of silane as a graft site to connect the MS polymer and epoxy homopolymer networks. 

Edward M. Petrie has been active in the adhesives industry for over 37 years—both in the formulation and the end-use sides of the industry. He has BS (Chemical Engineering) and MS (Polymer Science) degrees from Carnegie Mellon University and an MBA from Duquesne University. 

The excellent adhesion of MS Polymer sealants to conventional construction substrates such as glass, metal, and plastics (e.g., PVC) is derived finm the widely used silane adhesion promoter V-(P-aminoethyl)-3-aminopropyltrimethoxysilane, DYNASYLAN DAMO-T. Another aspect of using a diaminosilane is the intrinsic change of pH that results in fast hydrolysis and condensation reactions of the MS Polymer . To guarantee a certain shelf life, MS Polymer sealants are generally formulated with vinyltrimethoxysilane, DYNASYLAN VTMO as a water scavenger. 

The goal of the research reported here was to determine the effects of non-sensitizing diaminosilane adhesion promoter DYNASYLAN 1146 on the mechanical properties and the adhesion of a standard MS Polymer sealant. DYNASYLAN DAMO-T is used as a reference. 

Summarized below are the effects of two diaminosilane adhesion promoters (DYNASYLAN DAMO-T and DYNASYLAN 1146) on MS Polymer sealant properties based on the above given formulation ...

Most of the pyrolysis FI/FD studies in the literature have been done in the Py-Fl-MS mode. An alternative approach is to place the polymer (from solution) directly on the field emitter, and then heat the wire to induce pyrolysis. Some of the earlier studies from Schulten s laboratop used this method (Py-FD-MS). Polymers examined were polyamides and a polyester. Derrick et al. reported the Py-FD-MS analysis of a poly(olefin sulfone). ...

A technology which is parallel in concept to crosslinkable HDPE is based on an end-group functionalization of polypropylene oxide [24], The result is a liquid polymer which cures in the presence of moisture to form conformable low-cost sealants and caulks (Eq. 6). The technology has been commercialized by Kaneka under the name MS polymer.
