Silyl terminated polymers (MS Polymers) are produced in different forms. The most important family is silyl-terminated polyethers. Such MS Polymer grades containing a polyether backbone and methoxysilyl chain ends are used as the base resin for producing quality sealants and adhesives. Advantages of MS Polymers are excellent adhesion on various substrates, low temperature elasticity (Tg = - 60 °C), good weatherability and good workability. The rise in popularity of MS Polymer products is due to their versatility and well-balanced properties. The functionalized polyether backbone with methoxysilane terminal groups provides excellent performances and makes MS Polymer-based products unique and beneficial. Sealants based on MS Polymer are suitable for a wide range of applications in many different fields: construction industry, marine, general industry sectors, transportation. MS Polymer can be blended with epoxy resins to formulate high strength products. The heterogenic matrix/domain structure consists of the epoxy domains functioning as hard segments in the elastic MS Polymer matrix. This structure is useful to make sealants, adhesives, coatings which are high strength but still elastic. It is expected that the newly developed two component systems, in comparison to the existing ones, will possess considerable improvements in stress-strain characteristics at desirable workability. For the investigation two component systems were made where Component A was MS Polymer with epoxy curing agent and fillers, Component B was epoxy resin with MS catalyst and fillers. For both components viscosity at different shear rates was measured and thixotropic behavior was determined. Curing characteristics, workability and mechanical properties of the obtained epoxy and MS Polymer compositions were evaluated. Mechanical properties were measured at the determined storage times. Workability was characterized by observing pot life, skin formation, thixotropic behavior and stringing characteristics. Adhesion was determined against widely used surfaces in construction like wood, concrete, stainless steel, aluminum, PVC and other substrates.
