【 摘 要 】

Polyether silyl-terminated pre-polymer (SIL) and epoxy resin (EP) based two component systems are most perspective alternatives to the dominant polyurethane adhesive and sealant materials. This study focuses on the influence of the amount of epoxide component on the rheological, indentation, tensile and adhesion properties of SIL/EP composites within a whole range of the component weight to weight ratios. Results show that epoxide content and structure both considerably affect all the investigated properties of the material. Depending on its composition, the obtained materials demonstrate tensile strength in the range of 0.22-4.06 MPa, tensile deformation in the range of 25-1527% and Shore A hardness in the range of 4-96.
