Polymer ST Product Line

- Not available in the Americas - Dioctyl tin carboxylate, catalyst without CMR classification for condensation-curing silicones and silane terminated polymers (POLYMER ST)

Polymer ST 61 is a silane-terminated polymer, that is free of plasticizers. Showing both ex-cellent tensile strength and good elongation makes it suitable for demanding wood floor adhesives. With Polymer ST 61 it is possible to formulate either high strength or soft and elastic wood floor adhesives.

Polymer ST 77 is free of phthalates and is highly recommended for demanding applications where a balanced stress-strain behavior is re-quired as in transport and assembly applica-tions. Examples for the use of Polymer ST 77-based formulations are the assembly of superstructural parts, bumpers, etc. Mechanical fastening is often avoided as it could cause damage to the materials used. In addition, it could negatively affect the design.

The specific product design of Polymer ST 80 enables formulators to produce adhesives with high strength combined with an exceptional surface hardness. Therefore, it is possible to address applications that require lower Shore D levels. Today such applications are mostly addressed through 2C-polyurethanes or epoxy putties.

Polymer ST 81 addresses applications where tensile strength of >> 6N/mm² is required. This is especially important in applications that are covered by 1C and 2C-polyurethanes today. Showing an outstanding high tensile strength Polymer ST 81 allows formulators to enter mar-kets such as wood construction, transport and automotive, assembly as well as light-weight construction.
