Polymer ST 48

Technical DataSheet | Supplied by Evonik

Polymer ST 48 by Evonik is a phthalate-based silane-terminated polymer. Offers a good handling viscosity and is therefore easy to apply manually. Exhibits excellent adhesion to concrete, wood, glass and different metals. It is designed for interior or exterior joints such as expansion or connection joints, interior joints for dry walling, joints at staircases. Formulation surfaces are quickly tack-free after application, which ensures rapid processing and avoids long waiting times. Also, it is possible to produce tin-free formulations. Showing a good stress-strain behavior makes Polymer ST 48 suitable for low modulus formulations according to ISO 11600 F&G 25LM/25HM. It has a shelf life of 9 months.
