Product information and downloads

Whether wood, metal or plastic, this silicone seals window panes in any frame

On account of its perfectly calibrated formulation, the 120 Neutral silicone sealant is particularly suitable for sealing single-pane glass, laminated safety glass and insulating glass in window frames. Its neutral-cure properties ensure ideal adhesion, even on sensitive surfaces such as wooden frames with water-dilutable paint coatings or metal – and all without any priming. Mould stands no chance thanks to its fungicidal ingredients. The sealant’s extra-strong UV and weather resistance and its high level of elasticity also allow it to be used in different construction joints both indoors and outdoors. 120 Neutral meets the most pertinent DIN and EU standards for use in the construction of glass facades and buildings. And as another guarantor of quality, the product is certified and externally monitored by the IFT Rosenheim research institute.
