Tego Surten W 125 Polyether siloxane copolymer Degussa-Goldschmidt Wetting Agents ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) TEGO® Surten W 125 is a wetting agent based on polyether siloxane copolymer. Applications of pressure sensitive adhesives under high dynamics. TEGO® Surten W 125 should be added to the dispersion as supplied. Pre-dilutions are possible and could be beneficial depending on the facilities. Depending on the application in question the required dosage may vary over a wide range (0.1 - 1.0 %); suitable screening test are therefore recommended (initial dosage 0.3 %). Polyether siloxane copolymer. Used as wetting agent for applications of pressure sensitive adhesives under high dynamics. Use level: 0.1-1.0 %.
