CURE MECHANISM Sikasil® WS-605 S cures by reaction with atmospheric moisture. At low temperatures the water content of the air is generally lower and the curing reaction proceeds some-what slower (see diagram 1). The curing speed of the reaction depends mainly on the relative humidity and temperature. Material temperature above 50 °C could lead to bubble formation and has to be avoided. Diagram 1: Curing speed Sikasil® WS-605 S METHOD OF APPLICATION Surface Preparation Surfaces must be clean, dry and free from grease, oil and dust. Surface treatment depends on the specific nature of the...
