Technical Information 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).

Application Information Surface Preparation Surfaces must be clean, dry and free from grease, oil and dust. Surface treatment depends on the specific nature of the substrates and is crucial for a long lasting bond. Application The optimum temperature for substrate and sealant is between 15 °C and 25 °C. For optimum performance the joint width needs to be designed according to the movement capability of the sealant based on the actual expected movement. The minimum joint depth is 6 mm and a width / depth ratio of minimum 2 : 1 and maximum 4 : 1 must be respected. Joints deeper than 15 mm must be avoided. For backfilling it is recommended to use closed cell, sealant compatible foam backer rods e.g. high resilience polyethylene foam rod. If joints are too shallow for backing material to be employed, we recommend using a polyethylene tape. This acts as a release film (bond breaker), allowing the joint to move and the silicone to stretch freely. Tooling and finishing Tooling and finishing must be carried out within the skin time of the sealant or adhesive. When tooling freshly applied Sikasil WS-605 S, press the adhesive to the joint flanks to get a good wetting of the bonding surface. No tooling agents must be used. Removal Uncured Sikasil WS-605 S can be removed from tools and equipment with Sika Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically. Hands and exposed skin have to be washed immediately using hand wipes such as Sika Cleaner-350H cleaning towels or a suitable industrial hand cleaner and water. Do not use solvents on skin. Overpainting Sikasil WS-605 S cannot be overpainted. Application Limits Most Sikasil WS, SG, IG and WT, silicones manufactured by Sika are compatible with each other.
