Applications: Andisil® 158 Silane is a high performing crosslinker for one component moisture cure RTV silicones. Its relatively low MW can reduce the total crosslinker requirement by ~25% as compared to an oxime crosslinker.

As it cures it releases acetone, which is VOC exempt. Due to this, Andisil® 158 Silane contributes no VOCs to the finished RTV allowing for very low VOC RTVs to be formulated

Due to acetone’s neutral character, Andisil® 158 Silane can even be used on corrosion sensitive substrates such as metal and marble

Preferred crosslinker for use in oxime silicone sealants

Very fast curing RTV with excellent adhesion and good shelf stability can be obtained

Andisil® 158 Silane offers superior quality to the production of silicone rubber
