WATER SCAVENGERS | MOISTURE SCAVENGER | DRYING AGENT
SiSiB® silanes react rapidly with water; they can be used in the formulation of paints and coatings to capture excess moisture coming from the fillers or the surrounding environment.

Benefit of Water Sacvengers:

  Prevent premature cure during compounding
  Enhance uniform curing
  Improve package stability

SiSiB® PC6110 (Vinyltrimethoxysilane) is the most common moisture scavenger in adhesive and sealant formulations. Due to the electron interactions of the vinyl group, the Si-methoxy groups in this silane hydrolyze substantially faster than in saturated aliphatic alkylalkoxysilanes. Any moisture inherently present in the formulation is removed as the methoxy groups hydrolyze (methanol is split off) and the vinylsilane condenses. Other silanes, such as SiSiB® PC5131 (Methyltrimethoxysilane), are also used as water scavengers. The amount of silane added will depend on the water content of the formulation constituents.
