The moisture curable silane terminated polymers (hybrid resins) present an attractive regulatory profile because of their low toxicity, but they also present formulators with remarkable flexibility to fit specific industry adhesive properties. However, there is a continuing need for improving the safety profile of the additives required for performance and stability of their formulations. In particular, it has been challenging to replace the moisture scavenger vinyl trimethoxysilane, which has an essential function for shelf life stability of the moisture cure adhesives.
This presentation will present recent developments on moisture scavengers silane technology and their implications on the design and properties of moisture cure adhesives and sealants.
