Application
3-Glycidoxypropylmethyldimethoxysilane (CAS No. 65799-47-5), silane coupling agent SCA-E87T, is an excellent candidate fformulations employing carboxylated latexes (acrylic, SBR polyurethane, etc. ) exhibiting a pH between 6 8.5.
SCA-E87T silane can be employed as an adhesion promoter crosslinker. It may be suitable fuse as a water stable single component crosslinker in applications such as:
Automotive laminate adhesives
Furniture laminate adhesives
Flocking adhesives
In such applications, SCA-E87T silane should provide a means of replacing a 2 part waterborne adhesive with a single component system. The benefits of a silane crosslinked water stable single component system include reduced scrap, improved process efficiency reduced crosslinker toxicity.
As an adhesion promoter fwaterborne systems such as the acrylic sealant, SCA-E87T silane offers consistent dramatic improvements in water stable adhesion performance.
