SCA-E87F 3-Glycidoxypropyl-Methyldiethoxysilane (CAS No. 2897-60-1) CAS NO.2897-60-1

3-Glycidoxypropylmethyldiethoxysilane (CAS No. 2897-60-1), silane coupling agent SCA-E87F, is a versatile epoxy organo-reactive silane with two hydrolyzable ethoxy groups. It provides shelf stable non-yellowing adhesion promoter performance while enhancing physical properties in latexes and waterborne adhesive and sealant systems. When SCA-E87F silane is incorporated as a crosslinker or adhesion promoter, it provides improved water resistance and wet adhesion, with good shelf stability.

1. Can be used in place of 3-Glycidoxypropyltrimethoxysilane (SCA-E87M) in many applications, It will generates ethanol upon hydrolysis [which is a volatile organic compound (VOC) but is not a hazardous air pollutant (HAP)] while SCA-E87M generates methanol upon hydrolysis which is both a VOC and a HAP.

2. SCA-E87F silane can be employed as an adhesion promoter or crosslinker. It may be suitable for use as a water stable single component crosslinker. In such applications, SCA-E87F 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 and reduced crosslinker toxicity.

Abstract

3-Glycidoxypropylmethyldiethoxysilane (CAS No. 2897-60-1), silane coupling agent SCA-E87F, is a versatile epoxygano-reactive silane with two hydrolyzable ethoxy groups.
It provides shelf stable non-yellowing adhesion promoter performance while enhancing physical properties in latexes waterborne adhesive sealant systems. When
SCA-E87F silane is incorporated as a crosslinker adhesion promoter, it provides improved water resistance wet adhesion, with good shelf stability.

Application
3-Glycidoxypropylmethyldiethoxysilane (CAS No. 2897-60-1), silane coupling agent SCA-E87F, is an excellent candidate fformulations employing carboxylated latexes (acrylic, SBR polyurethane, etc. ) exhibiting a pH between 6 8.5.
SCA-E87F 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-E87F 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-E87F silane offers consistent dramatic improvements in water stable adhesion performance.
