Isocyanurate silane 1,3,5-Tris(trimethoxysilylpropyl) isocyanurate CAS:26115-70-8
Abstract
1,3,5-Tris(trimethoxysilylpropyl) isocyanurate CAS:26115-70-8, Silane coupling agent SCA-Y25Y, is a unique isocyanate functional silane. The isocyanate functionality exhibits the typical reactivity of an alkyl isocyanate and will react with most reactive hydrogen containing compounds. The silane portion of these products can then crosslink with each other or be used to adhere to a variety of substrates.

Applications and Performance
SiLinkTM SCA-Y25Y is unique isocyanate functional silane. The isocyanate functionality exhibits the typical reactivity of an alkyl isocyanate and will react with most reactive hydrogen containing compounds. The silane portion of these products can then crosslink with each other or be used to adhere to a variety of substrates.
SiLinkTM SCA-Y25Y provides slower hydrolysis for applications requiring greater open time or enhanced shelf stability, provides superior wet adhesion to glass, metal and other inorganic substrates, resulting bond offers excellent thermal, chemical and UV stable performance.
SiLinkTM SCA-Y25Y is excellent candidates for its unique functionality for use as:
1. Crosslinking for one-part moisture curable urethane adhesives, sealants and coatings when used to endcap diol of polyol polymers
2. Adhesion promoters for one-part moisture curable and two-part reactive urethane systems.
3. Adhesive promoters for silicon sealants or coating seeking enhanced adhesion to organic substrates on which active hydrogen species are present, such as nylon or other plastics.
