Epoxy Functional Silane Oligomer

SiSiB® OP3000 is an epoxy functional silane oligomer that may be considered for use as an adhesion promoter or binder in polysulfide, urethane, epoxy and acrylic caulks, sealants, adhesives and coatings. 


SiSiB® OP3000 epoxy functional silane oligomer is a polyfunctional structure bearing gamma-glycidoxy groups, which is an excellent candidate to consider to reduce emissions of methanol upon hydrolysis of the material as compared with monomeric epoxy silanes. 

It typically aids adhesion promotion and crosslinking of water borne or solvent based coatings as well as dispersion of metallic pigments in water borne systems.

Application


  • The gamma-glycidoxy propyl epoxide ring available in SiSiB® OP3000 can react with many different organic functionalities, while the alkoxy silane groups still available on the oligomeric structure typically bond strongly to inorganic substrates. The hydrolytic stability of SiSiB® OP3000 epoxy silane can help provide better shelf life than normal monomeric silanes, thus providing better durability in solvent borne systems. Specific hydrolysis conditions can be applied to hydrolyze the material so SiSiB® OP3000 may be considered for use in waterborne systems.


  • It can help improve bending resistance of 2K HS epoxy primer. It can minimize impact of accelerating catalyst on bending resistance.


Packing and Storage


  • It is supplied in 25kg plastic drum or 200kg steel drum.


  • It is should be stored in a cool and dry place out of direct sunlight.
