BRB Silanil 258 is the first widely used coupling agent and has been used for 40 years. One end of its structure with reactive groups such as amino and vinyl, can react with epoxy, phenolic, polyester and other synthetic resin molecules. The other end is alkoxy (such as methoxy, ethoxy etc.) or chlorine atoms which is connected with silicon. These groups can be transformed into silanol in the hydrolysis in water solution or damp air.
BRB Silanil 258s general formula is Y (CH2) nSiX3. Wherein n is an integer of 0 to 3; X is a hydrolyzable group such as chlorine, methoxy, ethoxy and acetoxy; Y is an organic functional group such as a vinyl, an amino, an epoxy group, a methacryloyloxy group and sulfydryl.
Uses
BRB Silanil 258 is an epoxy-functional silane, it is a clear, light straw liquid.
BRB Silanil 258 may be used as a coupling agent in polysulfide and polyurethane caulks and sealants, in mineral-filled or glass-reinforced thermosets and thermoplastics, and in glass roving size-binders.
BRB Silanil 258 is particularly employed as an adhesion-promoting additive in waterborne systems, e.g. improving the adhesion of acrylic latex sealants.
Applications:

Uses
BRB Silanil 258 is used in the production of carbon steel and its pre treatment favors the dry and wet adhesion of epoxy coating.
BRB Silanil 258 is also used to prepare epoxy-functionalized silica nanoparticles, which gives a reactive surface for one-step and high-density protein immobilization.
BRB Silanil 258 serves as a coupling agent and adhesion promoter.
General Description
BRB Silanil 258 is a bifunctional organosilane with three methoxy groups on one side and an epoxy ring on the other. The methoxy groups bind well with glass substrates creating a 3D matrix. The epoxy group is reactive with amides, alcohols, thiols and acids. GPTMS is highly reactive in water and can be used as a linking agent between the surface of the silica and the polymeric matrix.
Pre-treatment of carbon steel with BRB Silanil 258 enhances the dry and wet adhesion while reducing the cathotic disbondment rate of an epoxy coating.
