Reactive Silane with control ability for polymerisation
06 July 2023

BRB Silanil® 780 is a reactive silane containing vinyl functionality group and triethoxy group (for hydrolysation), which is slower in hydrolyzing rate than methoxy group providing beneficial in term of polymerisation control ability.

BRB Silanil® 780 is commonly used for modification of various types of emulsion polymerization. It can be added to latex as monomer to form vinyl modified latexes and can also be added to various synthetic rubber to form vinyl co-polymers.

When treated on mineral fillers, its primary task is to increase the dispersing ability. BRB Silanil® 780 can also be used for hydrophobic modification purpose which hydrolysable group is able to bond or interact with inorganic surfaces/fillers such as glass, quartz and steel, and leaving hydrophobic vinyl group on top.

BRB Silanil® 780 has the following benefits: -

• Improves water and abrasion resistance when modifying polymer chains
• Good bonding and adhesion on inorganic fillers or substrates
• Enhances mechanical properties of modified polymers
• Improves scratch resistance in carboxylated latexes
