BRB Silanil® 780 is a reactive chemical containing vinyl functionality and silane hydrolysable group, triethoxy groups, which is slower hydrolyzing than a methoxy group, providing beneficial in term of polymerization control ability. CAS# is specified as 78-08-0.
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, then leave a hydrophobic vinyl group on top.
BRB Silanil® 780 is widely used to modify polymer structures e.g. vinyl modified latexes and various synthetic rubber to form vinyl copolymers, especially in surface coating resin for both of waterborne and solventborne such as acrylic latex which is commonly added in the polymerization step either in preemulsion tank or monomer mixture tank.
