BRB Silanil® 164, a reactive alkylalkoxysilane containing a long alkyl chain of -C16H33 (hexdecyl) and trimethoxysilyl inorganic group. The hexadecyl group of BRB Silanil® 164 is a hydrophobic hydrocarbon chain delivering excellent water repellency features, thus it is used to modify the surface of construction materials, e.g. concrete and inorganic masonry substrates, to form a protective surface surrounding inorganic particles. These long alkyl chains also improve the dispersability of fillers in organic paints and polymers when it is used as hydrophobizing agent on fillers which improved the mechanical properties.
BRB Silanil® 164 found specific use in following application:-
Water Repellency Agent for Construction Materials - BRB Silanil® 164 can be used as water repellency agent for bricks, stone, concrete, inorganic masonry substrates, e.g. highway bridge decks, airport runways, etc. which the containing mineral particles are able to react with trimethoxysilyl inorganic group in BRB Silanil® 164.
Mineral Filler Treatment - BRB Silanil® 164 can be used as hydrophobizing agent to treat mineral fillers and pigments. The long alkyl chain of hexadecyl group is able to improve compatibility between mineral fillers and organic polymers in application of coatings, adhesives and plastics providing great dispersion, higher filler loading, better mechanical properties and also water uptake reduction.
Additives for Polyolefin Compounding - BRB Silanil® 164 can improve toughness of composites which contains mineral fillers, e.g. wollastonite and polypropylene. It also increases capability of high filler loading by compatibility performance. Moreover, BRB Silanil® 164 can be used as processing aid additive in moisture crosslinked compounds, e.g. XLPE wire & cable, to reduce premature crosslink which may be called scorch retardant and prolong shelf life of compounds.
BRB Silanil® 164 is soluble in non-polar organic solvents e.g. petroleum ether, toluene, xylene, hexane, etc. but it is not soluble in water.
