Sempure 1814

BRB Sempure 1814 is a non-ionic 60% active aqueous emulsion containing a reactive silicone oil. It has been specially designed for the hydrophobic treatment of: glass wool and mineral wool insulating materials such as in the manufacturing process of fibreglass boards and mats; and low-density bulk fireproofing materials such as perlite or vermiculite.  BRB Sempure 1814 brings the following key benefits: it retains hydrophobicity on glass, mineral wool, perlite or vermiculite, even after processing at high temperatures; it is compatible with most phenolic resin binder solutions; it gives superior water repellency as compared to a standard silicone emulsion, even at low addition rates; this is especially efficient where elevated application temperatures occur; performance is achieved without changing the process or the binder treatment.
