Bio White is a refractory coating: it is hard, strong, totally UV resistant and weatherproof. Bio White is a powder which reacts exothermically to form a hard calcium aluminate hydrate crystalline compound. It is normally used impregnated into biotextile, a non-woven textile carrier and reinforcing medium. Bio White has a matt white appearance similar to marble.
Bio White can withstand temperatures in excess of 1400°C.
It sets hard in about an hour. High ambient temperatures accelerate set, so does enclosing to eliminate evaporative cooling. Thermal insulation also accelerates setting. A large casting will set in a few minutes and get so hot as to generate steam explosions.
Bio White will replicate the exact texture of a mould. A perfectly smooth mould generates a glossy finish.
Mixing: add 35 weight parts water to 100 weight parts Bio white powder and mix by hand. Use small quantities of mix at a time, not more than 2kg. It is very fluid, too fluid for a gel coat. It can be made into a gel coat by adding 0,1% methocel J75MS into the powder before mixing water.
