BBT Fire Retardant spray is developed by the BBT-Group in Switzerland. Bio Brandskydd Teknologi is the official distributor for BBT Anti Flame products in Scandinavia and the BeNeLux and is part of Beavers Woodland AB. BBT Anti-Flame is a non-toxic but nevertheless highly effective fire retardant spray on the European market, which allows the conversion of normally flammable materials into non-combustible materials. Properties of the materials, such as the structure of wooden surfaces, colors of textiles or the properties of paper, are not or only minimally affected. The product is colorless and can be reworked with most varnish systems. BT – Antiflame is certified in Switzerland for the use on wood by VKF (Association of Cantonal Fire Safety). At a federal material testing institute in Fichtenholz after treatment with BBT antiflame an improvement of the fire identification number was established and went from 4.3 to 5.3 (200 ° C). This corresponds to the conversion of a medium-combustible building material, which is normally ignitable and continues to burn itself for a long time, into a material which is difficult to ignite and which is difficult to ignite even at an ambient temperature of 200 ° C. BBT – Antiflame was issued with a test certificate for the detection of fire behavior according to DIN 4102 part 1, for absorbent papers and textiles by a German recognized material testing laboratory.
