Bitumen BNK 90 30 is one of the most popular brands of petroleum roofing bitumen, which has excellent performance properties.
Petroleum bitumen BNK 901 30 is used in the process of creating a coating layer that provides reliable and durable protection for roofs and roofing coverings, creating an optimal level of thermal, hydro and vapor barrier, as well as protection against mechanical damage and corrosion.
Petroleum bitumen BNK 90 30 is a composition of hot application. It is laid on the work surface after heating up to a temperature of no more than +200 ° C, at +240 °The composition flares up, and at +300 °C ignites. The surface to be treated with bitumen composition is pre-cleaned and dried. After carrying out all preparatory work, the hot bitumen composition is laid on the work site. It is recommended to use a brush or roller to apply the composition.
