Bitumen 85/40
Bitumen 85/40 is mostly used to spray on the concrete and coating.It has a softening point between 80 to 90 and penetration between 35 to 45.
How does Asphlat 85/40 produce?
Asphalt is a type of hydrocarbon and after the destination and removal of hydrogen, more carbon will be removed and become harder. By injecting hot air to the bitumen the oxygen of air will combine with hydrogen of the bitumen and make H2O and vapour and the remain bitumen is more carbon content and is called oxidized bitumen.
Packing and method of peeling
We are able to supply the bitumen 85-40 in 25Kg meltable bags,50Kg meltable bags,25Kg craft bag,50Kg craft bags,25Kg carton boxes. In 20ft container, we can supply 22.8MT bulk or pallet. In case you are looking for drum packing it is possible in 185Kg Net and 220Kg drum.
Usage and application
It is used for isolation and insulation of concrete surface coating, pipe coating, asphalt shingle, bottom sealing of carpet, paint and primer, mastic and membrane roof sheet, laminate and adhesive, roofing and flooring, and enamel.
How to order?
The optimum quotation is required to clear packing, quality, and destination to be able to quote accordingly. We have sales agent in many many countries and if you looking for local purchase we are able to deliver DDP to the project.
Safety of usage and work
When asphalt 85/40 is in room temperature it is 100% safe and just should be in a proper storage warehouse to be away from acid and fire but whenever it is at high temperature need to care about since the temperature is more than 230 centigrade.
