General Portrayal of Oxidized Asphalt 75/35
By blowing air through an asphalt flux, oxidized asphalt 75/35, a Semi Solid grade of pure petroleum bitumen, is created. It melts steadily and has a high melting point, flash point, and softening point. When applied hot and given time to cool, it offers better adhesive and waterproofing capabilities than oxidized bitumen, which is employed in the industrial sector. With multinational assessors verifying the level of both quality and quantity throughout transferring to the container and overseeing the manufacturing process by QC by sample test report earlier than the transportation, Petro Bitumen Company assures the quality of Oxidised Asphalt 75/35 to meet the ASTM calibre.
Uses of Oxidized Asphalt 75/35
In the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement, crack sealing, civil works, roofing, construction, sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating, and impregnating agent, and the production of rubber and plastic products industries, oxidized asphalt 75/35 is used. It is used for paving, encompassing government-owned structures, safeguarding metals from corrosion, electrical laminate adhesives, providing the foundation for synthetic turf, applying a waterproof coating to pipes to prevent corrosion, creating Portland gravel roadways, hydraulic applications, producing paint, caulking, mastics, and the waterproofing.
Applications, Storage and Handling of Oxidized Asphalt 75/35
For flow and viscosity, oxidized asphalt 75/35 must be heated twice as hot as the softening point. Interfaces must be dry, clean, and devoid of scattered fragments, formwork, curing agents, imperfections, slurry, etc. To apply asphalt 75/35. Please refer to the MSDS for the asphalt 75/35’s 10-year shelf life with repeated heating and chilling.
Packing of Oxidized Asphalt 75/35
Oxidized asphalt 75/35 is produced by Bitumen Company in various packaging materials and is branded with two numbers representing the point where it softens and penetration ranges. The hardening point of 75 °C and the general acceptance of 35 desi centimetres reach the ASTM requirement. For the convenience and use of the consumers, selections are offered.
