Oxidized Bitumen 85/40

Oxidized Bitumen 85-40

Oxidized Bitumen is produced by either ongoing or Staggered Blowing Process. Heated Penetration Grade Bitumen under controlled setting is blown with air which controls the Oil Content in the Bitumen while it oxidized. In addition the different grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges. Oxidized Bitumen 85-40 Also is based on petroleum bitumen.

RECOMMEND USES:

IT IS USING AS RAW MATERIAL FOR BITUMEN COAT, ROOFING, INSULATION ALSO ISOLATION BITUMEN MEMBRANE SHEET.

SURFACE PREPARATION:

FURTHERMORE SURFACES MUST BE DRY, CLEAN AND FREE OF LOOSE PARTICLES, FORMWORK, CURING PRODUCTS, IRREGULARITIES, SLURRY, ETC.

APPLICATION of Oxidized Bitumen 85-40 :

Oxidized Bitumen SPECIALLY SHOULD BE HEATED DOUBLE TEMPERATURE AGAINST THE SOFTENING POINT TO BE ABLE TO HAVE FLOW AND VISCOSITY.

STORAGE/HANDLING:

10 YEARS WITH MULTI TIME HEATING AND COLDING, PLEASE REFERE TO MSDS.
