Bitumen Primer D-41 Exporter and Supplier

Bitumen Primer D-41 is an Asphaltic Primer suitable for uses in roofing, dampproofing and waterproofing. It is manufactured as a surface dressing to masonry or concrete to improve the bond of bituminous materials.

Bitumen Primer D-41 is an excellent quality universal primer, manufactured from a special type of bitumen. It is solvent based and commonly applied onto various substrates (concrete, concrete blocks, bricks, foam concrete, fiber and steel substrates) to improve bonding of bituminous products. Tiger Bitumen Primer D-41 is in accordance with ASTM D-41.

Bitumen Primer Content

To Liquid Cutback Asphalt, containing 30 wt.% of mineral spirits solvent was added 10 wt.% of p-bromobenzotrifluoride to provide a liquid Bitumen Primer D-41 having a VOC concentration of 186 gll and a flash point of 110°F. The resulting Bitumen Primer D-41 composition was rolled at ambient temperature on a plywood roof deck in a 6 mil thick layer. Alternatively, the composition can be sprayed or poured on the deck. The primer layer was then covered with an asphaltic base sheet which was nailed to the deck through the primer under ambient temperature conditions. A granular surfaced bitumen cap sheet was then applied over the secured base sheet by torching.
