MEDIUM CURING BITUMEN PRIMER (D41)
General information:
- Priming and Tack Coating – D41 bitumen’s suitable for priming are also used for tack coats, which are applied to an underlying surface to help with the adhesion of subsequent asphalt layer.
- Primer Sealing – Where temperatures are too cool for an effective priming operation, or where traffic is likely to upset a primed surface before the final seal can be sprayed, a primer seal can be used to give adequate protection of the pavement for periods of up to 6 to 12 months. D41 bitumen’s suitable for primer sealing can also be used in the manufacture of pre-mix asphalt, which is used in repairs.
- Sprayed Sealing – D41 bitumen’s are used extensively in sprayed sealing applications, particularly in cooler weather where they provide improved initial stone retention due to their lower viscosity.
- Packing: 220, 230, 240(Liter) new steel drum
