HINCOL CUTBACK MC70
HINCOL CUTBACK MC70

Priming consists of spraying a primer onto the compacted gravel or crushed rock base. This is carried out to prepare the surface for the subsequent seal coat and to assist in waterproofing the pavement.

Hincol Cutback MC70 is a specially formulated cutback bitumen primer designed for efficient spraying and good adhesion to prepared bases and stone.

It is designed for application on highly porous surfaces to improve the integrity of a loosely bonded substrate surface. The increased viscosity resists total penetration into the road and helps bond loose material hence strengthening the surface. Suitable application rates range from 0.7 to 1.2 L/m2.

  • Application Temperature: 35 to 55 degrees C
  • Short Term Maximum Temperature: 60 degrees C
  • Long Term Storage Temperature: Ambient
  • Maximum Safe Temperature: 80 degrees C
