Areas of application
BORNIT® Hot Compound Primer Spray is used for priming substrates, and in that for improving adhesion for various bitumen construction materials as follows:

• Substrate priming for BORNIT® BORNIthene Plus
• Priming for BORNIT® Hot Sealing N1, BORNIT® Hot Sealing TL, BORNIT® Hot Sealing Rail, BORNIT® Hot Sealing PS
• Bonding for BORNIT® Bitumen Joint Sealant 2C
• Improvement of adhesion on asphalt surfaces prior to applying BORNIT®-Crack Tape
• Priming of joint flanks prior to processing any BORNIT® Joint Tapes
• Improvement of adhesion for bitumen profiles and tapes (BORNIT® Triangle Tape, Trapezium Tape, Alu Tape)

Type and properties
BORNIT® Hot Compound Primer Spray is a sprayable, quick-drying, polymer plastic-containing primer. Using the special spraying can with the user-friendly 360° tilting valve, small surfaces can be primed without any problem without having to use further tools. The product penetrates well into the substrate, has a dust-binding effect and dries fast. Tested according to ZTV Fug-StB 15 / TL Fug-StB 15.

  • easiest handling without brush or roller
  • thus, no tool cleaning required
  • immediately ready for use
  • economical consumption
  • universally suitable for small surfaces
  • good adhesion properties and fast drying
  • high penetration capability and wetting of the substrate

The substrate must be clean, dry and grease-free. Remove loose particles prior to application of the primer.

Prior to processing, store the product at room temperature. Shake the can vigorously before use. Uniformly spray onto the substrate from a distance of approx. 25 cm. Only perform subsequent work after complete thorough drying of the primer!
