Product information "Sika® Primer-157"

Sika® Primer-157 – Two-component primer for asphalt & mastic asphalt

Sika® Primer-157 (formerly MSeal P 157) is a high-quality, two-component primer on a polysulphide-epoxy resin basis. It was developed specifically for adhesion promotion for the polysulphide sealants Sikaflex® CR 170 and CR 171 on asphalt and mastic asphalt. Thanks to its film-forming properties, it also offers a sealing protective film.

Product advantages:

  • Film-forming and sealing – for reliable protection of the joint flanks
  • Very good adhesion to asphalt and mastic asphalt
  • Optimal penetration behaviour for permanently resilient bonds
  • Compatible with Sikaflex® CR 170 and CR 171

Areas of application:

  • Bonding agent for asphalt surfaces in road and civil engineering
  • Joint pre-treatment on mastic asphalt for bridges, parking decks or industrial areas

Technical properties:

  • Product type: two-component polysulphide-epoxy resin primer
  • Colour: transparent
  • Packaging: 1 litre combination pack
  • Flash-off time: approx. 4 hours at 20 °C (tack-free), overwork after 8 hours at the latest
  • Application temperature: 15–25 °C (component & substrate temperature)

Substrate preparation:

The joint flanks must be load-bearing, clean, dry and free of oils, greases, loose components, paints and separating substances. The surface is wet-cut or ground with diamond tools to achieve a finely grippy texture. Before application, the substrate must be thoroughly cleaned (vacuumed/blown off) and completely dried.

Mixing & application:

  1. Stir component A thoroughly.
  2. Add component B completely and mix homogeneously with a stirrer at approx. 300 rpm for at least 2 minutes.
  3. Apply with a roller or brush to prepared substrates – no puddle formation!
  4. Before jointing, the primer must be cured tack-free.

Cleaning:

  • Cured primer can only be removed mechanically.
  • Clean hands with cleaning wipes or water & industrial hand cleaner – do not use solvents on the skin.

Certifications & approvals:

  • Tested with Sikaflex® CR 170 and CR 171 on mastic asphalt
  • DIBt approvals: Z-74.6-166 (Sikaflex® CR 170) / Z-74.6-168 (Sikaflex® CR 171)
