  • For porous and smooth substrates: Ideal for a variety of surfaces.
  • Can be used on matt-damp, absorbent substrates: Perfect for demanding conditions.
  • Transparent: Unobtrusive application on various materials.
  • Short flash-off time: Efficient working thanks to fast drying.
  • Easy application: Convenient to handle.

Areas of application:

The reactive primer is specially developed for use with SikaBond®, Sikaflex®, SikaHyflex® and Sikasil® products. It is excellent for use on:

  • Metals

Technical application information:

  • Air temperature: Min. +5 °C, max. +40 °C
  • Substrate temperature: +5 °C to +40 °C, at least 3 °C above the dew point. There must be no condensation on the surface.
  • Flash-off time: At least 30 minutes, at most 8 hours. The minimum flash-off time applies to temperatures above 15 °C; lower temperatures extend the flash-off time.

Material consumption:

  • Absorbent substrates: ~250 linear metres of joint* per litre
  • Metals: ~400 linear metres of joint* per litre

*Joint approx. 20 x 15 mm
