Sika Primer-209 D (formerly 209 N) is a solvent-based black primer that reacts with moisture and forms a thin layer. This layer acts as a bonding link between substrates and adhesives. This Sika primer is specifically formulated for the treatment of bonding surfaces prior to application of Sika’s 1-component polyurethanes (e.g. Sikaflex-295 UV). This low-viscosity primer may provide excellent adhesion without a prior activation step on certain plastic substrates.

Sika Primer-209 D is used to improve adhesion on many plastics and paints such as Epoxy, Plexiglas (PMMA) and Lexan. We recommend to perform preliminary tests on original substrates under production conditions to determine adhesion and compatibility of the adhesive and material.

Benefits of Sika Primer-209 D

  • Improves adhesion to plastic or paint.
  • Easy to apply by brush or roller.
  • Moisture curing and low viscosity.

Directions for use

  • Make sure the surface is clean, dry and free of grease, oil dust and other contaminants before applying Sika Primer-209 D. You can improve the adhesion to substrates by applying and/or combining a pre-treatment process, such as roughening, cleaning and activation.
  • Shake the can very thoroughly until the mixing ball rattles freely.
  • Continue shaking for another minute (ideal processing temperature is between 15°C and 25°C).
  • Apply a thin but covering coat with a brush, felt or foam applicator. Apply once only. Care must be taken to ensure that this single application gives adequately dense coverage.
  • Tightly reseal container immediately after each use.

Consumption and application method depend on the specific characteristics of the substrate and the production process.
