Sika Primer 209-D
- Moisture-curing primer
- Easy to process
- Contents: 250 ml
Sika Primer 209-D (formerly 209-N) is a solvent-based black primer, which reacts with moisture and forms a thin layer. This layer acts as a link between substrates and adhesives. This Sika primer is specifically formulated for the treatment of bond faces prior to application of Sika’s 1-component Polyurethanes. (e.g. Sikaflex 295UV). This low viscous primer might provide excellent adhesion without previous 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 on substrates by applying and/or combining a pretreatment process, such as roughening, cleaning and activation.
- Shake the can very thoroughly until 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.
