Surface preparation is key for successful sealing and/or bonding.The use of Sika 209N Primer is critical for successful results in bonding plastic windows to GRP surfaces. The use of Sikaflex – 295UV and Sika Primer 209N is recommended for use in solving leaking windows on C&C Yacht models with plastic windows bonded to the side of the coachroof and prone to this problem.

Sika Primer-209 is a black pigmented liquid of low viscosity which dries by reaction with atmospheric moisture. It is used to prime painted surfaces and plastic substrates prior to bonding with Sikaflex products.

Performance Characteristics:

Sika Primer 209 is particularly effective in promoting adhesion of Sikaflex 265 UV to transparent and translucent plastics and protects the adhesive from UV degradation. Sika Primer-209 is suitable for application to the following substrates:

Paints – Acrylics, Alkyds/melamines, Baked enamels, Powder coatings

Plastics -Acrylic (PMMA), Polycarbonate, Polystyrene, etc.

Because paints and plastics vary so much in their chemical composition, preliminary trials are necessary. Always seek the manufacturer’s advice before using the primer on plastics that are prone to stress cracking, such as acrylics or polycarbonates.
