Sikaflex 209N Window Sealant Primer 250ml

Sika Primer-209 N 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.

Areas of Application

Sika Primer-209 N is suitable for application to the following substrates:
Plastics Acrylic (PMMA), Polycarbonate, ABS, etc.
Paints Acrylics, Alkyds/melamin

Because paints and plastics vary so much in their chemical composition, preliminary trials are necessary. Always seek manu-facturer’s advice before using primer on plastics that are prone to stress cracking, such as acrylics, polycarbonates or ABS.
Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

Method of Application

Surfaces must be clean, dry and free from grease, oil and dust. Wipe the bond face with Sika® Cleaner-205 and allow to flash-off. Shake the can of Sika® Primer-209 N very thoroughly until mixing ball rattles freely and apply a thin but covering coat with a brush or felt pad.

Do not apply at temperatures below 10°C or above 35°C.
Sika Primer-209 N should be applied once only. Care must be taken to ensure that this single application gives adequately dense coverage. Tightly re-seal container immediately after each use.
