Areas of Application
Sika® Primer-209D is suitable for application to the following substrates:
- Plastics Acrylic (PMMA)
Polycarbonate ABS, etc.
- Paints Acrylics
Alkyds/melamins
Because paints and plastics vary so much in their chemical compo-sition, preliminary trials are neces-sary. Always seek the manufactu-rer’s advice before using the primer on plastics that are prone to stress cracking, such as acrylics, polycarbonates or ABS.
Method of Application
Surfaces must be clean, dry and free from all traces of dust and grease. Wipe the bond face with Sika® Cleaner-226 and allow to dry. Shake the can of Sika® Primer- 209 N thoroughly until paint mixing ball rattles freely. Mix for an additional one minute and apply a thin, even, coat with a brush or felt pad.
Do not apply at temperatures below 50°F(10°C) or above 86°F(30°C.) Sika® Primer-209 N should be applied once only. Care must be taken to ensure that this single application gives adequately dense coverage. Re-seal container tightly after use. For transparent substrates such as PMMA and PC, bonding has to be done with Sikaflex® 295. If UV-transmission exceeds 0.5%, an additional external UVprotection is necessary.
