Technical Data Lubsil S108
Product-No.: 9108 | IMDS-N0.: 974606
Technical Datasheet
Sealer for Zinc- and Zinc-alloys
Features and Benefits
After application and drying, Lubsil S108 forms an almost invisible, transparent seal with excellent corrosion protection - particularly suitable for passivated zinc and zinc alloys.
- Transparent coating
- Excellent adhesion to a wide variety of substrates
- No impairment of the material properties
- Economical consumption
Typical Applications
- Developed for coating and sealing zinc and zinc alloy substrates
- Compatible with all common passivations (blue, yellow, black, olive, etc.)
- Particularly efficient with Cr(VI)-free passivations
- Meets and exceeds the corrosion protection requirements of the automotive industry
Application Remarks
- Lubsil S108 is supplied ready for use and can be diluted with demineralized water if necessary (10-100% make up concentration).
- Parts to be coated must be free of grease.
- For optimum film formation, it is recommended to preheat the parts to 30-50 °C.
- Typical application process: Dip-spin process with coating centrifuges, alternatively drum coating or rack application
- After application, drying at 50-180 °C with hot air (e.g. chamber or continuous oven) is required.
- To avoid condensation, the parts should not be packaged until they have cooled down completely.
