Arcvolt SO 210 Anti-Soiling Front Glass Topcoat
A sub-micron hydrophobic anti-soiling topcoat for photovoltaic module front glass, intended to reduce dust adhesion and cementation in dry and dusty sites and to lengthen the interval between cleaning campaigns. Build is kept well under one micron so that the loss in visible transmission stays inside the limit agreed for the project.

1. Product description
A sub-micron hydrophobic anti-soiling topcoat for photovoltaic module front glass, intended to reduce dust adhesion and cementation in dry and dusty sites and to lengthen the interval between cleaning campaigns. Build is kept well under one micron so that the loss in visible transmission stays inside the limit agreed for the project, and the formulation is made to sit over anti-reflective glass without closing the porous layer. It is applied either in the module line or in the field during a cleaning campaign.
2. Features
- Hydrophobic film, initial water contact angle 95 to 110 degrees
- Sub-micron build of 0.1 to 1 micron dry
- Formulated to sit over anti-reflective glass without closing the porous layer
- Applied in the module line or in the field during a cleaning campaign
3. Recommended uses
Front glass of photovoltaic modules in dry and dusty sites, applied to new modules in the production line or to installed modules during a cleaning campaign.
Substrates. Low-iron solar glass, anti-reflective coated solar glass, polymer front sheets, glass on already-installed modules.
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Sub-micron hydrophobic topcoat for glass | Formulation |
| Appearance | Transparent film; loss in visible transmission within the limit agreed for the project | Customer or supplier protocol |
| Water contact angle | 95 to 110 degrees initial, with the retained value after weathering stated in the project specification | ASTM D7334 |
| Applied build | 0.1 to 1 micron dry, held at the low end of the range on anti-reflective glass; controlled by transmission loss and applied wet volume per square metre, not by a thickness gauge | Customer or supplier protocol |
| Accelerated weathering | 2000 to 4000 h xenon-arc exposure, with retained contact angle and transmission limits agreed for the project | ISO 16474-2 |
| Compatibility with anti-reflective glass | Sits over the anti-reflective layer without closing its pores | Customer or supplier protocol |
| Cure window | Ambient cure in 2 to 4 hours, or force cure 10 to 20 minutes at 80 to 120 degrees C | Customer or supplier protocol |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Flow, fine spray or wipe |
| Surface preparation | Glass cleaned and dried, and free of alkaline cleaner residue |
| Applied build | 0.1 to 1 micron dry, set by applied wet volume per square metre and checked by transmission loss. On anti-reflective coated glass the build is held at the low end of the range and transmission loss is measured on the AR glass being coated. |
| Cure schedule | Ambient cure in 2 to 4 hours, or force cure 10 to 20 minutes at 80 to 120 degrees C in the module line |
| Field application | On installed modules, applied during a cleaning campaign after the glass has been cleaned and dried |
Process. Flow, fine spray or wipe application at 0.1 to 1 micron dry on cleaned and dried glass. Ambient cure in 2 to 4 hours, or force cure 10 to 20 minutes at 80 to 120 degrees C in the module line. The surface must be free of alkaline cleaner residue before application. Build at this scale is controlled by transmission loss and by applied wet volume per square metre, not by a thickness gauge.
6. Storage and handling
Store in the original closed containers in a cool, dry, covered area, away from direct sunlight and sources of heat. Shelf life is stated on the label and Certificate of Analysis. Handle and use the product in line with its Safety Data Sheet.
7. Safety and regulatory information
Read the Safety Data Sheet before use. Safety Data Sheets and regulatory declarations are issued by our technical centre against the product and batch supplied, so they are sent on request rather than published. Request a Safety Data Sheet or declaration.
