Arcvolt CF 210 Acrylic Conformal Coating
A single-component acrylic conformal coating for printed circuit assemblies where rework and field repair matter more than extreme service temperature. It dries by solvent release, carries a fluorescent trace for coverage inspection under ultraviolet light and can be removed locally with solvent so a component can be replaced and the area recoated.

1. Product description
A single-component acrylic conformal coating for printed circuit assemblies where rework and field repair matter more than extreme service temperature. It dries by solvent release, carries a fluorescent trace for coverage inspection under ultraviolet light, and can be removed locally with solvent so a component can be replaced and the area recoated. It is the usual choice for consumer, lighting and general industrial boards.
2. Features
- Single-component acrylic that dries by solvent release
- Fluorescent trace for coverage inspection under ultraviolet light
- Removable locally with solvent for component replacement and recoating
- Applied at 25 to 50 microns dry by selective spray, dip or brush
3. Recommended uses
Protection of printed circuit assemblies in consumer, lighting and general industrial equipment, where boards may need rework or field repair.
Substrates. Populated FR-4 and metal-core boards, solder mask, cleaned and no-clean flux residues, connector bodies and passive component terminations.
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Solvent-borne single-component acrylic | Formulation |
| Appearance | Film carrying a fluorescent trace, visible under ultraviolet light for coverage inspection | Visual assessment under ultraviolet light |
| Drying mechanism | Physical drying by solvent release | Not applicable |
| Dry film thickness | 25 to 50 microns, measured on a witness coupon coated with the assembly or over flat copper areas | ISO 2808 |
| Dielectric strength | 15 to 45 kV per mm depending on film build, stated at the measured minimum thickness | IEC 60243-1 |
| Surface resistivity | Above 1×10^13 ohms per square | ASTM D257 |
| Volume resistivity | Above 1×10^14 ohm cm | ASTM D257 |
| Thermal cycling | 200 to 1000 cycles between minus 40 and plus 85 degrees C with no cracking, delamination or loss of insulation resistance | IEC 60068-2-14 |
| Damp heat, steady state | 1000 h at 85 degrees C and 85 per cent relative humidity, the lower end of the category window, with insulation resistance pass criteria agreed for the project. Assemblies that sit in condensing humidity are the duty of Arcvolt CF 430. | IEC 60068-2-78 |
| Reworkability | Removable locally with solvent; the area is recoated after component replacement | 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 | Selective spray, dip or manual brush |
| Surface preparation | Assembly clean and dry; boards cleaned, or carrying no-clean flux residues confirmed compatible for the assembly. Mask connectors, test points, earth bosses and heat sink faces. |
| Thinner | Only the thinner specified for the grade on the label |
| Applied film thickness | 25 to 50 microns dry, checked on a witness coupon coated with the assembly |
| Drying schedule | Tack free in 10 to 20 minutes at ambient, handling strength in 30 to 60 minutes; optional force dry 20 to 30 minutes at 60 to 80 degrees C |
| Inspection | Check coverage under ultraviolet light using the fluorescent trace |
| Rework | Remove the film locally with solvent, replace the component and recoat the area |
Process. Selective spray, dip or manual brush at 25 to 50 microns dry. Tack free in 10 to 20 minutes at ambient, handling strength in 30 to 60 minutes, optional force dry 20 to 30 minutes at 60 to 80 degrees C. Connectors, test points, earth bosses and heat sink faces must be masked.
6. Storage and handling
Store in the original tightly 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.
