Arcvolt AS 430 Conductive and Shielding Coating
A conductive coating supplied in two fills: a carbon-filled version at 1×10^2 to 1×10^4 ohms per square for grounding and charge drainage, and a nickel- or copper-filled version below 1 ohm per square for attenuating radiated fields. Attenuation follows conductivity and continuity, so a grade specified only as conductive will not shield.

1. Product description
A conductive coating supplied in two fills for two different duties. The carbon-filled version sits at roughly 1×10^2 to 1×10^4 ohms per square and is used for grounded enclosure interiors, static-free faces and charge drainage. The metal-filled version, pigmented with nickel or copper, is taken below 1 ohm per square, which is the range where a coated surface begins to attenuate a radiated field; attenuation follows conductivity and continuity, so a grade specified only as conductive will not shield. In both cases contact pads, gasket lands and mating edges have to be coated and kept free of overspray from later layers, and the ground path has to be designed in.
2. Features
- Carbon-filled version at 1×10^2 to 1×10^4 ohms per square for grounding and charge drainage
- Nickel- or copper-filled version below 1 ohm per square for shielding
- Applied in two to three passes at 30 to 60 microns dry
- Ground continuity and shielding assessed on the assembled enclosure
3. Recommended uses
Carbon-filled: grounded enclosure interiors, static-free faces and charge drainage. Metal-filled: shielding of moulded thermoplastic, composite and GRP electronics housings, with the ground path designed in.
Substrates. ABS/PC blends, glass-filled polyamide and PBT, composite and GRP housings, moulded thermoplastic enclosure interiors, primed aluminium.
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Conductive coating, carbon-filled or nickel- or copper-filled | Formulation |
| Surface resistivity, carbon-filled version | 1×10^2 to 1×10^4 ohms per square | Customer or supplier protocol |
| Surface resistivity, metal-filled version | Below 1 ohm per square | Customer or supplier protocol |
| Shielding effectiveness, metal-filled version | 30 to 60 dB over 30 MHz to 1.5 GHz on a flat specimen at a surface resistivity below 1 ohm per square; performance on the assembly is assessed separately | ASTM D4935 |
| Shielding, carbon-filled version | Limited attenuation; specified for grounding, not shielding | Not applicable |
| Dry film thickness | 30 to 60 microns | ISO 2808 |
| Adhesion, cross-cut | Classification 0 to 1 on the specified pre-treatment | ISO 2409 |
| Ground continuity | Measured across the assembled enclosure, not only on a flat panel | Customer or supplier protocol |
| Drying window | Force dry 20 to 30 minutes at 60 to 80 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 | Conventional or HVLP spray in two to three passes |
| Surface preparation | Clean, dry and free of release agent and dust |
| Before use | Stir to a uniform consistency so the filler is evenly dispersed, and keep the material agitated throughout spraying, in an agitated pressure pot where one is used, because the metal and carbon fillers settle |
| Applied film thickness | 30 to 60 microns dry, with edge, rib and corner coverage confirmed visually |
| Drying schedule | Force dry 20 to 30 minutes at 60 to 80 degrees C |
| Contact areas | Coat contact pads, gasket lands and mating edges and keep them free of overspray from later layers; the ground path has to be designed in |
| Verification | Measure ground continuity across the assembled enclosure, and assess shielding on the assembly rather than inferring it from panel resistivity |
Process. Conventional or HVLP spray in two to three passes at 30 to 60 microns dry, with edge, rib and corner coverage confirmed visually. Force dry 20 to 30 minutes at 60 to 80 degrees C. Ground continuity is measured across the assembled enclosure, not only on a flat panel, and shielding performance is assessed on the assembly rather than inferred from panel resistivity.
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.
