What These Specs Mean for Your Board
The 25–75 micron dry film range gives you flexibility: thinner coatings preserve component profile and fit within tight enclosures, while thicker applications push closer to the full dielectric and moisture-barrier performance ceiling. Because cure occurs at room temperature (23 °C), no baking equipment is required — the coating reaches handling strength in 2 hours and full hardness in 24 hours, keeping your production line moving without thermal processing bottlenecks.
The verified dielectric strength of >2000 V/mm and salt-fog endurance of 500+ hours per ASTM B117 make this coating directly relevant for or automotive electronics and other assemblies exposed to humidity, condensation, or intermittent chemical splash. The operating temperature window of −40 °C to +85 °C covers typical under-hood and cabin automotive environments as well as general industrial control boards.
Reworkability
Unlike silicone or epoxy-based coatings that require aggressive chemical strippers, this acrylic formulation is reworkable by mechanical removal. If a component needs replacement or a solder joint requires touch-up after coating, the film can be physically removed without solvents — a practical advantage for repair-heavy production lines and field-serviceable assemblies.
Buyer FAQ
Does this product carry MIL-I-46058D and IPC-CC-830 qualification?
Yes. The product is specified as compliant with both MIL-I-46058D and ANSI/IPC-CC-830. These are the two most commonly referenced conformal coating qualifications in military and commercial electronics procurement. Full compliance documentation and test reports are available upon request with your inquiry.
What application methods are compatible with this coating?
The product is supplied as an off-white liquid that cures to a transparent film. Based on its acrylic chemistry and viscosity profile, it is suitable for brush application, spray (aerosol or automated spray lines), and dip coating. For high-volume automated selective-spray equipment, please confirm viscosity compatibility with your specific dispensing system when inquiring.
What is the minimum order quantity and available packaging?
MOQ and packaging configurations (e.g., 1 L bottles, 5 L pails, 20 L drums, or IBC totes for bulk) are available upon request. SW ADHESIVE supports global export packaging and can align with your volume requirements.
What are the accepted trade terms and payment methods?
The manufacturer accepts FOB, EXW, and CIF Incoterms. Payment can be made by L/C or T/T. Specific lead times depend on order volume and are confirmed during quotation.
Are VOC content, shelf life, and material safety data sheets available?
VOC data, shelf life, and SDS documentation are available upon request. Please specify your destination market regulatory requirements (e.g., REACH, RoHS substance declarations) in your inquiry so we can provide the correct compliance package.
Can this coating be used on flexible PCBs or polyimide substrates?
Substrate compatibility beyond standard FR-4 rigid boards has not been verified in the supplied product data. If your application involves flexible circuits, polyimide, or specialty substrates, please flag this in your inquiry for technical confirmation before ordering.
