Technical Selection Guide (FAQs)
+What is the recommended conductive additive for water-based anti-static coatings?
BC-A01 Conductive Carbon Black for its universal compatibility and low addition rate, or the pre-dispersed BC-W Series engineered for water-based materials.
+How do I formulate a light-colored or white anti-static floor coating?
Use BC-B50 Conductive Mica Powder (White) or BC-M12 for inorganic white flooring. For light gray, the Conductive Titanium Dioxide series (BC-T03, BC-T04, BC-T13) provides conductivity without darkening the matrix.
+What is the difference between raw carbon fiber powder and pre-dispersed pastes?
The BC-F series requires high-shear dispersion equipment. Conductive Pastes are pre-dispersed in a liquid matrix — easier to integrate, saving processing time and mitigating fiber clumping or surface exposure.
+How should conductive material be selected based on dry film thickness?
• Ultra-thin films (0.1 – 0.2 mm): BC-F01 carbon fiber.
• Standard thin films (< 1 mm): Pastes such as BC-J1000 or BC-J11A.
• High-build applications (2 – 5 mm): BC-J20A or BC-F11-6.
+Does the SemiJun series cover full ESD floor certification?
Yes — conductive pigments and pastes, Conductive Copper Foil (BC-Z, BC-Z6) for grounding grids, Anti-Static Wax (BC-M108/109) for long-term protection, and Testing Instruments (ACL 800, PC27-7H) for compliance verification.
