SL-712 Pure Silica Powder Equal To ED5

SKYSIL SL-712 SILICA POWDER FOR INDUSTRIAL COATING SL-712 is a high effieciency silica matting agent that is equal to Grace ED5, no matter is chemical parameters or usage industries. With special wax treatment on surface, it can provide double functions including precise matte effect and long-lasting protection.Extreme operating tolerance: 99.0% silica content (dry basis) combined with ≤7.0% loss on ignition (1000°C) keeps residual impurities below the industry standard of 60%, completely blocking siloxane migration in a 230°C baking environment. The active silanol groups retained on the original, untreated surface (NONE) increase the catalytic cure rate in epoxy coal tar systems by 18%, and pass a 2400-hour neutral salt spray test (ISO 9227) to verify long-term protection. Its weakly acidic nature (pH 6-7, 5% solution) provides a key guarantee for chemical stability, inhibiting yellowing in amine-catalyzed construction machinery primers. The ΔE value of the light gray coating…
