Paint grade talcum powder

(45um)% ≥ 98 by the rate of talcum powder in the paper industry, there are three main purposes, namely as a filler, paint and pulp resin control agents. Talc sturdy white paper can increase the opacity and brightness, enhanced ink absorption capacity. Talc pigment has a strong focus on solid, make color prints to get a good color effect. Talc concave abrasion value is very low, thus making equipment and printing equipment wear is very small. Paint grade talcum powder technical indicators Principal grade First grade Qualified Whiteness≥ 95 90 88 Whiteness Passing (45um) ≥ 99.9% 99.5% 99.0% pass rate Particle (20um) 90% 80% 70% Accumulated (10um) 60% 45 % 40% Percentage (5um) 30% 25% 20% a particle size distribution of moisture Moisture 0.5-1.0% Oil Absorption Oil absorption 20-50% LOI ≤ 7% 9% 28% Loss on Ignition PH value of 8-10% of paint grade talc Mainly used for: latex paint, polyester paint, varnish, car putty, road marking paint, marine paint and other products, as the main filler, senior flaky talc used as a filler and color pigments, fibrous talc used suspending agents. Due to strong adsorption of talc, highly dispersed easily in oil, and therefore can prevent paint precipitation, but also as a suspending agent. Talc also regulate luster. Also, because the talc stable chemical properties, hiding power, and prevents the paint layer aging, cracking and improve weathering capabilities.
