Q10: Is an activator required for CP-34 Coating Organoclay Thickener in high-polarity systems?
A: No activator is required. High-polarity systems cover ethyl acetate, methyl ethyl ketone, PMA, polyurethane paints and automotive refinish paints. CP-34 Organoclay can take effect via high-shear self-activation dispersion without ethanol or methanol activation. It can be used directly after high-speed dispersion, fully retaining the transparency of clear coats without haze risks.
4. Dosage & Activation Specification FAQ
Q11: What is the standard dosage of CP-34 Organo Modified Bentonite? Is heating required for dispersion?
A: The general dosage of CP-34 Organoclay is 0.2%-2.0% of the total system weight. It can be well dispersed at room temperature without heating, with differentiated dosage for different application scenarios.
Q12: What is the recommended dosage of CP-34 Organoclay for different coating scenarios?
A: 1. Basic anti-settling scenarios (clear coats, light-colored topcoats): 0.2%-0.5%; 2. Conventional industrial paint scenarios (primers, anti-rust paints, general industrial paints): 0.5%-1.2%; 3. High-build and high-solid scenarios (high-build zinc-rich paints, heavy-duty anti-corrosion paints, unsaturated polyester putty): 1.2%-2.0%. Optimal rheological performance can be achieved by adjusting the dosage accordingly.
Q13: What activators are commonly used for CP-34 Organoclay activation? What are the mixing ratios?
A: 95% ethanol or 95% methanol is adopted as the standard activator. No heating is needed, and the optimal performance of CP-34 Organoclay can be realized with activator assistance. Ratio specification: For general systems, the activator dosage accounts for 40%-50% of CP-34 powder weight; for xylene systems, the activator dosage accounts for 30%-40% of CP-34 powder weight.
