The product is recommended to be used in water-based thixotropic system whichhigh-viscosity shear-thinning is required, water-based coating, home-care, industry-cleaning, ceramic-glaze, agriculture chemicals, oil-field and gardening.
RDS is excellent thixotropic agent in organic solvent, the solvent content should be controlled and not exceeded the following concentration: Methyl alcohol 50%, Ethyl acohol 30%, Isopropyl alcohol 30%, Ethylene glycol 50%.
RD is need to be mixed with water-based system or water in the condition of high-shearing force. Add the RD into the system before the addition of other ingredients, disperse and grind, then add the other ingredients. The RD can be formulated into pre-gel, then be added into the system.
If use the softened water, the viscosity will gradually increase within 24 hours, while in the hard water, the viscosity increased rapidly, using the warm water is conducive for dispersing.
Compare with the pure aqueous system, the viscosity of water-borne and solvent borne systems is higher. The more of organic solvent the system contains, the lower of transparency and stability the system becomes.
RDS pre-gel is stable in the acid and alkaline situations. It is best effect while the PH is 5.5-13. RDS is not suitable for acid system.
The recommended supplementation ratio(ratio of the gross ingredient) is 0.5-3%, please choose the best supplementation according to the different demands actually.
The product is packed by 25kg/paper bag, please store it in a cool and dry place. The storage period of the product is up to 12 months at least, since the delivery date. After it all, the product should be inspected before usage.
