According to experts, talc powder additives can increase paint adhesion, prevent mold growth, and improve overall coating performance. The slow economic recovery in 2012 led to a slowdown in the overall market demand growth rate. In 2013, the additive market was still affected by the distressed economy. However, foreign paint giants Troy, Dow Chemical, Arkema and other companies are optimistic about the market. Jeffrey Brown, global marketing manager of Dow Chemical Coating Materials, said that the Dow Chemical Company will launch new additive products in 2013. In order to reduce VOC and improve the appearance and coating function of coating products. Ashland Specialty Additives, a business unit of the Ashland Group, has continued to develop and innovate Natrosol hydroxyethyl cellulose products.

At the China International Coatings Show held in Guangzhou from November 28th to 30th, 2012, Ashland launched a new Natrosol Performax hydroxyethyl cellulose with breakthrough coating thickening technology. The new Natrosol Performax product range is a special hydroxyethyl cellulose thickener with a variety of viscosity specifications, enabling paint manufacturers to achieve a new and perfect experience in terms of production flexibility and quality control. This technology allows the hydroxyethyl cellulose particles to disperse quickly and thoroughly even at low shear rates. It is expected that China's additive market will continue to be in trouble in 2013. Although the additive market was difficult in 2013, the coatings giant did not abandon this market and continued product innovation in the additive market. As the product technology becomes more sophisticated, the additive market will not be very embarrassed.

Liaoning talc can be used in a variety of industrial coatings, especially primers. The primer for steel structure can be used in whole or in part with talc, which can improve the precipitation of the coating, the mechanical force of the coating film and the recoatability. Talc is preferred for many products and flash-bake primers and paints for transportation. Flaky magnesium silicate, including talc, is suitable for metal primers because it can improve sanding and water resistance. The water resistance may be derived from the flake particles extending the path of moisture through the coating film. Because talc has excellent physical and chemical properties such as lubricity, anti-adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good hiding power, softness, good gloss, strong adsorption, etc. The application in coatings is mainly as follows: In coatings, talc is used as a filler, which can play a skeleton role, reduce manufacturing costs and increase the hardness of the coating film. Mainly can increase the stability of product shape, increase tensile strength, shear strength, flexural strength, compressive strength, reduce deformation, elongation, thermal expansion coefficient, high whiteness, and strong uniformity of particle size.

As a filler for polyurethane waterproof coatings, talcum powder can not only reduce the volume shrinkage of the coatings during curing, improve the abrasion resistance and adhesion of the coatings, reduce costs, but also make the coatings have good storage stability and heat resistance.
