Waterborne paint formulation design system - pH regulator Waterborne wood coatings may also need to adjust the pH when necessary.Most emulsions or aqueous dispersions have been adjusted to a pH of 8 to 9 when they are produced, eliminating the need for pH adjusters when making paint.If the pH value is different, add 0.05% to 0.1% of the pH adjuster during the paint making process, and adjust the pH of the paint to 7-9.Many waterborne wood lacquers can only be stabilized under neutral to slightly alkaline conditions. When the pH is too high or too low, the lacquer may cause flocculation, sedimentation, coarsening, and deterioration of construction performance. The pH requirements of different systems are different. Therefore, the pH of the waterborne wood coating is adjusted according to the system, and the compatibility with the preservative in the formulation should be considered.It should also be noted that the addition must be diluted with water in multiples to avoid causing the system to produce particles.

Water-based coating formulation design system - preservative Water-based wood coatings are water-based systems that are easier to bring into bacteria during production and are more susceptible to microbial degradation during storage. Therefore, the type and amount of preservatives should be properly added during formulation to prevent system and coating corruption.From the perspective of environmental protection, it should use a less toxic preservative, and also pay attention to the compatibility with the system, and must be diluted with water when adding, Otherwise, flocculation and undesirable phenomena will occur with the system. In general, the use of isothiazolinone preservatives in an amount of 0.1% is sufficient to prevent mildew of the paint during storage.After adding 0.1% preservative, sealing storage for two or three years is not a problem.

Water - based coating formulation design system - matting agent Types and characteristics of main extinction agents Types Features Organic matting agent (synthetic wax) It can not only extinction, but also increase the surface smoothness, enhanced hand feeling and anti-settling property of the coating film. However, such matting agents often affect the transparency of the coating film and even affect the interlayer adhesion of the coating film. Inorganic matting agent (gaseous silica) Organic matter surface treatment dispersity, anti - settling and coating handle, etc Sinograce Chemical produces water based additives, such as thickener, crosslinking agent, wetting agent.

Water - based coating formulation design system - matting agent Matting agents are additives used to control the gloss of waterborne wood coatings to meet the broad needs of mainstream matt paints in today's market.The extinction mechanism of the matting agent can be arranged in an orderly manner on the surface of the coating film, so that the surface of the coating film is uneven, causing the light on the surface of the coating film to diffusely reflect, thereby achieving the purpose of extinction. The solid content of the resin used in the waterborne wood coating is relatively low, and the effective component of the waterborne wood coating is not high. In addition, it is a dispersion system, so the matting of the waterborne wood coating is relatively easy, but the matting of different waterborne resin systems is difficult. Generally, the acrylic emulsion is relatively well-extruded than the aqueous polyurethane dispersion, but is better than the aqueous polyurethane dispersion in terms of anti-settling properties.Therefore, the selection of matting powder must be considered in different systems and uses.The matting agent can select the refractive index similar to the refractive index of the water-based resin to reduce the transparency of the coating film, and also consider its matting effect, dispersibility, anti-sinking property and hand feeling in the system.
