Sol-gel coating Classification and characteristics of waterborne coatings - sol /gel coatings Sol-Gel coatings is a new type of coating that has received special attention in recent years. The progress of inorganic nanopowders has promoted the development of sol-gel coatings.The main component of the sol-gel coating is an organic resin and a silane compound, and the silane is hydrolyzed to form a ...
Classification and characteristics of waterborne coatings - waterborne light curing coatings Waterborne light curing coating is a kind of coating classified by curing method. It is a very important kind of coating.In any polymer molecule, a structure in which a reactive group capable of being decomposed by a photoinitiator or a structure capable of being excited by a high-energy radiation to produ...
The basic principles of the following waterborne wood paint formulation design The amount of the emulsion or the aqueous dispersion is as much as possible because the material of the emulsion is mainly composed of a polymer material which is a backbone for ensuring the final film properties; The additive are as few as possible, and they can be used without being used. These additive will be presen...
Water - based coating formulation design system Waterborne coatings, including waterborne wood lacquers, are water-based dispersions and diluents. Unlike conventional solvent-based coatings, the formulation system is a more complex system.When formulating, not only the type of polymer, the properties of the emulsion and the dispersion are concerned. It is also necessary to rationally select variou...
In the formulation of waterborne wood lacquer topcoats, the binder is a key component in forming the film and determining the properties of the film. The binder, ie the polymer emulsion, dispersion or hybrid, accounts for more than 80%, preferably more than 90%.Since the solid content of the emulsion, especially the aqueous dispersion is relatively low (the aqueous dispersion is generally 30% to 3...
Formulation design system for waterborne coatings - film forming AIDS The polymer constituting the emulsion or dispersion generally has a glass transition temperature higher than room temperature. In order for the emulsion particles to be well fused into a uniform paint film, it is necessary to reduce the minimum film formation temperature (MFFT) of the crystallization aid.Film form...

The film-forming aids for waterborne wood coatings are generally alcohol ether type solvents. The most commonly used filming aids such as diethanol ethers, propylene glycol ethers and N-methylpyrrolidone have high and low boiling points.Water-based wood coatings in the summer construction, the water volatilization is faster, that is, the surface is relatively fast, some of the moisture may be encl...
Defoamer is one of the most difficult additives in waterborne wood coatings to control the balance between defoaming and leveling.The paint liquid will generate bubbles during the application due to agitation .If the bubbles present in the paint are not removed in time, the film will dry and form an unacceptable flaw.The paint also produces air bubbles during production, pumping and filling. Defoa...
Character Mineral oil Primer Matte Strong defoaming ability higher price Different product performance differences Large adjustment space Improper selection can cause film defects Influence gloss, flow equality Non-silicone non-oil Various types of coatings, especially in high gloss finishes There are many defoamers on the market, and the choices are very cautious and can be noted in several ways:...
Formulation design system for water based coatings - wetting leveling agent The wetting leveling agent can effectively reduce the surface tension of the system and significantly improve the construction effect of the waterborne wood lacquer.After the addition of the wetting leveling agent, the wetting property and permeability of the paint increase, the leveling property of the paint liquid is imp...
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 lig...
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 matti...
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 environme...
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 p...
