Wood closed primer formula solves the outstanding problem of wood grain Wood bulges and deforms or wood grain protuberant,It is a common problem in wood painting. We discussed the causes and solutions of this problem in this year's topic.In the article on wood grain protrusions - water-based paints, we recommend three technical solutions: 1. Use a saturated coating of 3-4% binder solids....
Factors Affecting Shrinkage of Waterborne Coating Films In practice, the main causes of shrinkage are as follows: 1. The substrate is contaminated by oil or impurities 2. Apply a paint to the old paint or finish without sanding 3. The interval between constructions of the two paints is too long 4. Too much defoamer in the paint The following focuses on two factors: defoamer and impurity contaminat...
Application of water-based paint coating technology The Paint coating With water-based solvent: non-toxic, non-irritating, environmentally friendly, in line with modern people's fashion taste, convenient construction, good flexibility of paint film. Paint dilution and master the viscosity of the construction directly mixed with water. Advantages of water-based paint: One of the most environmentall...
Future development of waterborne paint: In foreign countries, the application of waterborne paint is very wide, especially in the application of home decoration is very mature. In domestic already many enterprises are used at inside ark besmear, cane implement besmear is installed wait With the development of waterborne paint technology, waterborne paint will become a very important paint in furni...
Basic knowledge of water-based paint In order to provide product development support to a wide range of waterborne coating formulation technicians and waterborne coatings sales personnel, we hav collected and summarized a large number of domestic and international market trends and technical points. Visit our waterborne coatings knowledge base and you can see all of our formulation techniques and ...
Classification and characteristics of waterborne coatings - Waterborne acrylic coatings The emulsifier that USES when polymerization can be anionic, also can be nonionic or cationic, corresponding latex and the lacquer that make also can call anionic, nonionic or cationic. Acrylic waterborne wood lacquer is a variety of applications that have been used earlier and are still in large quantities. Si...
Classification and characteristics of waterborne coatings - waterborne polyurethane coatings Polyurethane is a general term for a class of macromolecular compounds having a carbamate structure in a molecular structure, and is usually produced by a polyaddition reaction of a diisocyanate and a polyol. In view of the variety of isocyanates and polyols, the resulting polyurethanes can range from soft...
Classification and characteristics of water-based coatings - water-based alkyd paints The vegetable oil is reacted with an acid anhydride after alcoholysis to form an alkyd resin, and the content of the hydrophilic group can be increased to form a water-soluble or water-dispersible resin.Water-soluble water-based alkyds are quite transparent in appearance but have color,The alkyd emulsion was brow...
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...
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...
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...
