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...
The types and functions of surface control agents include: 1.Improve flow and leveling 2.Reduce friction coefficient and increase slip 3.Enhanced scratch resistance 4.Anti-blocking 5.Enhance the arrangement of matte powder, etc. 6.Special feel, such as softness, etc. 7.Others such as improving the water resistance and stain resistance of the coating film On the one hand, they balance the surface t...
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...
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...
Wood coating process 1.There are many large holes in the hard wood, putty or hole adding agent to flatten; 2.Apply closing primer after hole filling； 3.If you need to deepen the surface texture of the wood and highlight the wood grain, you can apply the closed primer and apply the water color； 4.After conditioning the wood grain, apply two closed primer； 5.Finish with top coat.

Water - based acrylic emulsion formulation needs to be considered: water - based acrylic resin composition The choice of emulsion raw materials is the most important decision for engineers when formulating aqueous paint formulations.The main properties of the coating are determined by the resin.A wide variety of water-based acrylate emulsions, including polystyrene-acrylate emulsions, are on the m...
The internal structure of waterborne acrylic emulsion particles will affect several aspects of waterborne paint formulations.According to the order in which the effects are affected, the phase structure will first affect the selection and addition of the filming aid.Different phases have different hydrophilic/lipophilic characteristics, and the oleophilic properties of various coalescents are diff...
What parameters of resin determine coating gloss? Question: What parameters of the resin determine the gloss of the film? Some people say that it is solid content, some people say it is OH value. So, what is the most important determinant of gloss? Answer: There are many parameters that determine the gloss of the paint film. The saturation of the resin: that is, its monomer structure, this index d...
1.The tool Before using the soft brush, thoroughly soak it in clean water, remove excess water, and do not drip. The enamel paint should only reach half the length of the bristles.Brush as fast as possible, gently and smoothly brush the wood grain, do not apply it back and forth repeatedly, because the water-based paint is fast drying and the opening time is short, so it should be completed as soo...
3.Process variations of different paint types-Waterborne wood paint application process 2 Applying a matt lacquer to the varnish can change the coating to a matte finish, while applying a varnish to a matt lacquer reduces the brightness of the film and does not achieve maximum brightness and transparency. The color paint of waterborne wood lacquer can be divided into two types: coloured coating an...
Material property (pu for short) is divided into: Pouring polyurethane elastomer (CPU for short) is one of the most widely used polyurethane elastomers with the largest yield. Thermoplastic polyurethane elastomer (TPU) -- thermoplastic polyurethane elastomer accounts for about 25% of the total amount of polyurethane.Mixed polyurethane elastomer (MPU) - accounts for about 10% of the total amount of...
Glass fiber is an important reinforcing material for the manufacture of fiber reinforced plastics (FRP), and is also used for weaving high temperature resistant fiber cloth.But the glass fiber that has not been treated is brittle, easy to take static electricity after friction, and the surface is smooth, when making the reinforcing material of the resin is not easy to stick with the resin.In the m...
1.The cause of a back adhesion： (1)the paste itself anti-viscosity, especially in the wet weather easy to stick back; (2)After the printing is completed, it is packaged without perfect heat treatment; (3)adjust the slurry formula is not appropriate, adding too much transparent slurry easy to cause back adhesion; (4)transport or storage conditions are not good, in high temperature, high humidity co...
One, extinction principle General can be divided into physical extinction and chemical extinction.Physical matting, is the addition of matting agent, so that the coating in the film when the uneven surface, reduce reflection and achieve low gloss. Two, the kind of matting agent Coating common matting agent can be divided into organic matting agent and inorganic matting agent two categories. 1.Orga...
1.Introduction to silicone acrylic emulsion Silicon-acrylic emulsion is a kind of composite emulsion. It is a copolymer emulsion of organosilicone and acrylate.Acrylic resin has many excellent characteristics, such as weather resistance and light resistance, long time under ultraviolet irradiation is not easy to yellow。In addition, it also has flexibility, so it is often used as a leather finishin...
