2018.6.22,customers from Canada have come to visit our company. Foreign trade manager and relevant personnel warmly welcome our customers, and introduced our product which they are interested in detailedly. The peelable coating is designed using water based polyurethane that can be applied to smooth, non-porous surfaces and simply peeled off once dry. All peelable coatings may be applied with wate...
Phenomenon : Part of the water-based paint film from the primer uplift, which contains gas or liquid, showed uneven distribution. Cause 1.When the water-based paint is applied, the dry water-based paint film is exposed to rain. 2.Apply a water-based paint primer to the wet substrate. 3.Water - based paint film is affected by acid - base and heat. Amelioration 1.Considering the gas phase conditions...
Phenomenon: Wood coating water - based varnish after the grain fuzzy, grain color and luster differ, failed to retain the original style of wood. cause 1.Transparent putty transparency is poor or scraping too thick, reduce the clarity of wood grain. 2.Water-based paint storage time is too long, pigment precipitation, on the shallow under the deep operation without mixing evenly, coating film thick...
Common problem of lacquer of waterborne woodwork: varnish besmear film is not level off, burnish is not even Phenomenon : Wood is filled with putty hole processing, after sealing the bottom, coating brush varnish, coating film flatness is low, luster is not uniform. Cause : Hole putty poor quality, loose, solvent absorption. The wood fiber and pith ray on the wood surface are relatively loose. The...
Baking performance of water-based glass paint - ask an expert for water-based paint. Question: I would like to ask about the water-based glass baking paint .Water has a boiling point of 100 degrees Celsius, so if you bake it at 140 degrees, it won't boil and bubble up and destroy the film. Right? Response: Water - based paint to balance the evaporation of water and film curing between the relation...
Water-based wood paint runs off oil---Ask a water paint expert Question: Waterborne wood lacquer should run oil to a rainy day only, or brush one day, also can run oil when waiting for the 2nd day to brush again, did especially ugly later . Water-based white paint does not have this problem. The problem ofwater-based varnish is obvious. Answer: Although it is a water-based paint, the film is hydro...

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 ...
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...
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...
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...
