1. Water-based polyurethane pressure-sensitive adhesive for its environmentally friendly non-polluting characteristics, the future will become the ultimate direction of development of pressure-sensitive adhesive; cost slightly higher than the acrylic, generally used for relatively high-end industries. 2. Solvent-based pressure-sensitive adhesive as a result of a v...
Introduction: Water-based adhesives to water as a dispersion medium adhesive, is a major category of environmentally friendly adhesives. The solvent-based adhesive is a homogeneous system with organic solvents such as benzene and toluene as the dispersion medium. The water-based adhesive is a heterogeneous system with water as the dispersion medium. Classification: Water as a disper...
September 1, 2018,Anhui sinograce Chemical Co., Ltd held an event launching ceremony of “The third Orange War”.
The Selection of good quality water-based adhesive not only help to improve the production efficiency, but also to protect the appearance of the product quality. Such as widely used in the field of self-adhesive water-based pressure-sensitive adhesive, such as water-based pressure-sensitive adhesive which is widely used in the field of stickers. This adhesive has many advantages, it is particularl...
Waterborne polyurethanes are mostly milky white. The whole process of waterborne polyurethane can be divided into two stages. The first stage is pre-stepwise polymerization, that is, the oligomeric diol, the chain extender, the water-based monomer and the diisocyanate are progressively polymerized through the solution to produce an aqueous polyurethane prepolymer having a molecular mass of the ord...
Some of the traditional glue in the adhesion of a great advantage is good adhesion, and the efficiency is very low, the most important thing is relatively low cost, most are someorganic materials. Relatively speaking,the biggest advantage of water-based adhesive is green, the traditional glue is inorganic materials, so it is not very environmentally friendly, pollution is relatively large, water-b...
Analysis on the application of waterborne polyurethane (WPU) in coatings Waterborne polyurethane is used in water based wood coatings, which is expected to obtain excellent film hardness, heat resistance and dielectric properties, and good film-forming properties. The higher the degree of microphase separation of aqueous polyurethane,the greater the difference of softening temperature, the better ...
water-based resin | water-based industrial coating (a) water paint common problems Water based paint common problem: bubble - big bubble Large bubbles are large, visible bubbles that are visible to the naked eye. Bulk bubbles generally occur during the production or application of water-based paints. Possible solutions: 1. Use appropriate defoaming agents In the process of producing water-based pa...
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...
Water - based wood paint common problems: gloss wood paint uneven luster Phenomenon There is light coating on the wood surface, coating film gloss, some areas of low gloss. Cause The wood fiber and pith ray in cork are loose with the growth of growth rings, the base material infiltrates excessively, the coating film increases the pigment volume concentration due to the decrease of the base ma...
How to solve the poor adhesion of water-based paint after soaking in water? Problems: water-based acrylic resin, self-drying system,60 ℃ / 120 minutes after the bubble row down into the water, can use fingernail.But after taking out to wait for water to be able again, how should solve? Response: This test method is still very harsh.General water - based resins, acrylic acid, polyurethane or Self-c...
Case study of water-based paint: the quality of water-based paint is unstable Maintaining the stability of waterborne coatings is one of the keys to the success of waterborne coatings manufacturers. This is especially important for manufacturers of industrial waterborne paints. There are many reasons for the unstable quality of water based paint, such as water-based paint process,water-based paint...
Asked by water-based paint experts: water-based wood lacquer wood grain display is not clear enough Question: Our company is now doing the first coat of wood lacquer and tried a water-based resin (polyurethane). and there is no problem with the adhesion.The current problem is that after adding color essence, it is applied to the floor and the wood grain display is not clear enough. The amount of t...
Water paint common problems: water paint viscosity deviation index The formulation and process of water based paint remain unchanged. However, the viscosity of the water based paint produced deviates from the index and is not within the control scope, for three reasons: 1.Water based paint raw material properties change. Changes such as filler particle size distribution, oil absorption volatile oi...
