Factors affecting paint recoating and how to solve the problem of recoating
There are many factors that affect the recoating of coatings, mainly including the following categories. The first one is the influence of additives. Like some silicon-based additives, such as defoamers for organosilicon, leveling agents for organosilicon, and some wax powders and pastes, they ma...Read more -
The causes of shrinkage in paint film and how to solve the shrinkage problem
Shrinkage is the most common paint film defect in coatings, which refers to the phenomenon of shrinkage in the local coating area, and then the exposed or partially exposed back coating surface, forming pits and pockmarks, including shrinkage, pumping, as well as pockmarks, pockmarks, fish eyes, ...Read more -
Types, performance characteristics, and applications of defoamers
When introducing the principle of defoamers, the first is incompatibility, and the second is that they have a lower surface tension than the system being used. So all substances that are incompatible with the application system and have lower surface tension than the applied system can be used as...Read more -
Types, characteristics/applications of substrate wetting agents
Only when the surface tension of the coating is lower than that of the substrate, can the coating complete the spreading and wetting process. In water-based coatings, the surface tension of water is relatively high, far exceeding that of various common substrates. So water-based coatings, especia...Read more -
How to improve drying speed, single component water-based
Many of our friends make water-based light anti-corrosive paint. They will use some acrylic lotion. They always hope that the surface will be dry and the actual work will be done as soon as possible. How to achieve the goal of quick drying? Usually, I think there are several aspects to consider. ...Read more -
Polarity of dispersants and compatibility of coating systems
Dispersants achieve stability through electrostatic stabilization or steric hindrance. The two basic requirements for stable steric hindrance are that the anchoring group has sufficient adsorption force on the pigment, and the solvation chain segment, also known as steric hindrance steric hindran...Read more -
Types, structural characteristics, and applications of dispersants
There are many types of dispersants used in industrial coatings. Substances that can wet and stabilize pigments can be used as dispersants, with at least 1000 or more. It has a dispersing effect. According to its structure, we can roughly divide it into the following three categories. The first c...Read more -
Precautions for using defoamers
Defoamers use the principle of incompatibility and ground surface tension to achieve defoaming effects. If an additive is compatible with the system being used, it is usually stable in foaming. Only when it is incompatible can it have the effect of defoaming. However, excessive incompatibility ca...Read more -
CB type acrylic building sealant and its application
Abstract: This sealant is made of pure acrylic acid lotion with high flexibility, high stability and excellent weather resistance as the core film forming base material, together with functional additives and inorganic filling system. It is different from traditional styrene acrylic lotion sealan...Read more -
Acrylic lotion used for low temperature water-based building sealant
Abstract: Conventional water-borne acrylic lotion building sealant is widely used in the field of building joint sealing due to its advantages of green environment protection, convenient construction, wide range of bonding substrates, and outstanding cost performance. However, pure acrylic acid a...Read more -
Study on Synthesis and Application of High Solid and Low Viscosity Styrene acrylic lotion for Corrugated Carton Flexographic Ink Printing
Abstract: Flexographic printing on corrugated cardboard boxes is one of the most widely used and industrialized printing processes in the packaging printing industry. It has the advantages of low plate making cost, low printing pressure, wide substrate adaptability, and high production efficiency...Read more -
Construction of self crosslinking core-shell acrylic acid lotion and its effect on water-based ink
Abstract: The printability, film forming quality and post-treatment performance of flexographic water-based ink mainly depend on the microstructure and film forming mechanism of the polymer binder. Conventional homogeneous acrylic lotion has common defects such as poor ink film density, insuffici...Read more
