Anhui sinograce Chemical Co., Ltd.participated in the 20th China International Adhesive and Sealant Exhibition in 2017 and get complete success. Sinograce Chemical as a well-known brand in water-based products industry, participated in this event. The exhibition focused on the display of water-based acrylic adhesive and special modified acrylic adhesive. In the three...
The method to determine whether the quality of the seal printing tape is poor: Ordinary sealing tape glue is acrylic glue, also known as pressure-sensitive adhesive, the main component is tincture. Tincture is a kind of macromolecular active substance. The activity will be affected by the level of temperature. Tincture content of glue will directly affect the use of tape. Some individuals thi...
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...
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...
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...
Asked by water-based paint experts: water-based paints appear flocculated in the production process Problem: Our company produced a batch of waterborne paint last week. The formula remains unchanged. After the completion of production, the coating appears a mass flocculent,it is difficult to remove the filtration, the quality of waterborne coating is reduced. What is the cause? What method c...
How to solve the water - based acrylic paint back adhesion problem? - ask a water-based paint expert Problem: How to solve the water - based acrylic paint back adhesion problem? Water - based acrylic paint back adhesion is a problem often encountered by water - based paint formulators.In order to solve the problem of water - based acrylic paint adhesion, we must fundamentally unders...
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...
Formulation design system for waterborne coatings - film forming AIDS The polymer constituting the emulsion or dispersion generally has a glass transition temperature higher than room temperature. In order for the emulsion particles to be well fused into a uniform paint film, it is necessary to reduce the minimum film formation temperature (MFFT) of the crystallization aid.Film form...

Plastics are classified into two types: thermosetting and thermoplastic.Among them, thermosetting plastics have high cross-linking density, good solvent resistance and heat resistance, relatively high surface polarity, and wide range of coatings available.For example, unsaturated polyester is called polyester fiberglass. The texture is hard and polar, and there are many coatings that can be used. ...
Current problems with waterborne polyurethane adhesives: (1) Low solid content: At present, the solid content of water-based polyurethane (WPU) can reach 45%. Fewer systems lead to higher drying and transportation costs. Increasing the solid content leads to an increase in the viscosity of the system, which makes emulsification and dispersion difficult. Reduced emulsion stability. (2) Slow drying ...
Composition of water bases adhesive 1.adhesive: also known as adhesive agent, after the surface treatment of two or more adhesive materials firmly connected together, and has a certain mechanical strength of chemical properties, such as epoxy resin phosphate copper oxide white latex. 2.Solid material (base material): determines the main physical, chemical and mechanical properties of rubber joints...
1.Principles of adhesive selection Consider the type, nature and hardness of the bonding material Consider the shape, structure and process conditions of the bonding material Consider the load and form (tensile force, shear force, peel force, etc.) borne by the bonding part; consider the special requirements of materials such as high temperature and low temperature resistance. 2.Properties of bond...
