The full name of polyurethane foaming agent is one-component polyurethane foam jointing agent, commonly known as foaming agent, foaming glue, PU jointing agent, English PU FOAM is the product of aerosol technology and polyurethane foam technology cross combination. It is a special polyurethane product in which components such as polyurethane prepolymer, blowing agent, and catalyst are filled in a pressure-resistant aerosol can. When the material is sprayed from the aerosol tank, the foam-like po ...
waterproofing agentSilicone waterproofing agent is a new type of high-efficiency waterproofing material without pollution and irritation, which is widely used in advanced countries in the world. After this product is sprayed (or brushed) on the surface of the building, a colorless, transparent, UV-resistant, breathable film can be formed on the surface of the building, which is imperceptible to the naked eye. When rain blows on it or encounters moist air, the water droplets will be natural. Flow ...
Coupling agent is an important treatment agent with a wide range of applications, mainly used as an auxiliary agent for polymer composite materials. The biggest feature of the molecular structure of the coupling agent is that the molecule contains two groups with different chemical properties. Synthetic resins or other polymers undergo chemical reactions or generate hydrogen bonds to dissolve them. Therefore, coupling agents are called "molecular bridges" to improve the interface betwe ...

The Winter Solstice, also known as Nichinan Solstice, Winter Festival, and Asian Sui, has two connotations of nature and humanity. It is not only an important solar term in the twenty-four solar terms, but also a traditional Chinese folk ancestor worship festival. The winter solstice is one of the four o'clock and eight festivals. It is regarded as a big winter festival. In ancient people, there was a saying that "winter solstice is as big as a year". The customs of the winter solstice ...
Because there is relatively stable molecular structure Si-O-Si similar to inorganic acid salt in silicone polycondensate, no matter it is liquid, solid or elastomer polymer, it has high heat resistance and chemical stability. , Excellent electrical insulation and very good hydrophobicity.1) High temperature resistanceGenerally, the heat-resistant temperature of synthetic resin paint is below 150°C, while silicone paint can be used for a long time at 200°C. If high-temperature pigments are adde ...
Textile waterproofing agents are generally processed on textile fabrics or clothes. The specific methods of use are as follows: 1. Padding method: The waterproofing agent is formulated into working fluid, and the working fluid is passed through the rolling groove on the setting machine, dried, and shaped (the setting temperature is based on Fabrics of different materials have different temperature requirements); 2. Dipping method: mix the water-repellent agent into a working fluid in a certain p ...
Resin usually refers to an organic polymer that has a softening or melting range after being heated, and has a tendency to flow under the action of external force during softening. It is a solid, semi-solid, or liquid organic polymer at room temperature. In a broad definition, any polymer compound that can be used as a raw material for the processing of plastic products is called a resin.The relative molecular weight is uncertain but usually high. It is a solid, medium solid, pseudo-solid, and s ...
The application technology of silicone in coatings (including inks) has developed from professional, high-performance coatings to a wider range of fields. Through the application of silicone technology, the insulation, heat resistance, weather resistance, antifouling, abrasion resistance and other properties of the coating can be improved. The following is introduced according to its use.Insulation MaterialsThe first application technology of silicone resin as a coating was silicone resin-impreg ...
According to the chemical structure and composition of the coupling agent, it is divided into four categories: organic chromium complexes, silanes, titanates and aluminates:Folded chromium complex couplingAgent Chromium complex coupling agent was developed in the early 1950s. The metal chromium complex formed by unsaturated organic acid and trivalent chromium ion has mature synthesis and application technology and low cost, but the variety is relatively single.Folding titanate coupling agentAcco ...
