The oil-based glue defoamer is made of ether, fatty alcohol and multiple active additives through a special process. It is easy to disperse in water-based system, has strong self-emulsification, good defoaming, long-lasting foam suppression, and has special effects on water-soluble polymers and medium and low viscosity systems. It is especially suitable for latex-type water such as styrene-acrylic, ethylene-propylene, pure acrylic, vinyl acetate emulsion, and carboxylated styrene butadiene. It h ...

Background technique:The existing silicone surfactants used to prepare polyurethane rigid foams all use hydrogen-containing silicone oil and allyl alcohol as the initiator, and the allyl polyether reaction of the alkylation reaction of ethylene oxide and propylene oxide The allyl polyether, which is usually used to prepare the silicone surfactant of polyurethane rigid foam, is an unblocked polyether.Although the acetyl-terminated allyl polyether has a high end-capping rate, some products can rea ...

High resilience liquid silica gel is a kind of silica gel with better resilience. Because liquid silica gel is safe and environmentally friendly, it can fully meet the requirements of food grade. It can be used for baby products, such as baby pacifiers. High resilience liquid silica gel has good flow properties and fast vulcanization., Fast molding speed, yellowing resistance, heat aging resistance, excellent tear strength and other advantages, and easy to use, so it has a wide range of uses, su ...

Silicone resin is a highly cross-linked polyorganosiloxane with a network structure, usually methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane, diphenyldichlorosilane or methylbenzene Various mixtures of dichlorosilanes, in the presence of organic solvents such as toluene, are hydrolyzed at lower temperatures to obtain acid hydrolysates. The initial product of the hydrolysis is a mixture of cyclic, linear and cross-linked polymers, usually containing a considerable number of h ...

OrganicThere are two main types of silicone resin paint, one type is low molecularSilicone-based silicone resin paint, the other type is modifiedSilicone resin paint.Silicone resin paint has heat resistance, weather resistance,Ozone resistance and resistance to ultraviolet rays in sunlight, its gloss retention and resistanceThe pigment has good powdering properties and excellent electrical insulation. It ...

In the formulation, the main functions of surfactants are: one is to improve the emulsifying ability between the components, so that they can be more effectively mixed with each other; the other is to control the system to have proper surface tension during the foaming process to produce good Bubble network structure, therefore, can also be called foam stabilizer. Polyester and polyether flexible foam have different raw material bases and different properties. Therefore, the selection and dosage ...

General resin refers to an organic structure that can soften or flow after heating, and is mostly semi-solid and solid at room temperature. Broadly speaking, resin can refer to all macromolecules processed by plastics, especially chemicals. Resin itself is also one of the raw materials for manufacturing plastics. It can be said that the application of resin is very wide. The silicone resin mentioned by the editor here refers to a very special kind of resin, also called a highly cross-linked mixt ...

For non-chemical professionals, this term is too unfamiliar. Will it exist in our lives and is closely related to life? The stickers, label paper, and even the adhesive part behind the aunt’s towel in our homes are all Cannot do without "silicone release agent". Now, the silicone manufacturer Xin Jiayi will take you to understand what a silicone release agent is.Release agent, also known as release agent, is used between the substrate and the pressure-sensitive adhesive layer. Its mai ...

With the rapid development of industry in our country, the use of defoamers has become more and more widespread, but many people only know that defoamers are mainly used to eliminate foam, but have not deeply understood the working principle of defoamers. Today I will introduce to you the working principle of defoamer.One, defoamer ingredientsWe all know that to understand the working principle of a product, we must first know the composition or structure of the product. First, let's take a look ...
