Most commercial synthetic elastomers lack adhesion, either to themselves or to other surfaces. Therefore, in order to increase their adhesion, tackifiers are added. In modern industrial production, organic component materials(such as silicone) are attracting attention for their unique properties and wide range of applications. So what are silicone tackifiers?
Tackifier is a chemical that increases the viscosity in water or other solutions, thus enhancing their sticking properties. The main role of the tackifier is to improve the product properties, can promote adhesion, viscosity, stability, and so on.
Silicone tackifiers are silicone polymers with organic groups, between a variety of polymer materials to play a bonding role in the additives, through the interaction with other polymer materials, can increase the material viscosity and adhesion properties, and can be used for a variety of adhesives and sealing materials preparation. Compared with inorganic silicon, it also has good high-temperature resistance, waterproof performance chemical resistance, and thermal stability, and has a wide range of applications in hot melt adhesives, pressure-sensitive adhesives, and other fields.

1. What is the mechanism of silicone tackifiers?
The mechanism of the silicone tackifier is mainly realized by changing the fluidity and surface tension of the liquid. Silicone tackifier molecules contain silicone-oxygen bonds, its oxygen atoms and silicon atoms make it have strong stability and high-temperature resistance and can be in a variety of environments to maintain its tackifying effect. When the silicone tackifier is added to the liquid, its molecules will interact with the liquid molecules to form a layer of material similar to the mesh structure, thus increasing the viscosity and stickiness of the liquid. At the same time, a silicone tackifier can also reduce the surface tension of the liquid, so that it is easier to adhere to the surface of the object to improve the bonding properties.
2. How to classify silicone tackifiers?
According to their chemical structure, silicone tackifiers are also liquid or solid polymer, can be divided into the following categories:
(1) Silicone rubbers tackifiers
Silicone rubber is a flexible and elastic synthetic material, commonly used in sealing, insulation, and medical fields. Adding an appropriate amount of silicone tackifier in silicone rubber can significantly improve its adhesive strength with a variety of materials in natural and synthetic sources.
(2) Silicone resin tackifier
Silicone resin is a polymer synthetic material with excellent electrical insulation, weather resistance, and high-temperature resistance. By adding a silicone tackifier to silicone resin, the adhesion of products (such as hot melt adhesives, and pressure-sensitive adhesives) to various substrates can be effectively improved.
XJY-8207S/M Hydrogen MQ Resin can be used as a tackifier in sealants and silicone resin coatings.
(3) Silicone oil tackifier
Silicone oil is a class of compounds with silicone as the basic structure, with excellent lubricating properties and chemical stability. Adding a certain amount of silicone tackifier to silicone oil can enhance its wettability and adhesion to various polymers.
XJY 705 184.108.40.206-Tetramethylcyclotetrasiloxane(D4H) is a kind of reactive silicone containing silicone-hydrogen bonding, which can react with unsaturated olefins by addition. It can be used to prepare synthetic specialty tackifiers.
