Hydrogenated resin manufacturer

Hydrogenated resin is a type of resin that has undergone hydrogenation modification treatment and has various excellent properties. Its principle mainly involves hydrogenation reaction. The following is a detailed explanation of its principle by hydrogenated resin manufacturer:

1. Purpose of hydrogenation

The main purpose of hydrogenated resin is to improve certain properties of the resin through hydrogenation reactions. Specifically, hydrogenation reaction can saturate unsaturated bonds (such as carbon carbon double bonds) in resin molecules, thereby improving the weather resistance, yellowing resistance, stability, and other properties of the resin.

2. Hydrogenation process

During the hydrogenation process, resin reacts with hydrogen gas under the action of a catalyst. The selection of catalyst is crucial for the efficiency of hydrogenation reaction and the performance of the product. Common catalysts include precious metal catalysts such as nickel, palladium, platinum, as well as certain non precious metal catalysts.

During the reaction process, hydrogen molecules are adsorbed on the catalyst surface and dissociated into hydrogen atoms. These hydrogen atoms then undergo addition reactions with unsaturated bonds in the resin molecules, forming saturated C-C bonds. This reaction process makes the unsaturated parts in the resin molecules more stable, thereby improving the overall performance of the resin.

3. Hydrogenation type

Hydrogenated resin can be applied to various types of resins, such as epoxy resin, C5 petroleum resin, etc. The performance improvement of different types of resins after hydrogenation may vary, but the basic principle is to saturate unsaturated bonds through hydrogenation reaction.

For example, hydrogenated bisphenol A epoxy resin saturates the unsaturated bonds in bisphenol A epoxy resin through hydrogenation reaction, thereby improving its weather resistance and yellowing resistance. This resin has low viscosity, long gel time and good weather resistance, and is usually used in applications requiring high heat resistance and solvent resistance.

4. Hydrogenation effect

Hydrogenated resins typically exhibit significant improvements in performance. In addition to improvements in weather resistance, yellowing resistance, and stability, hydrogenated resins may also have better environmental friendliness, adhesion, and compatibility. These performance improvements make hydrogenated resins widely used in various fields such as coatings, rubber, adhesives, inks, etc.
In summary, the principle of hydrogenated resin is to saturate the unsaturated bonds in the resin molecules through hydrogenation reaction, thereby improving its properties. This process requires the selection of appropriate catalysts and reaction conditions to ensure the efficiency of the hydrogenation reaction and the performance of the products.
