Environmentally friendly catalyst organic germanium organic zinc
Edit:Nantong Yutai Chemical Products Co., Ltd.   UpDate:2019-10-11

Environmentally friendly catalysts include organic and organic zinc

Typical characteristics of organic rhodium catalysts:

1. Safe and environmentally friendly, it can replace organic lead, mercury and tin in some applications;

2. Hydrolysis resistance is better than T9;

3. Promote NCO / OH reaction. In oily or waterborne polyurethanes, side reactions of water and NCO groups can be reduced to a certain extent and CO2 formation can be reduced.

The organic rhodium catalyst has good compatibility and can be used alone or in combination with other organometallic compounds.

Organic rhodium catalysts are used in all areas of the polyurethane industry, such as elastomers, coatings, foams, sealants, PU synthetic leather, shoe materials, runways, and the like.

Organic zinc properties

1. ZN content: 19%.


2, very effective cross-linking catalyst, the finished product surface is not sticky.

application:


As a slower gel and a better crosslinking catalyst, zinc can reduce the acidity of the system and accelerate the reaction to promote crosslinking.

The user can adjust the gel state by changing the concentration of the two metals in the system. For example, by adding zinc in the organic zinc system, the operation time in the kettle during the induction period is prolonged, and post-cure is promoted. Due to the different reaction systems of the users, the optimum zinc bismuth is not the same. Keep the amount of bismuth unchanged, add different amounts of zinc to test, control the proportion of bismuth zinc between 1:1 and 1:10, find the best 铋-zinc ratio for your system.
