Are organic bismuth catalysts being used on runways?

Recently, the "toxic plastic runway" incidents occurred frequently in Jiangsu and other places. Relevant departments found that the runway was littered with toxic residues after construction. Pupils' resistance was poor, and they would travel with dizziness, nosebleeds and other symptoms, seriously endangering students' health. How to ban the "poison track" and make it a green playground for students, we should strictly control each kind of raw materials, including catalysts. The organic bismuth catalyst is introduced, which does not contain cadmium, lead, mercury, chromium and other heavy metals. The addition amount is 0.04% - 0.08%. It can completely replace the commonly used organic Pb/Hg, Pb/Zn and other heavy metal composite catalysts. It can not only meet the requirements of on-site construction technology, but also eliminate Pb and Hg pollution in the production and use of polyurethane plastic runway materials. It is an ideal raw material for plastic runway. Many engineering teams are using our product and have received positive feedback.

Organic bismuth Valikat 2010, a special catalyst for polyurethane runway

Product parameters: product density: 1100-1200kg/m3 Ignition point: 110 ℃ Metal content: 19.3-20.7% Color: light yellow liquid

Product characteristics: This product is specially developed for polyurethane runway materials. It is an effective choice to ban "toxic plastic runway". The product does not contain heavy metals restricted by Europe and the United States. The product has the following characteristics:

(1) The performance of runway materials is better. Compared with lead, the hardness can be increased by 2-6A, and the tensile strength, tear strength, elongation and other indicators can be increased by 10% - 25%. Therefore, the usage of TDI (MDI) and MOCA can be saved more.

(2) Higher runway performance. The product does not contain cadmium, lead, mercury, chromium and other heavy metals. It can not only meet the requirements of on-site construction technology, but also eliminate Pb and Hg pollution in the production and use of polyurethane plastic runway materials. The runway can meet the very strict American and European standards and can be exported completely.

(3) The runway is easy to operate. It is added directly without affecting the construction and process.

(4) The runway is cost-effective. The addition amount of 0.4-0.8% is cheaper than mercury and rare earth catalysts.

(5) The runway is tasteless. The smell is mostly caused by incomplete reaction, and whether the reaction is complete depends on the correct choice of catalyst. Valikat Bi2010 reaction is more effective, so the smell is smaller or odorless. After curing, even if the glue liquid of TDI raw material is used, it has no taste, is safe, and reduces or eliminates the hazards of constructors and users.

(6) Organic bismuth catalyst improves the aging resistance of runway. Compared with lead, the durability of runway color is better, and the aging resistance is improved by 15% - 30%
