Organotin catalysts – dibutyltin dilaurate

2021-11-23   Pageview:683

Dibutyltin dilaurate is a strong gel catalyst, which can be used in elastomers, adhesives, sealants, coatings, hard foam, molded foam, RIM, etc.

Dibutyltin dilaurate is also a kind of heat stabilizer, mainly used in the processing of PVC soft permeable products, silicone rubber catalyst, polyacrylate and phenolic resin light and heat stabilizer, etc.













Aluminum Dihydrogen Phosphate Aluminum Dihydrogen Phosphate is obtained by the reaction of phosphoric acid and aluminum hydroxide. It is a uniform and transparent liquid viscous liquid with a molecular formula of Al(Hz POi) s and a relative molecular mass of 318. Due to its high phosphorus content and high aluminum compound content, paraffin wax emulsion manufacturers aluminum dihydrogen phosphate not only has a significant flame retardant effect, but is also non-toxic. It does not produce dense smoke and poisonous gas when burned, and has no environmental pollution.

It also has strong chemical bonding and resistance. High temperature, good thermal stability, shock resistance, peeling resistance, etc. In addition to being used as a flame retardant, it can also be used as an inorganic binder due to its high bonding strength. Used in fireproof coatings, it mainly acts as a catalyst (acid source), flame retardant, and adhesive for the formation of the carbon-forming foam layer. The quality index of aluminum dihydrogen phosphate.
Phthalic anhydride Phthalic anhydride is a white flake or powdery solid with a molecular formula Ce He Og and a relative molecular mass of 148.12. It is easily soluble in ethanol. It is mainly used as an acid source and flame retardant in fire retardant coatings. Sometimes It is one of the components of the curing agent.

Formic acid, also known as formic acid, is a colorless, fuming and flammable liquid with a simple structure of H COOH and a relative molecular mass of 46.0248. It has a penetrating irritating odor and is soluble in water, ethanol and ether. It is highly corrosive and has a burn effect on the skin. It is mainly used as an acid source, catalyst and curing agent in fireproof coatings.

The explosion limit of formic acid is 18%~57%. It should be kept away from heat sources during storage and transportation, and should not be stored together with sulfuric acid and oxidants, and kept in a cool, dry and ventilated place.

The appearance of vegetable oleic acid is yellow oily liquid, structural formula Cz Haa COOH, relative molecular weight 282, insoluble in water, soluble in organic solvents such as ethanol and ether. If the storage temperature is below its freezing point, it will be semi-paste or even paste. Its quality refers to the most important point in the cup is the freezing point. Below 8°C, the lower the freezing point, the better. If the freezing point is high, the miscibility with the resin will be poor and segregation will occur, which will not provide lubrication. Oleic acid is mainly used as acid source, plasticizer and defoamer when used in fireproof coatings.

Ethanol Ethanol, also known as alcohol, has a simple structure of Cz H, OH, and a relative molecular mass of 46.07. It is a colorless, transparent, volatile, and flammable liquid. Please keep away from open flames when using and storing, and place it in a dark place with boiling point. At 78.4℃, the mixture of ethanol heat and air can form an explosive mixture, and the explosion limit is 3.5%~18.0%. Ethanol is soluble in water, methanol, ether, etc., and can form an azeotropic mixture with water.
