What Are The Commonly Used Polyurethane Metal Catalysts?

1. Mercury isooctanoate, mercury neodecanoate, and phenylmercury neodecanoate
(Neodecanoic acid-0) Phenylmercury, CAS No. 26545-49-3 Molecular formula: C16H24HgO2
2. Dibutyl tin dilaurate T12
12 is a new type of organic tin catalyst with high catalytic activity and does not contain 8 toxic organic tin compounds restricted by the European Union, such as dibutyltin and dioctyltin. It meets the EU pollution inspection standards:
T-12 can be used to replace traditional catalysts such as dibutyltin dilaurate and stannous octoate for polyurethane foam, coatings, adhesives and elastomers, with a wide range of applications.
3. Stannous octanoate T9
Stannous isooctanoate is a white or light yellow brown paste, sometimes referred to as stannous octanoate. Soluble in Shishanti, insoluble in water. It is the basic catalyst for the production of polyurethane foam, mainly used for the gelling reaction of polyurethane foam, and can also be used as an antioxidant for polyurethane foam. Used as a catalyst for polyurethane synthesis and room temperature vulcanization of silicone rubber. It is also used as a catalyst type curing agent for epoxy resin. During curing, the catalytic activity of stannous octanoate is greater than that of dibutyltin dilaurate. If the two are combined, the effect is better than when used alone, which can balance the reaction speed and curing speed. Due to the susceptibility of divalent tin compounds to oxidation and decomposition by oxygen and water vapor in the air, they must be used for nitrogen protection during storage and must be sealed to avoid high temperatures, high humidity, and reduced activity or failure.
4. Isooctanoic acid pliers
Isooctanoate is a kind of rare metal salt catalyst, which can be used as the auxiliary catalyst of tertiary amine to accelerate the reaction and curing of carbamate. Isooctanoate can be used to replace the tin metal catalyst in soft block foam, high-density soft foam, spray foam, microporous foam and hard foam system.
5. Zinc isooctanoate and zinc neodecanoate
Zinc isooctanoate can be used as polyurethane catalyst, which is mainly characterized by slow gel and good cross-linking catalyst, which can reduce the acidity of the system, accelerate the reaction and promote cross-linking and environmental protection, so it can be used to replace non environmental catalysts such as metal tin, lead, mercury, etc.: zinc isooctanoate is mainly used in polyurethane coatings, adhesives, elastomers, resins, and other industries
6. Lead Isooctanoate
Lead 2-ethylhexanoate is a chemical substance with the formula C16H30O4Pb. It is widely used as a drying agent in the paint and advanced color printing industries, as well as as as as a lubricant additive
Can be used in lead-free coatings: can be used in pigment systems where carbon black and iron red lose their drying due to adsorption of drying agents, to improve their drying phenomenon. Used in aluminum powder coatings, it has good floating stability and brightness.
