Introduction to the functional characteristics of commonly used polyurethane metal catalysts

1, Bismuth isooctanoate, bismuth neodecanoate
Bismuth isooctanoate is a bismuth metal carboxylate catalyst that can be used as an auxiliary catalyst for tertiary amines to accelerate the reaction and curing of urethane; bismuth isooctanoate It can be used to replace tin metal catalysts in flexible block foam, high-density flexible foam, spray foam, microcellular foam and rigid foam systems.
2. Zinc isooctanoate, zinc neodecanoate
Zinc isooctanoate can be used as a polyurethane catalyst. Its main features are slower gelation and better cross-linking catalyst. It can reduce the acidity of the system, accelerate the reaction and promote cross-linking. Environmentally friendly, it can be used to replace non-environmentally friendly catalysts such as metal tin, lead, and mercury; zinc isooctanoate is mainly used in polyurethane coatings, adhesives, elastomers, resins and other industries
3, Lead isooctanoate
Lead 2-ethylhexanoate is a chemical substance with the chemical formula C16H30O4Pb. It is widely used as a drier in the paint and advanced color printing industries, and also used as a lubricant additive
4. Mercury isooctanoate, mercury neodecanoate, phenylmercury neodecanoate
(Neodecanoate-O)phenylmercury, CAS number: 26545-49-3 Molecular formula: C16H24HgO2
5,Dibutyltin dilaurate T-12
T-12 is a new type of organotin catalyst with high catalytic activity and does not contain 8 toxic organotin compounds such as dibutyltin and dioctyltin that are restricted by the EU. Comply with EU pollution inspection standards;
T-12 can be used to replace traditional catalysts such as dibutyltin dilaurate and stannous octoate in polyurethane foams, coatings, adhesives and elastomers, with a wide range of applications.
6,Stannous octoate T-9
Stannous octoate is a white or light yellowish brown paste, sometimes called stannous octoate. Soluble in petroleum ether, insoluble in water. It is the basic catalyst for the production of polyurethane foam. It is mainly used for the gelation reaction during polyether-polyurethane foaming. It can also be used as an anti-aging agent for urethane 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, stannous octoate has greater catalytic activity than dibutyltin dilaurate. If the two are used in combination, the effect is better than when used alone, and both reaction speed and curing speed can be taken into account. Since divalent tin compounds are easily oxidized and decomposed by oxygen and water vapor in the air, they must be protected by nitrogen during storage and must be sealed to avoid high temperatures and excessive humidity to prevent activity decline or failure.
7, zirconium isooctanoate
Can be used in lead-free paints; can be used in pigment systems such as carbon black and iron red that lose drying due to adsorption of driers to improve the drying phenomenon; and can be used in aluminum paints Medium, with good floating stability and brightness.
8, cobalt isooctanoate
In various air-drying paints, it is used as a paint drier and as a curing accelerator for unsaturated polyester resin adhesives. Cobalt isooctanoate solution (Co2+ Content 12%)3.5% and styrene 96.5% are formulated as No. III accelerator. Used as catalyst in two-component polyurethane paint; used as plastic stabilizer; preservative; organic synthesis of phenylacetic acid, acetophenone, etc.
9, Nickel isooctanoate
Used as a general drier and as a catalyst in high-grade inks. It can also be used as grinding dispersant, UV absorber, etc.
10, lithium isooctanoate
Alias: 2-ethylhexyllithium, lithium 2-ethylhexanoate, 6-heptynenitrile, lithium isooctanoate, lithium 2-ethylhexoxide, 2- Lithium ethyl-1-hexanoate. CAS number 15590-62-2
11, Potassium isooctanoate
Mainly used as salt-forming agent for the synthesis of cephalosporin antibiotics, cross-linking agent for polymer materials, heat stabilizer for plastic products, catalyst for polymerization reaction, lubricating oil and fuel oil of additives. In the polymerization process of polyester resin, it promotes cobalt soap catalysis and effectively reduces the amount of cobalt; it can also be used to make dyes, spices, preservatives, etc.
12, rare earth isooctanoate
13, calcium isooctanoate
Usage: in various air-drying paints.
14, Antimony isooctanoate
It is widely used in PVC color masterbatch, PVC rigid and extruded PVC products. It can partially replace organotin heat stabilizer. When compounded with calcium stearate, the thermal stability of this product is better than that of calcium-zinc composite heat stabilizer. .
15, lanthanum isooctanoate
Plastic industry additives, paint and pigment driers, coating dispersants.
