Product information
Product description
Structural formula:
Empirical formula:C32H64O4Sn
Molecular weight:631.56
CAS No.:77-58-7
Chemical name:Dibutyltindilaurate
Properties
D-80 is a colorless to yellow liquid, low-temperature white crystals. D-80 soluble in the most common ,such as benzene, toluene, ethanol, acetone, ethyl acetate, chloroform, carbon tetrachloride, benzene, ethanol, petroleum ether and other solvents and various industrial plasticizers, D-80 is insoluble in water.
Promotes rapid gelation and tack-free times.
Improves mechanical properties in molded and slabstock foams.
Technical data
Reactivity
D-80 is very stable in aqueous solution, but in alkaline solution at room temperature, hydrolysis.
Application and performance
Catalyst for RTV
D-80 used as a catalyst in the vulcanizing cure of silicones at room temperatures.
Polyurethane
D80 catalyst finds greatest use in the manufacture of rigid polyurethane foams. In demanding applications where amine catalysis alone is inadequate, the extra activity obtained by the synergistic combination of organometallics like D-80 catalyst with an amine catalyst permits the required rapid catalysis. Examples include high-density structural foam, sprayup wall insulation and rigid boardstock run at high line speeds. Even when used at levels as low as 0.1 phr based on polyol, D-80 catalyst is especially effective
in promoting rapid gel and tack-free times.
Tetravalent diorganotins like D-80 catalyst are known throughout the industry as promoters of the reaction of isocyanates with polyols to form polyurethanes, and of the secondary crosslinking reactions to form allophonate and biuret linkages.
Thermoplastics
The grafted polyethylene can then be immediately crosslinked in the presence of a tin catalyst.
Other applications
Polyamide and phenolic resins, light and heat stabilizers.
Product safety, handling and storage
Customers considering the use of this product should review the latest Material Safety Data Sheet and label for product safety information, handling instructions, personal protective equipment if necessary, and any special storage condition required. The “Best use before end” date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily
mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
Packaging
