Dibutyl tin diacetate

The pieces of cloth are then plied up and moulded at about 170°C for 30-60 minutes. Whilst flat sheets are moulded in a press at about lOOOlbf/in (7 MPa) pressure, complex shapes may be moulded by rubber bag or similar techniques at much lower pressures ( 15 Ibf/in ) (0.1 MPa) if the correct choice of resin is made. A number of curing catalysts have been used, including triethanolamine, zinc octoate and dibutyl tin diacetate. The laminates are then given a further prolonged curing period in order to develop the most desirable properties. 

High purity and high molecular weight siloxane-urea/urethane copolymers, (1), were prepared by Kuepfer [ 1] at ambient temperature using dibutyl tin diacetate as catalyst under anhydrous conditions. Additional siloxane-urea/urethane copolymer derivatives were prepared by Schafer [2].

The available remaining isocyanate may then react with a tertiary alcohol when dibutyl tin diacetate is used as catalyst. An interesting diol containing both primary and tertiary terminals is hydroxycitronellol, a derivative of natural products ...

Tin oxide films have been deposited onto soda-lime-silica glasses in a cold-wall reactor at substrate temperatures between 350°C and 490°C [108]. The mechanism of formation was carefully studied using four different tin alkyls as starting compounds namely dibutyl tin diacetate (DTD), tetrabutyl tin (TBT), tetraethyl tin (TET) and tetramethyl tin (TMT). The investigations showed for the mechanism a dependence on the molecular structure and reactivity of the initial tin compound to oxygen. The influence of substrate temperature on deposition rate (Arrhenius plots) showed three characteristic regions for which three processes were proposed [108] ... 

Bis(4 -hydroxyphenyl)valeric acid and 3 drops of dibutyl tin diacetate are placed in a dry standard apparatus with mechanical stirrer connected to a vacuum line. The polycondensation is carried out in two steps in order to obtain high conversion and high molar mass First, the monomer is stirred in a nitrogen stream for 70 min at 200°C during this time period an increase in viscosity of the melt should be observed. After that, vacuum is applied at 225°C for 3 h with stirring and then for 1 h without stirring until a final vacuum of 0.010 mbar is reached. The crude product is dissolved twice in approximately 100-150 ml THF and precipitated into 500 ml water. After filtration the product is dried over phosphorus pentaoxide for several days. 

The oligomer solution is then catalyzed by triethanol amine, metal octoates, or dibutyl tin diacetate and heated to increase the viscosity. At this point, it is cooled and can be stored until used. These silicone oligomers are used to make glass fabric laminates and reinforced molding powders. Phenyl silicon is compatible with epoxy, aUcyd, urea, melamine, and phenolic resins and may be blended with them to increase their resistance to heat, flame, water, and weather.

Some silicone adhesives and sealants require condensation catalysts to accelerate curing. These are usually organotin and organotitanimn compounds such as dibutyl tin dilamate, dibutyl tin diacetate, dibutyl tin dioctoate, or tetrabutyl titanate.
