Converge Polyol 212-10

Converge Polyol 212-10 in DBE Solution is a 1000 molecular weight polymer produced from propylene oxide and carbon dioxide blended with dibasic ester. Converge polyol 212-10 is an amorphous, linear, aliphatic polycarbonate diol. Carbon dioxide accounts for approximately 40% of the polyol mass. Converge polyol 212-10 in DBE is a viscosity optimized blend for a variety of polyurethane systems. It can be used in the preparation of adhesives, foams, coatings, elastomers and TPUs.The aliphatic polycarbonate backbone delivers unique high performance to polyurethanes in terms of both strength and environmental resistance. In adhesive applications, it provides improved adhesive & cohesive strength and hydrolytic stability. In coatings, it delivers UV resistance and high hardness.It substantially increases the load bearing, tensile, and tear strength of flexible foams. Converge polyol 212-10 can also improve abrasion resistance.Converge polyol 212-10 in DBE can be utilized in existing urethane systems. The optimized blend allows for flowability at ambient conditions.It has excellent compatibility with polyester polyols and isocyanates. Compatibility with polyether polyols is low to moderate; it is recommended that polyether-based systems are cured shortly after polyol blending.Converge polyol 212-10 in DBE is compatible with standard chain extenders, surfactants, and catalysts.

Di-t-Butyl Dicarbonate

Di-t-butyl dicarbonate is a reagent widely used in organic synthesis. This carbonate ester reacts with amines to give N-tert-butoxycarbonyl or so-called t-BOC derivatives. These derivatives do not behave as amines, which allows certain subsequent transformations to occur that would have otherwise affected the amine functional group. The t-BOC can later be removed from the amine using acids. Thus, t-BOC serves as a protective group, for instance in solid phase peptide synthesis. It is unreactive to most bases and nucleophiles, allowing for an orthogonal Fmoc protection.

Dichlorodimethylsilane

Dimethyldichlorosilane is a tetrahedral, organosilicon compound. It is made on an industrial scale as the principal precursor to dimethylsilicone and polysilane compounds. It can be used as a coating on glass to avoid the adsorption of micro-particles.

Dichloroethylene, 1,1-

1,1-Dichloroethene, commonly called 1,1-dichloroethylene or 1,1-DCE, is an organochloride . It is a colorless liquid with a sharp odor. Like most chlorocarbons, it is poorly soluble in water, but soluble in organic solvents. 1,1-DCE was the precursor to the original cling-wrap for food, but this application has been phased out.1,1-DCE is mainly used as a comonomer in the polymerization of vinyl chloride, acrylonitrile, and acrylates. It is also used in semiconductor device fabrication for growing high purity silicon dioxide (SiO2) films.

Properties
Dimethyl Stearyl Amine

Dimethyl stearyl amine is used as an intermediate for the manufacture of quaternary ammonium compounds, amine oxide and betaine surfactants for personal care, and institutional use. It is used as a corrosion inhibitor and acid-stable emulsifier.
