Below the melting point, these waxes form a hard, white solid and above they form a clear liquid with a viscosity of about 100 cstks. Hard waxes have a narrow melting point (about 1-2☏). Genesee Polymers manufactures two general types of silicone waxes, hard waxes and soft waxes. For example, these waxes can be heated for the purpose of coating a part, then the wax will solidify and stay where it was applied. Silicone waxes are useful in a range of applications where lubrication is required and the solid/liquid transition is critical. Silicone waxes are unique because they have a much higher molecular weight and viscosity in the liquid state than do paraffin waxes. Silicone waxes are compatible with paraffin waxes and can be added to improve lubricity or to lower the surface tension. The resonance wavelength of each metal soap is shown in Table 6-16.ĮDTA is now used for rapid quantification, but this method cannot separately determine the different metal soaps in the mixed drier, and a simple qualitative method can also be used to determine the type of the drier.Silicone waxes behave like typical hydrocarbon waxes in that they undergo a phase transition from a solid to a viscous liquid over some well defined temperature range, usually slightly above room temperature.
In this case, the wavelength of the absorption spectrum of each element is different. The flame dissociates the chemical bonds of the metal soap and forms a floating cloud of each atomic component. The solvent, indicator and titration solution used in the EDTA titration method are determined by the metal type of the drier.Ītomic absorption spectroscopy is to heat the sample under the high temperature of the flame. The measurement method can be EDTA titration and atomic absorption spectrometry (A AS). The metal content of the drier The metal content of the drier must be measured correctly. Since it has no inorganic salts, it has good drying properties.
When the reaction is complete, the water is distilled off, filtered and adjusted for its metal content. The process is carried out under heating and refluxing of a mixture of organic acids, hydrocarbon solvents, water and fine metal powders. Under reducing conditions, metallic cobalt reacts directly with organic acids under thermal catalysis to produce metallic soap under oxidizing conditions.Ĭo+0.5O, +2RCOOH→→(R COO) 2Co+Hz O There is no sodium sulfate or sodium acetate silicone-modified wax in the reaction process, so there is no contamination by inorganic salts. Due to its good wetting properties, TEGOPREN 5840 spreads easily over the entire surface, ensuring clean and clear glass. It is particularly suitable for addition to spray polishes due to its non-streaking wetting effect.ģ, TEGOPREN 5840 has excellent anti-fogging properties and can be used to treat interior windshields in automobiles. 1, TEGOPREN 5840 has excellent malleability, low surface tension and can be diluted with water without affecting the surface properties.Ģ, TEGOPREN 5840 is distinguished by its excellent extensibility, can be diluted with water, and wipes off easily without leaving marks on the surface.
