This work builds on our previous experience of blending and co-curing an unsaturated polyester resin with other relatively inexpensive, but more flame retardant resins such as chemically modified phenolic resins, and extends this technology to the almost equally flammable vinyl ester resins, commonly ...
The resin’s superb solubility in pure ester is particularly impressive, resulting in a clear, colorless solution without the use of ketones. wacker.com 这种羰基表涂树脂的独特之 处首先在于它 在纯 酯中 具 有优 异的可溶性, 因此, 不需要任何酮类便可制成无色透明的溶液, 除应用灵活的特点外, ...
4.5. Chemical structure of bisphenol-A vinyl ester Vinyl ester production begins by pumping the requisite epoxy resin into a reactor vessel, as shown diagrammatically in Fig. 4.6, after which a stoichiometric quantity of methacrylic acid is added, prior to raising the temperature. This causes the...
This resin is suitable for storage in a dark and dry place with a temperature between 5 ºC and 30 ºC. The storage period may be shortened at higher temperatures and may lead to changes in resin properties. The storage period of Vinyl ester resin resin containing styrene ...
6. The resin blend of claim 1 in which the acid compatibilizing agent (c) is a strong acid having a pKa in water of less than about 1. 7. The resin blend of claim 6 in which the acid compatibilizing agent (c) is aryl sulfonic acid, an alkyl ester of sulfuric acid, picric ac...
The resin should be stored in a dark and dry place in original unopened and undamaged packaging at temperatures between 5°C and 30°C. Shelf life is reduced at higher temperatures and the properties of the resin might change during storag...
vinyl pentanoate, vinyl hexanoate, vinyl heptanoate, and vinyl octanoate and higher alkanoates may be used. Vinyl acetate is preferred. Related compounds having the polymerizable double bond in the acid moiety of the ester such as methyl methacrylate, methyl acrylate, ethyl acrylate may also be ...
Because EVA resin blended foam products have properties such as softness, good elasticity, and resistance to chemical corrosion, they are widely used in soles and interior materials of mid-to-high-end travel shoes, hiking shoes, slippers, and sandals. 6. The m...
