    摘要: The present invention relates to a monocarboxylic acid based antifreeze coolant formulation for applications such as for gasoline engines which may be used for inhibition and prevention erosion and corrosion of aluminum and the corrosion of other metals exposed to an aqueous liquid in automotive coolant systems. The formulation further inhibits mineral scale. It may be packaged as an ethylene glycol based additive for use in new engines or in a concentrated inhibition package as an additive as for reinhibition of used coolant. The combination of a mixture of ethylene or propylene glycol, a monobasic carboxylic organic acid, azoles, and low levels of molybdates provides corrosion resistance. A heavy duty formula more suited for diesel engines also contains a nitrite salt and/or nitrate salt and a siloxane stabilized silicate, and combinations thereof to provide a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids reducing the corrosion rate and is effective at relatively low concentrations varying pH ranges.

    摘要: The invention relates to unsaturated polyester resins with higher molecular weight, low viscosity and high solubility specially in reactive diluents. The invention also relates to a method for manufacture of such unsaturated polyester resins and to use thereof in various applications such as gelcoats. The unsaturated polyester resin comprises 20-85 wt.% of at least one unsaturated polyester having a molecular weight of 2000-6000, prepared from 1) 30-70 mol%, preferably 40-60 mol% of at least two unsaturated carboxylic acids or derivatives thereof and at least one of them is an unsaturated aromatic carboxylic acid or a derivative thereof and optionally of one or more carboxylic acids and derivatives thereof, 2) 30-70 mol%, preferably 40-60 mol% of at least two diols and at least one of them is an aliphatic branched diol, preferably 2,2,4-trimethyl-1,3-pentanediol and/or 2-butyl-2-ethyl-1,3-propanediol and the amount of the aliphatic branched diol/diols is 0.5-8 mol%, preferably 2-6 mol%, 3) 0.5-10 mol%, preferably 2-6 mol% of at least one monoalcohol, 4) optionally a modifying chemical/chemicals and the total amount of monoalcohols and modifying chemicals is 0.5-20 mol%, preferably 1-15 mol%, 5) optionally 0.5-20 mol%, preferably 1-10 mol% of a polyhydric alcohol/alcohols having at least three hydroxyl groups, and 15-50 wt.% of at least one reactive diluent.

    摘要: Vinyl ester resins processed until low epoxy values are reached, are storage stable for two weeks at 54 DEG C (130 DEG F). Adding a copper salt inhibitor also provides two weeks storage stability at 54 DEG C (130 DEG F). A synergistic effect is observed if both low epoxy values are reached and copper naphthenate inhibitor is used, extending shelf life stability to two months at 54 DEG C (130 DEG F).
