International Classification:
C09K 5000
US Classification:
252 76
Abstract:
This invention relates to single-phase antifreeze and coolant concentrates comprising an alcohol, a metal salt of a carboxysiloxane and an organic basic PH buffer and corrosion inhibitor comprising a hydroxybenzoic acid or mixtures thereof. The concentrates are preferably used as coolants either undiluted or upon dilution with about 25 to about 90 percent by weight of water based upon the total weight of the concentrate. The alcohol is preferably ethylene glycol. The coolant compositions are effective in providing protection against corrosion of all metals and alloys used in industrial heat exchangers and are especially effective in inhibiting the corrosion of aluminum internal combustion engine and radiator components.

US Classification:
252 76
Abstract:
This invention relates to single-phase antifreeze or coolant concentrates comprising an alcohol, a silicone-silicate copolymer and an organic basic pH buffer and corrosion inhibitor comprising a hydroxybenzoic acid or mixtures thereof. The concentrates are preferably used as coolants either undiluted or upon dilution with about 30 to about 90 percent by weight of water based upon the total weight of the coolant. The alcohol is preferably ethylene glycol. The coolant compositions are especially effective in inhibiting the corrosion of aluminum internal combustion engine and radiator components.

International Classification:
C09K 1532
US Classification:
252 76
Abstract:
This invention relates to single-phase antifreeze or coolant concentrates comprising an alcohol, a corrosion inhibiting amount of a water-soluble organosiloxane-silicate copolymer corrosion inhibitor and an organic basic pH buffer capable of buffering pH in the range of about 9 to about 11 comprising a hydroxybenzoic acid or mixtures thereof. The concentrates are used as coolants either undiluted or upon dilution with about 25 percent to about 90 percent by weight of water based upon the total weight of the concentrate. The alcohol is preferably ethylene glycol. The coolant compositions are effective in providing protection against corrosion of all metals and alloys used in industrial heat exchangers are especially effective in inhibiting the corrosion of aluminum internal combustion engine and radiator components.

International Classification:
C09K 1532 C23F 1106 C23F 1110 C23F 1118
US Classification:
422 13
Abstract:
A single-phase antifreeze or coolant concentrate is disclosed comprising a major proportion of at least one alcohol, at least one water-soluble silicate, and an organic basic pH buffer and corrosion inhibitor comprising at least one hydroxybenzoic acid. The concentrates can be used without dilution but are preferably used, upon dilution with water. The concentrates are generally diluted for use in with about 25 to about 90 percent by weight of water based upon the total weight of the concentrate. The alcohol is preferably ethylene glycol. The alcohol-based antifreeze and coolant compositions of the invention are effective in the protection against corrosion of all metals and alloys used in industrial processes and are especially effective when used to inhibit the corrosion of aluminum internal combustion engine and radiator components.
