Process for curing polyepoxides and resulting products

Claim 2

A COMPOSITION COMPRISISNG THE CURED REACTION PRODUCT OF (1) A POLYEPOXIDE HAVING AN EPOXY EQUIVALENCY GREATER THAN 1.0, (2) A SALT OF AN N-AMINO ALKYL PIPERAZINE AND AN ACID SELECTED FROM THE GROUP CONSISTING OF INORGANIC ACIDS AND ORGANIC ACIDS CONTAINING FROM 1 TO 12 CARBON ATOMS, (3) AN INERT HIGH BOILING COMPATIBLE EXTENDER, AND (4) A DRY BASE WHICH IS MORE BASIC THAN THE N-AMINO ALKYL PIPERAZINE USED IS MAKING THE AFOREDESCRIBED SALT.

Claim 3

A PROCESS FOR CURING AT AOBUT 25%C. A POLYEPOXIDE PREPARED BY REACTING EPICHLOROHYDRIN WITH 2,2BIS(4-HYDROXYPHENYL)PROPANE AND HAVING AN AVERAGE MOLECULAR WEIGHT BETWEEN 350 AND 400, AN EPOXIDE EQUIVALENCY BETEEN 175 AND 210 AND AN OH EQUIVALENCY OF ABOUT 1250, WHICH COMPRISES MIXING THE SAID POLYEPOXIDE WITH (1) A PETROLEUM DERIVED SOLVENT EXTRACTED AROMATIC EXTRACT HAVING A SPECIFIC GRAVITY AT 60*F. OF ABOUT 0.99, A BISCOSITY AT 70*F. OF ABOUT 256 SSU, AN ANILINE POINT OF ABOUT -13*C., A POUR POINT OF ABOUT -35*F., A REFRACTIVE INDEX AT 50*C. OF ABOUT 1.55 AND A FLASH POINT OF ABOUT 330*F., (2) AN ACETATE SALT OF N-AMINO ALKYL PIPERAZINE, AND (3) DRY CAO, AND ALLOWING THE MIXTURE TO SET HARD AT ABOUT 25*C. TEMPERATURE.

Claim 4

A PROCESS FOR CURING AT AOBUT 25%C. A POLYEPOXIDE PREPARED BY REACTING EPICHLOROHYDRIN WITH 2,2BIS(4-HYDROXYPHENYL)PROPANE AND HAVING AN AVERAGE MOLECULAR WEIGHT BETWEEN 350 AND 400, AN EPOXIDE EQUIVALENCY BETEEN 175 AND 210 AND AN OH EQUIVALENCY OF ABOUT 1250, WHICH COMPRISES MIXING THE SAID POLYEPOXIDE WITH (1) A PETROLEUM DERIVED SOLVENT EXTRACTED AROMATIC EXTRACT HAVING A SPECIFIC GRAVITY AT 60*F. OF ABOUT 0.99, A BISCOSITY AT 70*F. OF ABOUT 256 SSU, AN ANILINE POINT OF ABOUT -13*C., A POUR POINT OF ABOUT -35*F., A REFRACTIVE INDEX AT 50*C. OF ABOUT 1.55 AND A FLASH POINT OF ABOUT 330*F., (2) AN ACETATE SALT OF N-AMINO ALKYL PIPERAZINE, AND (3) DRY CAO, AND ALLOWING THE MIXTURE TO SET HARD AT ABOUT 25*C. TEMPERATURE.
