Abstract
Epoxy resin composition curing agents, which include a primary amino alcohol, are disclosed. Specifically, the invention relates to curing agents which include a primary amino alcohol physically blended therewith. Alternatively, the invention relates to curing agents which include a primary amino alcohol reacted into a resinous phenolic compound. Resin systems utilizing the curing agents of the invention exhibit enhanced hot wet adhesion to metal substrates and are particularly useful in the manufacture of powder coatings for pipe.
Claims20
A curing composition for an epoxy resin composition comprising a primary amino alcohol physically blended, without the formation of a reaction product, with a curing agent wherein the primary amino alcohol is represented by the formula:
- wherein each of R1 and R2 is independently selected from the group consisting of R′O—, R′OO— and HO—CH2— where each R′ is hydrogen or a hydrocarbyl group containing 1 to 20 carbon.
A method for curing an epoxy resin composition comprising contacting the epoxy resin composition wit a curing agent comprising a primary amino alcohol reacted into a resinous phenolic compound wherein the primary amino alcohol is represented by the formula:
- wherein each of R1 and R2 is independently selected from the group consisting of R′O—, R′OO— and HO—CH2— where each R′ is hydrogen or a hydrocarbyl group containing 1 to 20 carbon atoms.
A curing composition for an epoxy resin composition comprising a primary amino alcohol physically blended, without the formation of a reaction product, with a curing agent, wherein the primary amino alcohol is represented by the formula:
- wherein each of R1 and R2 is independently selected from the group consisting of R′S—, R′2N—, R′2P—, and R′3Si— where each R′ is hydrogen or a hydrocarbyl group containing 1 to 20 carbon atoms.
A curing composition for an epoxy resin composition, wherein the curing composition comprises a primary amino alcohol physically blended, without the formation of a reaction product, with a curing agent, wherein the primary amino alcohol is selected from the group consisting of 2-amino-1-butanol, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-methyl-1-propanol, 2-amino-2-ethyl-1,3-propanediol, 2-amino-3-methyl-1-butanol, 2-amino-1-hexanol, tris(hydroxymethyl)aminomethane and combinations thereof.
An epoxy resin composition comprising an epoxy resin and a curing composition, wherein the curing composition comprises a primary amino alcohol physically blended, without the formation of a reaction product, with a curing agent, wherein the primary amino alcohol is selected from the group consisting of 2-amino-1-butanol, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-methyl-1-propanol, 2-amino-2-ethyl-1,3-propanediol, 2-amino-3-methyl-1-butanol, 2-amino-1-hexanol, tris(hydroxymethyl)aminomethane and combinations thereof.
