Mixed polycycloaliphatic amines (MPCA) and alkylates thereof (MPCA alkylates), methods for making mixed polycycloaliphatic MPCA amines and MPCA alkylates thereof, as well as polymeric compositions, such as spray-applied polyurea coating compositions, comprising said mixed amines MPCA and MPCA alkylates thereof are described herein. In one embodiment, the polymeric composition comprises an isocyanate component, and a resin component comprising an organic compound having the following Formula I: where R, Rand Rare each independently selected from a hydrogen atom, an alkyl group comprising from 1 to 20 carbon atoms, an aryl group comprising from 3 to 12 carbon atoms, an aralkyl group comprising from 3 to 12 carbon atoms and combinations thereof, provided that there is at least one alkyl group within Formula I, and X is a methylene bridged polycycloaliphatic amine (MPCA).

Mixed polycycloaliphatic amines (MPCA) and MPCA alkylates

The present invention provides curing agent compositions comprising alkylated polyalkylene polyamine compounds. Amine-epoxy compositions and articles produced from these amine-epoxy compositions are also disclosed.

Alkylated polyalkylene polyamines and uses thereof

The present invention discloses both amine compositions and amine-epoxy compositions containing N,N'-dimethyl-meta-xylylenediamine. A novel process for producing amines such as N,N&#x2032;-dimethyl-meta-xylylenediamine, and structurally similar amines, is also disclosed.

Curing agent of N,N'-dimethyl-meta-xylylenediamine and multifunctional amin(s)

The present invention provides epoxy curing agent compositions comprising alkylated aminopropylated alkylenediamine compounds. Amine-epoxy compositions and articles produced from these amine-epoxy compositions are also disclosed.

Alkylated aminopropylated ethylenediamines and uses thereof

This invention pertains to alkyl substituted bi(cyclohexylamine) and derivatives having a high trans, trans-isomer distribution. This isomer distribution represents a thermodynamic mixture of the isomers and provides for extended pot life and extended thermal properties in epoxy resins which are not seen with the kinetic isomer mixture. The bridged cyclohexylamine and derivatives are represented by the formula: ##STR1## wherein; R.sup.1 is hydrogen or C.sub.1-4 alkyl;

Thermodynamic mixture of alkyl substituted bi(cyclohexylamine) isomers

This invention pertains to epoxy resins having increased chemical resistance to solvents, and good cured mechanical properties which are prepared by curing the epoxy resins with a curing agent comprising a mixture of methylene bridged poly(cyclohexyl-aromatic)amines. The methylene bridged poly(cyclohexyl-aromatic)amine curing agents are the residue obtained from the distillation of a mixture of poly(cyclohexylaromatic)amines formed by the hydrogenation of crude methylenedianiline or crude di(4-amino-3-methylcyclohexyl)methane.

Epoxy resins cured with mixed methylene bridged

This invention pertains to alkyl substituted bi(cyclohexylamine) and derivatives having a high trans,trans-isomer distribution. This isomer distribution represents a thermodynamic mixture of the isomers and provides for extended pot life and extended thermal properties in epoxy resins which are not seen with the kinetic isomer mixture. The bridged cyclohexylamine and derivatives are represented by the formula: ##STR1## wherein; R.sup.1 is hydrogen or C.sub.1-4 alkyl;

Alkyl substituted bi(cyclohexylamines)

This invention relates to ditertiary-butyl substituted bridged di(cyclohexylamines) where the tert-butyl substituent is alpha to the amine group and to polyepoxide formulations incorporating the di(cyclohexylamine). The formula of the diamine is: ##STR1## wherein R is tert-butyl. The di(tertiary butyl)methylene bridged cyclohexylamines have delayed reactivity when incorporated in epoxy resins and they also enhance physical properties in high resilience polyurethane foams.

Sterically hindered ditertiary butyl bridged di(cyclohexylamines)

This invention relates to polyepoxide resins cured with an amine composition containing 1-methyl-2,6-cyclohexanediamine. The resulting polyepoxide resins generally are more easily processable and have improved thermal stability, greater elongation and enhanced fracture toughness.

Epoxy resin systems containing methyl-2,6,-cyclohexanediamine

This invention relates to bridged cyclohexylamines represented by the formula: ##STR1## A is C.sub.0, --CH.sub.2 --, ##STR2## R.sub.1 is C.sub.1-3 alkyl R.sub.2 is C.sub.1-6 alkyl

Bridge bis(cyclohexylamine) curing agents for epoxy resins

Polymeric compositions are prepared from ethylenically unsaturated monomeric compositions and polyarylcyanate ester compositions which have at least two arylcyanate ester moieties bridged by a polycyclic aliphatic moiety; and wherein the polyarylcyanate ester composition is substantially soluble in the ethylenically unsaturated monomeric composition.

Curable composition from ethylenically unsaturated monomers and

Laminates are prepared for reinforced expoxy resin compositions comprising (A) a reinforcing material such as fiberglass, (B) one or more epoxy resins such as a hydrocarbon-phenol eposy resin and (C) one or more epoxy resin curing agents such as a hydrocarbon-phenol resin or phenol-formaldehyde novolac resin. These laminates are particularly suitable for use in electrical applications such as the manufacture of printed circuit boards.

Laminates from epoxidized phenol-hydrocarbon adducts

Curable compositions are prepared from reinforced epoxy resin compositions comprising (A) a filler material such as silica flour, (B) one or more epoxy resins at least one of which is a hydrocarbon novolac epoxy resin such as a phenol-dicyclopentadiene epoxy novolac resin and (C) one or more epoxy resin curing agents such as phenol-formaldehyde novolac resin. These compositions are particularly suitable for use in electrical applications such as the encapsulation and subsequent protection of electrical and micro-electronic devices and circuitry and in adhesive formulations.

Durable epoxy resin

The combination of n-butanol, n-hexanol and butoxyethanol, is a superior formulation solvent for aqueous dispersions of amine-neutralized, phosphorylated DGEBA-type epoxy resins which are to be applied to container interiors by spraying. Good film rheology and control of viscosity--by adjusting the solvent to organic solids ratio--is attained at total solids content as low as 20 wt. % and at VOC's as low as 3.5 lbs. per gallon.
