An etheramine mixture comprising one or more polyether diamines, methods for its production, and its use as a curing agent for epoxy resins. The etheramine mixture may also be used in the preparation of polyamides and polyurea compounds.

Etheramine mixture containing polyether diamines and method of making and using the same

An admixture composition for use in cementitious compositions for improving the properties of the cementitious composition wherein the admixture composition comprises at least a polycarboxylate type comb-polymer dispersant and a hydroxyl amine compound selected from EDIPA (N,N-bis (2 hydroxypropyl)-N-(hydroxyethyl) amine) and optionally one or more polyhydroxyalkyl ethyleneamine compounds.

Admixture composition to improve strength of cement cured products

Implementations described herein generally relate to etheramine mixtures formed from a mixture of two or more multifunctional alcohol initiators, processes for the etheramine mixtures production, and its use as a curing agent or as a raw material in the synthesis of polymers. In one implementation, the process comprises mixing a polyol initiator having a melting point greater than a processing temperature and a polyol initiator having a melting point less than the processing temperature to form a polyol initiator mixture having a melting point less than the processing temperature, charging the polyol initiator mixture to an alkoxylation reaction zone, contacting the polyol initiator mixture with an alkylene oxide in the alkoxylation reaction zone to provide a mixture of alkoxylated precursor polyols and charging the mixture of alkoxylated precursor polyols to a reductive amination zone and reductively aminating the mixture of alkoxylated precursor polyols to form the etheramine mixture.

Etheramines prepared from a mixture of two or more multifunctional alcohol initiators, and their use as curatives or intermediates for polymer synthesis

The present disclosure provides a curable composition that includes an epoxy resin and a curing component comprising a blend of at least two amines. The curable composition may be combined with reinforced fibers and cured to form a composite article which can be used in various applications, such as in wind turbine blades.

Blend for curing epoxy resin composistions

The present disclosure provides a process for the co-preparation of a polyetheramine and an alkylene amine mixture by aminating a liquid polyol initiator mixture comprising an alkoxylated alcohol and a solid high melting polyol. The polyetheramine and alkylene amine mixture may be used in a variety of applications, such as a curing agent for epoxy resin formulations or as a raw material in the synthesis of polyurea.

Co-preparation of polyetheramines and alklyene amines

Provided herein are compositions useful as ink or coatings which contain novel dispersants that are capable of dispersing pigments which are traditionally difficult to disperse while maintaining acceptable levels of viscosity. Use of dispersants as taught herein enables the preparation of a wide variety of inks and coatings having high pigment loading and existing within a conventionally-useful viscosity range.

Etheramines and their use as curatives or intermediates for polymer synthesis

Embodiments described herein provide a dispersant for ink and pigmented coatings. The dispersant is a polyurethane having oxamide diol groups. The dispersant may be used to prepare a wide variety of inks and coatings having high pigment loading and existing within a conventionally-useful viscosity range.

Comb polyurethane dispersants

The present disclosure relates to pyrrolidine-based catalysts for use in a polyurethane formulation. The polyurethane formulation includes the pyrrolidine-based catalyst, a compound containing an isocyanate functional group, an active hydrogen-containing compound. The use of such catalysts produces high quality polyurethane foam while reducing environmental concerns that can arise during the production of polyurethane foam as well as in the foam that is produced.

Pyrrolidine-based catalysts for use in polyurethane materials

Implementations described herein relate to an etheramine mixture containing a cyclobutane based amine and its method of production by alkoxylating an initiator with an alkylene oxide to produce a precursor polyol and reductively aminating the precursor polyol to form the ehteramine mixture. The etheramine mixture may be used in a variety of applications including as a curing agent for an epoxy resin or as a reactant in the production of polyurea materials.
