An insulation product includes mineral fibers and a binder obtained by curing a binding compound, includes as components a) compounds including at least one epoxy function, including at least one epoxy precursor chosen from aliphatic compounds including at least two epoxy functions, b) a hardener chosen from compounds including at least two reactive functions chosen from hydroxyl and carboxylic acid functions, it being possible for the carboxylic acid function(s) to be in salt or anhydride form.

The invention provides highly functional epoxy resins that may be used themselves in coating formulations and applications but which may be further functionalized via ring-opening reactions of the epoxy groups yielding derivative resins with other useful functionalities. The highly functional epoxy resins are synthesized from the epoxidation of vegetable or seed oil esters of polyols having 4 or more hydroxyl groups/molecule. In one embodiment, the polyol is sucrose and the vegetable or seed oil is selected from corn oil, castor oil, soybean oil, safflower oil, sunflower oil, linseed oil, tall oil fatty acid, tung oil, vernonia oil, and mixtures thereof. Methods of making of the epoxy resin and each of its derivative resins are disclosed as are coating compositions and coated objects using each of the resins.

The utility model relates to the light industry and is intended for use as a prophylactic and hygienic means for human feet. A shoe insole with amber consists of a base and filler, wherein the base is made of an adhesive composition, in which the filler is located, and the filler is amber stones. The insole allows maintaining the prophylactic and hygienic effect during a long-term use thereof.

The invention relates to novel curable bio-based thermosetting compositions of a) at least one highly-functional bio-based epoxy resin; and b) at least one carboxylic acid crosslinker selected from the group consisting of a water-soluble multifunctional carboxylic acid, a dicarboxylic acid oligomer from a melt reaction between a diol and a dicarboxylic acid or its anhydride, and mixtures thereof and which are curable with water, an alcohol or a water and alcohol mixture. The bio-based thermosets of the invention may be free of VOCs and/or organic solvents. The bio-based thermosets of the invention can be used to form coatings, composites, adhesives, and films. Methods of making the bio-based thermosets of the invention are disclosed as are coating compositions and coated objects, such as coatings, composites, adhesives, and films, using the bio-based thermosets of the invention.

An aqueous dispersion comprising at least one fatty acid-modified epoxy amine adduct wherein the fatty acid has an iodine number of lower than 30 and at least one polymer obtained from the polymerization of one or more ethylenically unsaturated monomers and their use for forming coatings or binder agents, especially for decorative and protective coating applications on various substrates.

This disclosure relates to epoxy compositions and more particularly to two-part epoxy compositions that are useful for marking substrates, such as roadway and airport runway surfaces. The compositions and methods described herein can reduce build-up on applicator pump seals. Such build-up can lead to pump failure. In some cases, the compositions can reduce down-time due to pump failure. However, the compositions retain the necessary properties for substrate marking, such as curing within a short period of time.

An insulation product includes mineral fibers and a binder obtained by curing a binding compound, includes as components a) compounds including at least one epoxy function, including at least one epoxy precursor chosen from aliphatic compounds including at least two epoxy functions, b) a hardener chosen from compounds including at least two reactive functions chosen from hydroxyl and carboxylic acid functions, it being possible for the carboxylic acid function(s) to be in salt or anhydride form.

Epoxy curing agents are disclosed having an epoxy curing agent comprising at least one room temperature ionic liquid salt, the room temperature ionic liquid salt being a reaction product of (a) at least one polyalkylene polyamine compound represented by formula (I):

##STR00001##

wherein x, y, and z are integers of 2 and 3, m and n and integers of 1-3; and (b) an organic acid having pKa (the negative of the logarithm of the acid dissociation constant) less than 6. The liquid salt is a stable liquid at a temperature greater than 15 C. Curable epoxy-based compositions including the curing agent and articles formed by the curable epoxy-based compositions are also disclosed.

The present disclosure provides a fire retardant composition that includes a non-intumescent composition and an intumescent composition, fire retardant coatings including the same, and methods of preparation and use thereof.

Described herein are liquid crystalline elastomer compositions comprising aromatic epoxy units crosslinked with alkylene diacid units having alkylene segments containing at least one methylene unit, and/or aromatic epoxy units crosslinked with polyphenolic units, wherein the aromatic epoxy units and alkylene diacid units and/or polyphenolic units are in a molar ratio that results in the liquid crystalline elastomer composition exhibiting a glass transition temperature (T.sub.g) and a thermal stability of the liquid crystalline phase (T.sub.lc) that make them particularly suitable as shape memory materials and for use in methods of additive manufacturing. Methods for producing these compositions and their use in additive manufacturing processes are also described.
