20130225723 | CONDENSATION PRODUCTS OF AMINO-FUNCTIONAL POLYMERS - A condensation product of at least one (hydroxymethyl)phenol and at least one polyoxyalkylene diamine and a process for the preparation thereof and the use thereof in the curing of epoxy resin systems are described. | 08-29-2013 |
20140107313 | LOW-EMISSION HARDENER FOR EPOXY RESINS - The present invention concerns a low-odor, low-viscosity hardener for epoxy resins comprising the amine of formula (I), | 04-17-2014 |
20140128506 | HARDENER FOR EPOXY RESINS - The present invention concerns low-odor, low-viscosity hardeners for epoxy resins, including an amine with at least one amino group of formula (I) and an amine with at least one amino group of formula (II), wherein the amino groups of formulas (I) and (II) are present in a particular ratio. | 05-08-2014 |
20140288247 | HARDENERS FOR EPOXY RESIN COATINGS - The invention relates to hardeners for epoxy resin containing secondary amino groups having dialkyl amino phenyl groups. The hardeners have a surprisingly low viscosity and harden surprisingly fast together with the epoxy resins, even in moist, cold conditions, and without blushing to form films with high hardness and stability. They are suitable, in particular, for low-emission coatings. | 09-25-2014 |
20140309334 | CURING AGENT FOR EPOXY RESIN COATINGS - The present invention relates to curing agents for epoxy resins including an alkylated polyethyleneimine. These curing agents have high functionality and a high content of secondary amino groups. Together with epoxy resins, they cure surprisingly quickly and without blushing effects even under humid and cold conditions to form films having very high cross-linking density. They are suited for coatings with high resistance requirements. | 10-16-2014 |
20140316080 | HARDENERS FOR EPOXY RESINS, WHICH COMPRISE PYRIDINYL GROUPS - The present invention relates to hardeners for epoxy resins, which contain secondary amino groups having pyridinyl groups. They harden surprisingly quickly together with epoxy resins even under cold and humid conditions and without producing blushing to give films with a high degree of hardness, the highest degrees of hardness being obtained with a surprisingly low amount of hardener required. They are especially suitable for low-emission coatings with high resistance requirements. | 10-23-2014 |
20150337076 | CURING AGENTS FOR LOW-EMISSION EXPOXY RESIN PRODUCTS - The present invention relates to curing agents for epoxy resins, containing at least one adduct of a primary diamine and an aromatic monoepoxide, at least one primary diamine and at least one secondary diamine which is free of primary amino groups and free of hydroxyl groups. The curing agent is of low viscosity and cures, together with epoxy resins, rapidly and without blushing, even under damp, cold conditions, to form films of high hardness and low brittleness. It is particularly well suited for low-emission coatings that cure at room temperature. | 11-26-2015 |
20150344406 | AMINE FOR LOW-EMISSION EPOXY RESIN PRODUCTS - An amine which can be used in epoxy resin compositions that cure at room temperature. The amine dilutes the composition highly effectively, allows rapid, trouble-free curing, even in cold and damp conditions, and reduces brittleness. The amine is particularly suitable as a constituent of a curing agent for low-emission epoxy resin compositions that cure at room temperature, in particular for floor coverings. | 12-03-2015 |
20150344615 | CURING AGENTS FOR LOW-EMISSION EPOXY RESIN PRODUCTS - The present invention relates to curing agents for epoxy resins, containing at least one adduct of trimethylhexamethylenediamine and cresyl glycidyl ether. The curing agent has a low viscosity and cures quickly together with epoxy resins even in moist, cold conditions and without blushing to form films with a high hardness and surface quality, which scarcely undergo yellowing upon exposure to light. It is particularly suited for low-emission room temperature-curing coatings. | 12-03-2015 |
