  • FUNCTIONAL FRACTURE BRACE FOR FEMUR FRACTURES
    Publication number: 20180098873
    Abstract: A process for treating femoral fractures in children includes diagnosing a patient with a femoral shaft fracture and enclosing the affected limb in a splint. The process further includes scanning the unaffected limb with a three-dimensional scanner and obtaining measurements of the unaffected limb that may be used to form a brace for the affected limb. In addition, the process includes fabricating an orthosis to support the affected limb based on the scan and measurements taken of the unaffected limb, and applying the orthosis to the affected limb.

  • COLD CURING EPOXY RESIN PRIMER OR ADHESIVE
    Publication number: 20180094175
    Abstract: The invention relates to the use of an epoxy resin composition, containing at least one reaction product from the reaction of at least one amine of formula (I) with at least one carbonyl compound of formula (II) and hydrogen, as a cold curing primer or adhesive. Primers or adhesives of this type cure rapidly and trouble-free at ambient temperature, even at cold temperatures such as 10 or 5° C., suffer remarkably little yellowing and are free from toxic phenol compounds such as phenol, tert-butylphenol or nonylphenol. The primer has a particularly low viscosity and is particularly suitable for priming porous mineral substrates.

  • AMINE FOR RAPID-CURING EPOXY RESIN COMPOSITIONS
    Publication number: 20180079710
    Abstract: An amine of formula (I) which is particularly suitable for use as a curing agent for epoxy resins. The amine of formula (I) is devoid of non-incorporable toxic phenols, and is low-viscosity and pale in colour. It allows the production of easily-workable, low-emission or emission-free epoxy resin products which cure rapidly even at relatively low ambient temperatures thus obtaining a high degree of hardness and a nice surface with hardly any yellowing. This is particularly suited to use in floor or top coatings.

  • Amine for low-emission epoxy resin products
    Patent number: 9796661
    Abstract: The present invention relates to an amine of the formula (I) which is an adduct of 1,2-propylenediamine with an aryl monoglycidyl ether, to the use thereof as part of a hardener for epoxy resins, and to epoxy resin compositions obtained therewith.
