    摘要: The invention relates to storage-stable, quick-curing epoxide resin moulding materials containing:A. pre-adducts containing aromatic constituents and free epoxide groups and formed from epoxide resins and polyamines,B. pre-adducts containing free amino groups and formed from polyamines containing cycloaliphatic or heterocyclic groups with polyglycidyl compounds, as curing agents, andC. mineral or organic pulverulent or fibrous fillers, with the epoxide resin pre-adducts and the curing agents softening between 45.degree. and 120.degree.C, and melting 5.degree. to 30.degree.C above the softening point, and the resin pre-adducts and the curing agents being present in the moulding materials predominantly in the form of particles separated from each other.The moulded articles are distinguished by very good stability to solar and UV rays, and retain their original colour to a very considerable extent even after prolonged irradiation.

    摘要: The invention relates to storage-stable, quick-curing epoxide resin moulding materials containing:A. epoxide resins,B. pre-adducts containing free amino groups and formed from polyamines containing aromatic groups and low-molecular epoxide resins, as curing agents, andC. mineral or organic pulverulent or fibrous fillers, with the epoxide resins and the curing agents softening between 45.degree. and 120.degree. C, and having a melting point higher by 5.degree. to 30.degree. C than the softening point, and being present in the said moulding materials predominantly in the form of particles separated from each other. The moulded articles have good mechanical and dielectrical properties.

    摘要: Epoxide resin foams are manufactured by curing a mixture which contains an epoxide resin, a blowing agent, a surface-active agent and the tetraglycidyl ester of cyclohexanone- or methylcyclohexanone-2,2,6,6-tetrapropionic acid, with a Lewis acid or an addition compound or complex compound of a Lewis acid. The foams obtained show a homogeneous pore structure and no tendency to crack formation, and are heat-stable and largely light-fast. They can be employed in sandwich constructions, as insulating materials against heat and cold, sound and mechanical impact, and in the electrical industry.
