    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： The invention relates to epoxy molding compositions consisting of diglycidyl ethers of bisphenols, anhydride hardeners and reinforcing fillers. At least half the total amount of filler consists of wollastonite. These molding compositions have greater resistance to cracking, which is particularly advantageous in encasing metal parts.

    摘要： The invention relates to heat curable epoxy resin compositions consisting of an epoxy resin containing, on average, more than one epoxide group per molecule, an aromatic onium salt as catalyst, a copper complex compound as co-catalyst, and a light stabilizer. These compositions are less sensitive to UV irradiation and have a good shelf life at room temperature as well as a good high temperature reactivity.
