    摘要： The invention relates to the production of chemically resistant epoxide resin layers on solid surfaces. The liquid component (A) which contains an epoxide compound is preferably mixed, and applied, together with the component (B) containing the curing agent, in a spraying apparatus. The coating is then cured. The curing agent contained in (B) consists essentially of Zn(BF.sub.4).sub.2, quite specific ethers or thioethers, an acid ester of the phosphoric or pyrophosphoric acids or a certain phosphonic acid ester and water. The system is characterized by a short is preferably mixed, and applied, together with the component (b) containing the curing agent, in a spraying apparatus. The coating is then cured. The curing agent contained in (B) consists essentially of ZN(BF.sub.4).sub.2, quite specific ethers or thioethers, an acid ester of th phosphoric or pyrophosphoric acids or a certain phosphonic acid ester and water. The system is characterized by a short curing time and produces coatings which adhere strongly and are resistant to chemicals. If the component (A) contains an epoxide compound which consists to the extent of 50 to 100% by weight of a cycloaliphatic epoxide compound, a coating is finally obtained which is resistant to weathering.
