摘要： The present invention relates to a multi-component epoxy resin composition, comprising
- a first component comprising
- at least one epoxy resin that contains on average more than one epoxy group per molecule;
- optionally at least one reactive diluent having one epoxy group per molecule;
- optionally further additives; and
- a second component comprising
- at least one amine hardener for epoxy resins;
- optionally further additives; and
- a third component consisting of
- an aqueous solution of at least one metal salt, wherein said solution contains between 20 parts by weight and 80 parts by weight, preferably between 30 parts by weight and 70 parts by weight, in particular between 40 parts by weight and 60 parts by weight, of said metal salt, based on 100 parts per weight of water is said aqueous solution;
wherein the weight ratio of the second component to the third component is between 100 : 0.3 and 100 : 10, preferably between 100 : 1 and 100 : 5.
The combination of the water-based curing-accelerating third component with common two-component epoxy resin compositions leads to significant curing acceleration of two-component epoxy resin compositions without the requirement for heating and without adversely affecting the properties of the cured epoxy resin composition.-
