Abstract: A curing agent for epoxy resins, including 1-amino-3-aminomethyl-3,5,5-trimethylcyclohexane and N-benzyl-1,2-ethandiamine in an amount for the ratio of the number of its amine hydrogens to be in the range of 90/10 to 20/80. The curing agent permits suitable epoxy resin compositions that have excellent workability and that cure particularly rapidly in cold and damp conditions, without blushing-induced surface defects, thus achieving coatings of in particular high hardness, high glass transition temperature and surprisingly little tendency to yellowing.

Abstract: An amino-functional addition product from the reaction of at least one diamine of the formula (I) with at least one aromatic diepoxide in a stoichiometric ratio in the range of 1.3 to 1.7 mole diamine per 1 mole-equivalent of epoxy groups. The addition product is liquid at room temperature without a diluent and has surprisingly low viscosity. The composition allows the manufacture of low-emission epoxy-resin coatings that have good workability, cure particularly rapidly and with high surface quality in cold and damp conditions, and allow for a wide range of combinations with other amines and diluents.

Abstract: An amine-functional adduct from the reaction of an amine mixture containing at least one diamine of formula (I) and at least one diamine of formula (II) in a weight ratio ranging from 65/35 to 95/5 with at least one diepoxide in a stoichiometric ratio of at least 1. 2 moles of diamine of the formula (I) to 1 mole equivalent of epoxide groups. The adduct is liquid at room temperature without diluent even in the presence of a small excess of diamine and is surprisingly low in viscosity. In addition, it is particularly cost-effective, as it is available from an amine mixture that is technically easy to produce. The adduct enables low-emission or emission-free epoxy resin coatings with surprisingly good workability at surprisingly fast curing, which have a high hardness and low tendency to yellowing, and which hardly tend to blushing-related defects even in cold and humid conditions.

Abstract: A coating system including at least one reactive resin system RH, at least one thixotropic assistant TH selected from the group consisting of urea preparations HZ and fibers FS and at least one inorganic aggregate AZ having a particle size in the range from 0.2 to 3.0 mm.

The coating system is notable for high surface roughness and for reliable and long-term bonding of the aggregates to the coating with no need for sealing. There is also no need for the coating to be subsequently strewn with aggregates such as sand, for example.
