Epoxy floor paint products have high viscosity, induction period, poor compatibility with epoxy resin, low curing thermal stability, good adhesion, strength and toughness, mainly used in high solid paint, sealant, cable connector, adhesive, ester, cyclic amine aliphatic ester, that is, cyclic amine low viscosity. Compared with polyamide, it has good chemical resistance, non-white paint, no induction period, but poor toughness, low curing activity, need heating ability after curing, and can be cured at room temperature only after adding accelerator or modification conditions.
Aromatic amines and m-phenylenediamine are used in corrosion-resistant coatings. Apart from phenylene dimethylamine which has some aliphatic structure, the curing agent is a normal temperature solid. Therefore, when mixed with resin, it is usually cured by heating. MILL.Y is used in the curing process, and the coating can also be used as the raw material of modified amine curing agent.
Generally speaking, a single polyamine has small molecular weight, volatility, toxicity and high cross-linking density. After reaction, it is cured with epoxy resin with high brittleness and impact resistance. Generally, it is not a single polyamine, especially aliphatic monoamine with small molecular weight, volatility, high toxicity and fast reaction.
Reducing the amount of unreacted polyamines can absorb moisture in the air and sweat the surface of the coating, which limits the application of monoamines as curing agents for epoxy resins. In order to overcome the shortcomings of brittle amine curing agents and silicone high-temperature-resistant paints, such as poor impact resistance, poor weatherability and high toxicity, it is necessary to further modify monoamines as curing agents. To achieve non-toxic or low toxicity.
Under the greenhouse curing condition, the epoxy zinc-rich primer with epoxy curing agent usually has high molecular weight, high boiling point, auxiliaries and viscosities due to excessive reaction, and the irritation of skin and mucous membrane is greatly reduced. Because of TH, the curing reaction of E-adduct is usually fast, and the mechanical properties of alkyd paint cured are changed from the original polyamination. The nature of learning is a bit different.
