Performance requirements for coating mildew protection agents
The ideal anti-mildew agent should meet the following conditions in the practical application: it has a very high killing ability for the erosion of the coating and the coating of various molds, a small amount, a wide range of application, lasting effect; Harmless to humans and animals, low toxicity or non-toxic, no irritation to the skin and eyes; Does not affect the physical and chemical properties of coatings and coatings; High stability, good heat resistance, light resistance and chemical resistance, small sublimation, not easy to be extracted by water, oil or solvent; Good compatibility with resins and other auxiliaries, no harmful chemical reactions; No corrosion of metal or various materials, no electrical corrosion; Odorless, light color, no pollution; Easy to use, low price. It is difficult, sometimes even impossible, to develop mildew protection agents that fully meet the above requirements. All kinds of mildew prevention agents have their own characteristics, some aspects of excellent performance, others show deficiencies. The synergistic effect of two or more kinds of mildew prevention agents can be played by compound mildew prevention agents.
