Flexible rubber joint flange corrosion protection coating construction of the basic requirements.
1 . Good adhesion and physical and mechanical properties: strong adhesion to the steel substrate or other coated materials, is the prerequisite for heavy anti-corrosion coating, especially the wet film adhesion, and has a low shrinkage rate, appropriate hardness, toughness, wear resistance, temperature resistance, etc.
2 . Good corrosion resistance: including resistance to chemical atmosphere, water, acid, alkali, salt, other solvents and other corrosion.
3 . Good resistance to media permeability: the excellent shielding effect of heavy anti-corrosion coatings requires that the coating has the lowest possible permeability to water and oxygen and other corrosion factors after film formation.
4 . Good construction performance: the coating reaches the appropriate thickness.
