Remark [1]: this kind of paint is made up of EH-829 emulsion and titanium dioxide, color paste and auxiliary agent. Different preparation schemes may have different properties of paint.
■Performance and Application
EH-829 Epoxy Modified Self-crosslinkable Acrylic Emulsion combined with titanium dioxide, color paste and additives can be used as environmentally friendly, non-toxic and durable waterborne paint. It belongs to constant temperature curing metal paint emulsion.
The paint mold has high hardness, strong adhesion, and has excellent gloss, water resistance, impact resistance, salt fog resistance, acid and alkali resistance and ultraviolet resistance, light retention and other characteristics. There are two properties of thermal crosslinking and self-crosslinkable, which are substitutes for oil paint and polyester paint.
