Eco-friendly: water as diluent, very low VOC usually <=50 g/L, far below solvent paint; free of benzene, formaldehyde and heavy metals, little pollution to air or indoors. Safe: non-flammable, safer storage and application, lower fire risk. Excellent performance: new-generation waterborne resins give adhesion comparable to oil-based paint on many substrates; some water-based polyurethanes offer superior crack and UV resistance. Easy application: tools clean with water, lowering cleaning cost; suits spray, brush, dip and other methods.
