Water Based Polyurethane PU Wood Paint
Water- based green wood paint
Used in all kinds of wood surface decoration, especially for places that has strict require on little odor and high standard on environmental protection.
Brush or spray, spray is recommended for finishing coat.
Base material (240-320# abrasive paper, completely polished and cleaned among layers) → seal primer (once, spray or brush evenly) → priming coat (twice, 240-320# abrasive paper, completely polished and cleaned among layers) → finishing coat (twice)
Paint Consumption in Theory
10-13 m/time (brush with mixture, 30 micron dry film)
Formulation (by weight)
1. Double components: main paint : curing agent : water = 6 : 1 : 0.1-0.2
