Usage and dosage:

Aldehyde resin has been proved to be able to comprehensively and effectively improve coating system’s yellowing-resistance, adhesion, hardness, gloss, solid contents and fullness when being used as an advanced multifunctional additive. 3-8%

·The shallow color and good pigment wetting function enable aldehyde resin particularly suitable for producing all-purpose pigment preparations. 15-30%

·The low viscosity of its solution enables high-pigment-content pastes to be produced.

·The good heat-resistance character enables aldehyde resin to find its application in baking finish house to endow desired properties for coating film’s strength and hardness.

the application in advanced wood paint has proved aldehyde resin will significantly promote the natural grain and color of wood as well as strengthen the coating film’s elasticity, adhesion, hardness and toughness.

Packing: In 25kg net per bags.
