Aldehyde resin is a kind of aldehyde condensation resin, which is colorless or yellowish. It is soluble in almost painting solvents but not in water and compatible with practically all coating raw materials, it is excellently yellowing-resistant. It is usually as grinding resin in universal pigment and applied in coating formulation, It can effectively improve adhesion, hardness, gloss, solid content of painting and fullness of coatings. It is a kind of excellent multifunctional additive to coating.

[1] The resin is 50% (mass fraction) solution in butyl acetate and ethanol, they account for 85% and 15% respectively.

[2][3] 50% resin solution of ethanol, solution temperature remains 25°C when viscosity is tested.

 

 

GNC Aldehyde resin is soluble in almost common painting solvents such as aromatic hydrocarbons, alcohols, ketones, esters and so on but insoluble in water. Its solubility in nonpolar solvents such as mineral oil, aliphatic hydrocarbon, alicyclic hydrocarbon is limited.

 

GNC Aldehyde Resin is compatible with many coatings raw materials including:

• Alkyd resin

• Cellulose nitrate

• Cellulose acetate-butyrate

• Petroleum resin

•Phenolic resin

• Urea-formaldehyde resin

• Epoxy resin

• Rosin

• Vinyl chloride copolymers

• Acrylic resin

• Polyurethane resin

• Chlorinated rubber

• Phthalate plasticizer

• Melamine-formaldehyde resin

• Polyamide resin

 

·GNC Aldehyde resin can be used in many types formulation of coating/printing

·It can improve gloss, hardness, adhesion, and yellowing resistance of coating/printing

·It shows excellent wetting to filling and pigment, and is a kind of excellent grinding resin in universal pigment and can improve solid content when applied in coating.

·

Aldehyde resin is usually used in formulation if common coating/printing.

·GNC A-81benzene free is usually used in formulation of environmental-friendly coating/printing because there are no organics such as benzene, toluene, xylene and ketones.

 

GNC Aldehyde resin must be stored in dry and cool place, the period of validity is one year, it also can be used after one year if examined again and conformance to requirements.
