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

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

 

Solubility

Aldehyde Resin A 81 is soluble in almost common paint 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,especially when the temperature is below 15°C, an appropriate amount of aromatic solvent can be added to stabilize it.

 

Compatibility

 Aldehyde Resin A 81 is compatible with nitrocellulose, CAB resins, chlorinated rubber, VC copolymers, acrylic resins, urea formaldehyde resins, melamine-formaldehyde resins, alkyd resins, epoxy resins, and hydrocarbon resins; limited compatibility with ethyl cellulose.It is compatible with many coating raw materials including:

Alkyd resin

Phenolic resin

Vinyl chloride copolymers

Phthalate plasticizer

Cellulose nitrate

Urea-formaldehyde resin

Acrylic resin

Melamine-formaldehyde resin

Cellulose acetate-butyrate

Epoxy resin

Polyurethane resin 

Polyamide resin

Petroleum resin

Rosin

Chlorinated rubber 

 

 

Features and advantages

Colorless or yellowish, high purity;

Good elasticity, adhesion, and hardness;

Excellent toughness and Anti yellowing performance;

Good pigment wetting,very low solution viscosity, is a kind of excellent grinding resin in universal pigment;

 Thermal stability.

 

Application

Aldehyde Resin A 81 mainly used in ordinary coatings and ink formulations, it has a wide range of applications in the following fields:

Solvent-based coatings and solvent-free coatings: It used to improve the yellowing resistance, weather resistance, gloss and adhesion of coatings.

Universal color paste: As a carrier resin for pigment color paste, it improves the compatibility and storage stability of pigment color paste.

Ink system: Used to improve the gloss, adhesion, flexibility and pigment wettability of ink.

Adhesive: Used to improve the leveling of adhesives and adhesion to substrates.

Powder coatings: Used to improve the leveling of powder coatings and enhance adhesion to substrates.

Plastic:Enhance coating adhesion, improve wetting and leveling properties.
