Technical Information of INT Cyclohexanone-formaldehyde Resin

Cyclohexanone-formaldehyde resin is the condensation polymer of cyclohexanone and formaldehyde, which includes carbonyl and hydroxyl group, it can also be called ketone aldehyde resin. It shows excellent compatibility with almost coating/printing raw materials. It is soluble in almost organic solvents and exhibits good wetting and dispersion to the filling and pigment. It can also improve yellowing-resistant, adhesion, gloss and hardness of coating. It is a kind of excellent multifunctional additive of coating. It is usually as grinding resin in universal pigment and coating/painting. There are INT 105, INT 120, INT 120L and INT 130 according to different property and application.

ASTM D1200

[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 detected.

Solubility

Cyclohexanone-formaldehyde resin 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, which should be paid attention. 

 

Application

Cyclohexanone-formaldehyde resin is characteristic of excellent compatibility, solubility and transparency, which enable it to improve gloss, adhesion, hardness, fullness and dryness when applied in formulation of coatings/printing. It is a kind of excellent grinding resin in universal pigment and can improve solid content when applied in coating.

·INT 105 resin is used for formulation of coating/printing which requires high adehesion.

·INT 120 resin is used for formulation of common coating/printing.

·INT 120L resin is almost odorless, so it is used for formulation of coating/printing which requires inodorous.
