Polyketone resin for printing ink paint

Polyketone resin for printing ink paint exhibits excellent adhesion, mainly due to its unique chemical structure and performance characteristics. The following is a detailed analysis of the adhesion of polyketone resin for printing ink paints:

1. Chemical structural characteristics of polyketide resin

Polyketone resin, also known as aldehyde ketone resin or ketone aldehyde resin, is a polymer formed by the condensation reaction of ketones and aldehydes. Its molecular structure contains carbonyl and hydroxyl groups, which endow polyketide resin with good polarity and solubility, making it compatible with various ink and coating components, thereby enhancing adhesion.

2. Adhesion performance of polyketide resin in ink coatings

Enhancing adhesion to substrates: Polyketone resin for printing ink paints can significantly enhance adhesion to substrates (such as plastics, metals, paper, etc.) through hydrogen bonding and intermolecular forces. Experimental data shows that the addition of polyketide resin can improve the adhesion strength of ink coatings on substrates by 5% -10%.
Improving the wetting and dispersibility of pigments: Polyketone resin has a good wetting and dispersing effect on pigments, which helps to achieve uniform distribution of pigments in ink coatings, thereby further improving adhesion and printing effects.

Improving the flowability of ink coatings: The low viscosity characteristics of polyketide resin help improve the flowability of ink coatings, making them easier to apply to substrates and form uniform and firm coatings.

3. Practical application cases of strong adhesion of polyketide resin

In the field of ink, polyketide resins (such as KR-120, CT-120, etc.) are widely used in high-end printing and special application scenarios such as plastic surface printing ink, aluminum foil ink, and hot stamping ink. Experimental data shows that adding 2% -3% of polyketide resin to ink coatings can increase the glossiness (60 °) of plastic surface printing ink from 85% to 95%, while significantly improving adhesion.

In the field of coatings, polyketone resin for printing ink paints also performs well. For example, mixing KR-120 aldehyde ketone resin with nitrocellulose, polyamide resin, and other materials can significantly improve the adhesion, glossiness, and hardness of coatings used in wood and automotive paints.

4. Summary

In summary, polyketone resin for printing ink paintexhibits excellent adhesion, mainly due to its unique chemical structure and performance characteristics. In practical applications, polyketide resin can significantly enhance the adhesion between ink coatings and substrates, improve pigment wetting and dispersibility, enhance flowability, and thus improve printing and coating effects. Therefore, polyketide resin is one of the indispensable and important raw materials in the field of ink coatings.
