AKD resin - Names and Identifiers
AKD resin - Introduction
AKD resin(Alkyl Ketene Dimer Resin) is a synthetic resin with a series of excellent properties. The following is an introduction to the nature, use, formulation and safety information of AKD resin:
Nature:
1. AKD resin is a colorless or pale yellow solid.
2. It has good water resistance and alkali resistance.
3. AKD resin has good solubility and can be dissolved in organic solvents.
4. It has excellent ink affinity and can be used as an additive for coatings and inks.
Use:
1. AKD resin is mainly used in paper and coating industry.
2. In the paper industry, it is used as the inner surface sizing agent of paper, which can improve the water resistance and printing performance of paper.
3. In the coatings industry, AKD resin can be used as a thickener and lubricant to improve the performance of coatings.
Preparation Method:
The preparation of AKD resin is usually achieved by catalyzing the reaction of α,β-unsaturated ketones with fatty acids by base catalysts. The process involves mixing a fatty acid with a ketone and performing an acylation reaction in the presence of a base catalyst. The final product is a far-infrared hybrid resin with fatty acid alkyl side chains.
Safety Information:
1. AKD resin is relatively safe under normal use conditions, but protective measures still need to be paid attention.
2. use should wear protective gloves and glasses, avoid contact with skin and eyes.
3. Avoid inhaling AKD resin dust or steam, and should be used in a well-ventilated area.
4. AKD resin should be stored in a dry, cool place, away from fire and oxidant.
