Cross-linking agent DE - Names and Identifiers
Cross-linking agent DE - Physico-chemical Properties
PH | 1.5~5.0 |
Physical and Chemical Properties | This product is a light brown viscous liquid. Available in any proportion diluted with water. Can be evenly dispersed in the printing paste, not alkali-resistant, not high temperature. |
Use | This product is mainly used as a crosslinking agent for pigment printing paste. Through the fixation process, it can form a network structure with the adhesive in the printing paste, achieving the purpose of firmness. It can improve the friction resistance and scratch fastness of the coating, and help improve the uniformity and color yield of the printing paste. It is a substitute for the crosslinking agent FH used in low-temperature pigment printing. It can be used in conjunction with non self intersecting high-temperature adhesives. It can also be used as a fixing agent for dyes such as sulfur and acid. |

Cross-linking agent DE - Introduction
Epoxy quaternary amine compounds are a class of quaternary amine compounds with epoxy structure. They have the following properties:
1. Reactivity: Due to the active epoxy group and quaternary amine group, these compounds have high reactivity. They can react with a variety of functional groups, such as carboxylic acids, phenols, aldehydes, etc., to form epoxy resins, amine-based curing agents, etc.
2. Solubility: Quaternary amine compounds with epoxy structural groups are often well dissolved in common organic solvents and can be evenly mixed with other substances.
3. High strength and good adhesion: After the curing reaction, the quaternary amine compounds with epoxy structural groups usually show high strength and good adhesion performance, which are suitable for coatings, adhesives, composite materials and other fields.
These compounds have a wide range of uses, including the following aspects:
1. coatings and adhesives: epoxy structure-based quaternary amine compounds can be used as active ingredients in coatings and adhesives for surface coating and bonding, providing excellent chemical resistance, abrasion resistance and adhesion.
2. Electronic materials: These compounds can be used to prepare electronic materials, such as electronic packaging materials, conductive adhesives, etc., with excellent electrical insulation and electrical conductivity.
3. Composites: Epoxy structure based quaternary amine compounds can be combined with fibers, fillers, etc. to form composite materials for the preparation of high-performance composite products, such as composite honeycomb panels, composite pipes, etc.
These compounds are generally prepared by synthesizing chemicals containing epoxy groups and quaternary amine groups. There are many specific synthetic methods, common methods include epoxy resin by amine base catalyst reaction.
Regarding safety information, the following points should be noted when using quaternary amine high-grade compounds with epoxy structural groups:
1. Avoid contact with skin and eyes: These compounds may be irritating to skin and eyes. Wear appropriate personal protective equipment such as gloves, safety glasses, etc.
2. Good ventilation: During use, maintain good ventilation to avoid inhaling harmful gases.
3. storage and disposal: storage should avoid mixing with other chemicals, avoid high temperature and fire. Waste disposal shall comply with local regulations and standards.
