Classification of crosslinking agent for epoxy resin coating

The classification of the crosslinking agent of epoxy coatings can be classified into two types: alkaline and acidic.

The alkaline cross-linking agent in the classification of epoxy resins: fatty diamine, polyamine, aromatic polyamine, dicyandiamine, mimidazolam and modified amines.

Acid crosslinking agent in the classification of the crosslinking agent of epoxy resin: organic anhydride, boron trifluoride and complex.

The classification of the crosslinking agent of epoxy resin can be divided into additive forming and catalytic type according to the crosslinking mechanism.

Molding cross-linking agent: fatty amine, aromatic, fatty ring, modified amine, anhydride, low molecular polyamide and latent amine.

Catalytic crosslinking agent: tertiary amines and mimidazolis.

At present, epoxies are generally labeled with epoxy-value, converting it to epoxy-equivalent, epoxy-equivalent = 100 / epoxy, and epoxy equivalent is the quality of a resin containing 1 mole of epoxy. The amines cross linking agent is now labeled with amine value, converting it to amine hydrogen equivalent, amine hydrogen equivalent is 56000 / amine value, and amine hydrogen equivalent is the quality of resin containing 1 mole of active hydrogen. The ratio of epoxy resin and crosslinking agent is the ratio of epoxide equivalent to amines equivalent. Note that this is pure resin, and if you have a solvent, you divide it by the amount of solid content, and then the ratio, if it's a reactive diluent, it's another meter. This model is also available for other types of crosslinking agents.

Notice of crosslinking agent

Chemical name: peroxide methyl ethyl ketone, PH value is neutral and weak acidic organic solvent. The peroxide will react with the rubber.

Packing Group: III

Hazard Class: 6.1

Evacuate the area of the spill area quickly to the safe area, and quarantine, strictly restrict access; Cut off the ignition source; Do not contact the leakage directly, as far as possible to cut off the leakage source, to prevent access to the drain, drain and other space.

1. Small leakage:

To absorb or absorb with sand or other noncombustible materials. It can also be washed with a large amount of water and diluted with the lotion and put into the waste water system.

2. Large amounts of leakage:

3. Build dikes or pit shelters; Cover with foam and reduce steam hazard. Use explosion-proof pump to transfer into tank or special collector. Recycle or transport to waste disposal site.

Protection measures

1. Smoking is strictly prohibited in the workplace

2. Wear rubber gloves

3. Use area to place clean water

4. The safe storage distance of the crosslinking agent and accelerant is more than 20 meters

5. The production of residual crosslinking agent is timely recycled into the special sealed bucket

6. When the crosslinking agent is separated, the basin or bucket will be put into the water, which can be diluted when leaking.

First aid measures

1. Skin contact: remove contaminated clothing and rinse thoroughly with soapy water and water.

2. Eye contact: lift eyelid and wash or seek medical treatment with flowing water or saline.

3. Inhalation: quickly disengage from the scene to fresh air. Keep the airway open. If it is difficult to breathe immediately oxygen. If breathing is stopped immediately, artificial respiration or medical treatment.

4. Food intake: drink plenty of warm water, urge vomiting, and wash the stomach with water or 1% sodium sulphate solution. Go to a doctor.
