10-Micron-Superfine -Dicyandiamide

Micron-Superfine -Dicyandiamide introduction 

The most core function of superfine dicyandiamide is as a latent curing agent, used in fields that require high-performance c. Superfine dicyandiamide is a superfine, high-purity, modified latent curing agent, presented as a white ultra-micron powder. Under dry, it exhibits stable chemical properties and is non-flammable. Its different models (such as SH-900, SH-500, SH-300 may show different technical properties in specific applications. Superfine dicyandiamide is widely used in the adhesive industry, composite field, powder coating industry, etc., as key component for the production of epoxy solid adhesives, one-component epoxy resin adhesives, carbon fiber prepregs, high-grade powder coatings, etc In the process of use, the addition amount of superfine dicyandiamide curing agent is usually 8-12% of the total resin weight, and the amount of promoter SH-A100 is 2-4% of the total resin weight.

The following points should be noted when using cyanamide superfine powder: 

Safety protection measures: Operators should take protective measures, such as wearing chemical safety goggles, protective clothing, and gloves. Smoking, eating, and drinking should be prohibited at the work site, and a shower and of clothes should be taken after work to maintain good hygiene habits. 

Avoid contact with eyes and skin: Cyanamide superfine powder may be irritating to eyes and skin, and direct contact should be avoided. If contact occurs, it should be immediately washed with plenty of clean water and medical help should be sought3. Fire and explosion prevention: Although cyanamide superfine powder is non-flammable under dry conditions, it is still necessary to keep away from fire and heat sources during use, explosion-proof ventilation systems and equipment, and avoid generating smoke.

Storage conditions: The storage period of cyanamide superfine powder is 6-12 months, it should be stored in a dry, well-ventilated place, avoiding contact with strong oxidants and acids. Amount of curing agent to be added: In the of use, the addition amount of cyanamide superfine powder curing agent is usually 8-12% of the total resin weight, and the addition amount of promoter-A100 is 2-4% of the total resin weight. If the curing process needs to be accelerated, the proportion of promoter can be increased first, then the proportion of curing agent can be adjusted. Emergency treatment: In case of leakage, sand or other non-combustible adsorbents should be to mix and absorb, and then collected and transported to the waste disposal site. It can also be washed with a large amount of water, and the diluted wash water is put into wastewater system.

In summary, when using cyanamide superfine powder, it is necessary to strictly follow the safety operation procedures, take necessary protective measures, and ensure safety during use.
