Ultrafine dicyandiamide, also known as latent curing agent of epoxy resin, 1-cyanoguanidine.
Molecular weight: 84.08 Structural formula:
CAS # 461-58-5
Packing: packed in 15kg cartons.
Purpose:
Dycure10 is used as a latent curing agent in thermosetting epoxy resin system, in which less than 1.6% dispersant is added to prevent product caking and promote the even dispersion of Dycure10 in epoxy resin system. It is widely used in the field of one-component adhesives, composite materials and powder coatings.
Product specification:
Appearance: white powder
Dicyandiamide content (HPLC): ≥ 97.3%
Dispersant: ≤ 1.6%
Moisture: ≤ 0.3%
Particle size D90: 90%<10 μ m
Dycure 10 is an ultra-micronized grade of dicyandiamide containing 1.5% of anti-blocking agent to prevent clomping and improve application. It is designed for use as a latent curing agent for epoxy resins.
Appearance: Free flowing white powder.
Advantage:
1. Fine particle size provides enhanced reactivity versus coarser grades.
2. Easily dispersed in liquid resins.
3. Shelf stability up to 6 months at 25 ° C in properly formulated systems.
4. Activation temperature can be easily varied from 180° C to 100° C with appropriate accelerator selection.
application:
1. One component adhesives
2. Epoxy powder coatings
3. Prepregs and film adhesives
4. Electronic potting and encapsulating compounds
Storage life: At least 12 months from the date of manufacture in the original sealed container at ambient temperature. Store away from excessive heat and humidity in tightly closed containers.
