Product Introduction

Dicyandiamide (CAS 461-58-5), widely known as DCDA, is a premium-grade (99.5% content) nitrogen-rich compound essential for sophisticated chemical synthesis. It serves as the primary feedstock for producing guanidine salts and melamine-based resins. In industrial manufacturing, DCDA is prized for its "latent" curing properties, making it a critical additive in high-stability adhesives and powder coatings. Its dual role as a functional filler in artificial leather and a precursor for fire-resistant chemicals makes it a versatile solution for manufacturers seeking to enhance product durability and safety compliance.

Product Selling Points

1. High-Precision Synthesis Quality

• Advantage: Consistent 99.5% purity with ultra-low calcium and ash content.

• Benefit: Reduced Production Downtime: Minimizes side reactions and catalyst poisoning in pharmaceutical and resin synthesis, ensuring batch-to-batch consistency for large-scale industrial users.

2. Optimized Latency for Formulations

• Advantage: Acts as a latent hardener that only activates under specific heat profiles.

• Benefit: Extended Shelf Life: Allows manufacturers of one-part epoxy adhesives and prepregs to offer products with longer storage stability at room temperature without premature curing.

3. Superior Logistics Efficiency

• Advantage: Flexible packaging (25kg/500kg) and high-density loading (up to 21 MT per FCL).

• Benefit: Lower Unit Costs: Maximizes container space and reduces per-kilogram shipping costs, providing a significant competitive edge in global procurement.

Applications

Chemical Intermediates

Primary raw material for the production of guanidine amine, double condensed guanidine, and melamine resins.

Epoxy & Adhesives

Used as a latent curing agent in powder coatings and a high-performance additive to increase bond strength in structural adhesives.

Flame Retardants

An essential nitrogen source for manufacturing halogen-free flame retardants used in plastics and textiles.

Synthetic Leather

Functions as a specialized filler in artificial leather production to improve texture, durability, and fire resistance.

Packaging & Logistics

• Standard Packaging: 25kg net weight in plastic woven bags with PE inner liner; or 500kg ton bags.

• Loading Capacity (20' FCL):

  • 21 MT per 20' FCL (without pallets).

  • 18 MT per 20' FCL (with pallets).

• Storage: Store in a cool, dry, and well-ventilated area. Crucial: Ensure moisture-proof storage. DCDA must be kept away from strong acids and oxidizing agents to maintain its chemical integrity and prevent caking.

FAQ

Q: How do you guarantee the purity for high-sensitivity resin applications?

A: Every batch undergoes HPLC testing to ensure 99.5% minimum assay. We specifically control calcium and moisture levels, as these are critical for preventing unwanted side reactions in epoxy curing and pharmaceutical synthesis.

Q: We face caking issues with DCDA during sea transit. How do you solve this?

A: Caking is usually caused by moisture absorption or high pressure. We use high-quality PE inner liners and moisture-proof woven outer bags. Additionally, for long-haul sea freight, we recommend our 25kg bags loaded without over-stacking to ensure the material remains free-flowing upon arrival.

Q: Is your DCDA suitable for one-part (1K) epoxy systems?

A: Yes. Our 99.5% grade offers the thermal latency required for 1K systems. It remains stable in the resin at room temperature but provides rapid cross-linking once the activation temperature (typically 160°C+) is reached.

Q: Can you provide customized particle sizes (Micronization)?

A: For standard industrial orders, we provide crystalline powder. However, we understand that dispersion is key for adhesives and coatings. Please specify your required mesh size (e.g., <10μm or <40μm), and we can provide micronized DCDA to ensure perfect dispersion in your formulation.

Q: Does your product comply with environmental regulations for leather exports?

A: Our DCDA is produced under strict ISO guidelines. It is free from restricted heavy metals and serves as a safer, halogen-free alternative in flame retardant formulations, helping your final products meet REACH and RoHS standards.
