Diamine Cure 3 (Functional Equivalent DAIK 3) for FKM & ACM | Buy Online

Product Overview

Diamine Cure 3 is a blocked polyamine vulcanizing agent, functionally equivalent to DAIK 3 and Viton® Curative No. 3 (VC-3). It is specifically designed for the crosslinking of fluoroelastomers (FKM), polyacrylates (ACM), and ethylene acrylic elastomers (AEM). Characterized by its cinnamon-like odor and tan physical form, this curative provides exceptional processing safety due to its delayed action, which helps reduce scrap rates during milling and shaping. While offering slightly different final vulcanizate properties compared to unblocked diamines, Diamine Cure 3 provides a balanced profile of tensile strength and tear resistance, making it a versatile and safer-to-handle choice for manufacturing high-performance rubber goods.

Key Benefits

Enhanced Scorch Safety: As a blocked diamine, it offers significantly better processing safety compared to unblocked diamines like DAIK 1, allowing for more complex shaping and reducing the risk of premature cure (scorch) during mixing.
Processing Aid: Exhibits a slight plasticizing effect during mixing, which can aid in filler incorporation and improve the processability of the compound.
Good Physical Properties: Produces vulcanizates with excellent tensile strength at elevated temperatures and good overall tear strength.
Reliable Crosslinking: Effectively cures copolymer and terpolymer types of fluoroelastomers (FKM) to achieve durable, heat-resistant end products.

*Key Differences between DAIK 1 and DAIK 3: *

Processing Safety: DAIK 3 offers superior scorch safety and processing stability compared to DAIK 1. DAIK 1 is faster curing but has the least processing safety.
Vulcanizate Properties: DAIK 1 typically yields better compression set resistance and, in some polymers, higher original tensile strength. DAIK 3 provides a good balance of properties with excellent processing characteristics.

Applications

Industry: Rubber manufacturing, automotive, aerospace, industrial sealing.
Process Level: Compounding of fluoroelastomers (FKM), polyacrylates (ACM), and ethylene acrylic elastomers (AEM).
End Products: O-rings, gaskets, seals, hoses, and custom-molded parts requiring high-temperature resistance and chemical inertness.

Recommended Dosage

A satisfactory cure is typically achieved with approximately 3.0 parts per hundred rubber (phr) of Diamine Cure 3. It can also be used in combination with other curatives, such as 2 phr Diamine Cure 3 with 0.5 to 1.0 phr of an unblocked diamine (e.g., DAIK 1 type).
“Recommended dosage may vary based on formulation and processing conditions. Users should verify dosage before commercial use.

Available Pack Sizes

Diamine Cure 3 is available in a 500 grams pouch. We also supply in larger pack sizes to meet commercial requirements. We deliver pan-India and have tie-ups with all major couriers and transporters to ensure timely delivery.

Storage Conditions

Store in a tightly sealed container in a cool, dry, and well-ventilated area, ideally below 23°C.
Keep away from heat, sparks, and open flames as dust may form flammable mixtures.
Avoid breathing dust and avoid contact with skin and eyes. Use with adequate ventilation. Wash thoroughly after handling.
Shelf life is typically 24 months from the date of manufacture. Retest before use after this period.
