DYTEK A Amine is a potential alternative to ethyleneamines (DETA, TETA, TEPA), TMD, and polyetheramines, bringing unique properties to products and formulations such as lower viscosity, increased flexibility, low-temperature curing, fast curing, and in polymers, less crystallinity.

2-Methylpentamethylenediamine (MPMD)

The two primary amine groups exhibit differential reactivity.

DYTEK® A Amine is manufactured from recovered and refined materials that would otherwise be burned with heat recovery, giving it a 93% recycle content.

Features & Benefits

• Lower viscosity
• Increased flexibility
• Low temperature and fast curing
• Less crystallinity in polymers
• 93% recycled content

Epoxy Applications:

• Industrial and Marine coatings: provides good metal adhesion, chemical & corrosion resistance, and toughness for demanding applications.
• Decorative coatings: imparts a high gloss, low blush, uniform finish and improves UV stability compared to alternative amines.
• Low-temperature curative: low viscosity and fast cure rate make it an excellent choice for low temperature application and curing.
• Accelerator: When used with slower curatives like polyether- or cyclo-aliphatic amines, small amounts of DYTEK A amine can reduce gel time while maintaining key mechanical properties of final product.

Polyurethane and Polyurea:

• Used as a chain extender in polyurethane applications. Differential reactivity due to the methyl substituent influences cross-linking and crystallinity.
• DYTEK® A amine derivatives such as secondary amines, aspartic esters, ketoimines and aldimines can be used as curatives in polyurea systems.
• The diisocyanate from DYTEK® A amine can impart unique properties to elastomer and sealant formulations.

Hot Melt Adhesives:

• DYTEK® A amine can be used as an alternative to hexamethylene diamine to lower melting point, improve thermal stability and flexibility, and allow for more open time.
• Aldimine derivatives can be used in moisture-cured polyurethane reactive hot melts.

High Performance Polyamides:

• Acts as a crystallinity disruptor, making polymers more amorphous and slower to crystallize.
• Potential benefits include lower melting point, improved surface appearance, reduced gelling, reduced melt and quench temperatures, reduced water absorption, improved dye uptake, and increased abrasion resistance.
• May allow for more versatility in polymer composition such as reducing the amount of isophthalic acid needed to maintain transparency or reducing total cost by allowing use of lower cost acids, such as terephthalic acid.

Additional Applications:

• Neutralizing or buffering agent: Typically does not produce insoluble salts.
• Metalworking fluids: Suppresses iron and amine discoloration, improves corrosion resistance and provides effective pH control, extends life by reducing formation of dark color and sediment.

Performance Data

DYTEK A shows low viscosity and low adduct viscosity for improved flow and leveling.
