Epoxy Applications

Industrial and Marine Coatings:

MultiTech Multifunctional F amine provides good metal adhesion, chemical & corrosion resistance, and toughness for demanding industrial and marine applications.

Decorative Coatings:

MultiTech Multifunctional F amine imparts a high gloss, low blush, uniform finish and improves UV stability compared to alternative amines.

Low Temperature Curative:

MultiTech Multifunctional F amine’s 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 MultiTech Multifunctional F amine can reduce gel time while maintaining key mechanical properties of final product.

Epoxy Curatives

Epoxy resins cured with MultiTech Multifunctional Fmines have excellent properties for use in coatings, civil engineering, adhesives, marine, and composite applications. 

Features	Typical Applications
Low viscosity vs. IPDA Chemical resistance Highest Tg of all MultiTech Multifunctional Fmines	Tank linings with chemical exposure High temperature applications Wind turbine blades High-performance composite parts

High Performance Polyamides

MultiTech Multifunctional F amine 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.

In addition, MultiTech Multifunctional F amine 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.

Hot Melt Adhesives

MultiTech Multifunctional F 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.

Other 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.

Polyurethane and Polyurea

MultiTech Multifunctional F amine is used as a chain extender in polyurethane applications. Differential reactivity due to the methyl substituent influences cross-linking and crystallinity.

MultiTech Multifunctional F amine derivatives such as secondary amines, aspartic esters, ketoimines and aldimines can be used as curatives in polyurea systems.

The diisocyanate from MultiTech Multifunctional F amine can impart unique properties to elastomer and sealant formulations.
