IOTA 6ND742 is a solvent-free liquid silicone resin containing abundant anilinomethyl, alkoxy, and other reactive groups. The amino and alkoxy contents can be regulated, and other active group types can be selected based on application requirements.
Its molecular structure features a secondary amino functional group and numerous reactive alkoxy groups. This dual reactivity enables IOTA 6ND742 to undergo bidirectional chemical reactions with both inorganic materials (glass, metals, fillers) and organic polymers (thermosetting resins, plastics, elastomers), significantly improving bonding, adhesion, and compatibility between the two. This enhances the mechanical properties of resin matrix composites or improves coating adhesion strength and water resistance.
In different applications, IOTA 6ND742 can serve as a coupling agent, adhesion promoter, curing agent, or surface modifier for pigments and fillers.

IOTA 6ND742 contains two types of reactive groups:
Secondary amino (-NH-) – reacts with epoxy, isocyanate, anhydride, and other organic functional groups for chemical bonding with organic polymers
Alkoxy (-OR) – hydrolyzes to silanol, which condenses with hydroxyl groups on inorganic surfaces (glass, metals, fillers) to form stable Si-O- bonds
Through this "organic-inorganic" dual bridging, IOTA 6ND742 forms strong chemical bonds at interfaces, significantly improving interfacial bonding strength and durability of composite materials.
