Dytek® A (2-Methylpentamethylenediamine) by Invista acts as a chain extender in polyurethane applications. Its derivatives such as secondary amines, aspartic esters, ketoimines and aldimines can be used as curatives in polyurea systems. In polyamides, it acts as a crystallinity disruptor, making polymers more amorphous and slower to crystallize. It offers lower melting point, increased abrasion resistance, improved surface appearance and dye uptake. Dytek® A (2-Methylpentamethylenediamine) reduces gelling, water absorption, melt and quench temperatures. Dytek® HMI (Hexamethyleneimine) by Invista is a clear, colorless liquid with an ammonia-like odor. Dytek® HMI (Hexamethyleneimine) is used in rubber chemicals. Dytek® DCH-99 (1,2-Diaminocyclohexane) by Invista is a cyclic aliphatic diamine used in polyurethanes, polyamide and epoxies. It acts as an extender, corrosion inhibitor, catalyst, and chelating- and curing agent. It is a mixture of cis- and trans-isomers. Dytek® DCH-99 (1,2-Diaminocyclohexane) is suitable for films and plastics. Dytek® EP (1,3-Pentanediamine) by Invista is a low viscosity, low odor, liquid diamine featuring an odd carbon, ethyl branched, asymmetric structure and differential amine reactivity. Dytek® EP (1,3-Pentanediamine) is suitable for polyamide, elastomer, epoxy, urethane and plastics. Dytek® Hexamethylenediamine by Invista is a 99.9% pure aliphatic diamine, available from 70–100 wt% concentrations in water (in Europe, product is also available as 60 wt% solution). It acts as a curing agent and corrosion inhibitor. Dytek® Hexamethylenediamine is suitable for fibers. It is compatible with isocyanates, epoxies and polyamide resins. Dytek® BHMT-HP (Bis(hexamethylene)triamine) by Invista acts as an emulsifier, curing-, flocculating- and chelating agent. It is a solid aliphatic triamine that provides unique properties when used in a variety of amine applications including polyamides and epoxies. It is a polyurethane extender or catalyst. Dytek® BHMT-HP (Bis(hexamethylene)triamine) is suitable for films, plastics and wet strength paper resins. Dytek® 2-Methyl-3-Butenenitrile by Invista acts as an accelerator and lubricant. It is an unsaturated and unconjugated mononitrile. Dytek® 2-Methyl-3-Butenenitrile is suitable for rubbers. Triisopropyl borate. Used in polymer additives. Triisopropyl borate. Used in polymer additives. Triisopropyl borate. Used in polymer additives.
