MA-223U is a difunctional primary amine. Its mainchain is consisted of repeating oxypropylene units. The average molecular weight of MA-223U is about 230. MA-223U is a clear liquid with amine-like odor. It is ideal for use in epoxy curing agents, adhesives and surfactants.

WANNATE HMDI is used in the manufacture of polyurethanes and polyisocyanate. Main applications are polyurethanes waterborne dispersions, PU elastomers, UV urethanes acrylates, leather and textiles finition treatment. WANNATE HMDI‘s cycloaliphatic structure enables high transparency and good mechanical properties end products.

WANNATE IPDI is a cycloaliphatic diisocyanate and as such a prefered raw material for the the synthesis of lightstable and water-risistant polyurethanes. It is a low-viscosity liquid with a week but specific odour.

PMDA is a chief material for high temperature insulant, used mainly for the producing of polyimide resin, thin film, and insulating paint. It is also a high temperature curing agent and plasticizer. Some kinds of curing agents of powder coating are made from it.
