Toluene diamine (TDA) is a aromatic diamine used for the production of polyurethane foams

Toluene diamine (TDA) is an organic compound that is commonly used in the production of polyurethane foams, coatings, adhesives, and elastomers. It is a member of the family of aromatic diamines, which are important building blocks for the production of various chemicals and materials. It is prepared by the hydrogenation of dinitrotoluene. TDA is used as a curing agent in the production of polyurethane foams, coatings, adhesives, and elastomers. The reaction between TDA and polyols or other isocyanates results in the formation of a polyurethane network, which provides the desired properties such as strength, flexibility, and insulation. TDA is also used as a crosslinking agent in the production of epoxy resins, which are commonly used in the aerospace, automotive, and electronics industries.

Metalyst® MC

Metalyst® products are activated metal catalysts based on nickel, cobalt or copper which are utilized in hydrogenation reactions. These products are delivered either in water or as embedded material in distearylamine (DSA) or polyethylene glycol (PEG) for water-free processes. These products are sold worldwide for the manufacture of polyols such as sorbitol, for fatty amines in the care specialties industry and for industrial chemicals (e.g. 1,4-butanediol and toluene diamine).
