TEGOAMIN 33

TEGOAMIN 33 is a solution of 33 % triethylene diamine in dipropylene glycol which is used as a catalyst for the manufacture of polyurethane foams and polyurethane elastomers.

Application

TEGOAMIN 33 contains triethylene diamine which for quite some time has been counted among the standard catalysts for the production of polyurethanes. Thanks to its unique catalytic performance it accelerates both the isocyanate/ water reaction and the isocyanate/polyol reaction and hence it is a suitable and important catalyst for the entire field of polyurethane processing.

The well-balanced, uniform acceleration of both reactions makes this amine an outstanding catalyst which improves production safety and at the same time ensures a wide processing latitude.

TEGOAMIN 33 has been proved particularly suitable for the production of conventional flexible foams (slabstock and molded foams) and also in formulations for cold cured (HR) foams (slabstock and molded foams). Further fields of application are rigid polyurethane foams, microcellular foams and polyurethane coatings and elastomers. The examples for application given in this leaflet refer mostly to the use of TEGOAMIN 33 in formulations for conventional flexible foams and cold cured (HR) foams.

Application in Flexible Hot Cured Foams

In conventional formulations for flexible foams this amine catalyst above all improves the production safety and definitely reduces the tendency to foaming defects like for example the formation of splits during the foaming procedure. In formulations which contain physical blowing agents TEGOAMIN 33 enables the generation of open-celled and elastic foams and ensures fast curing and uniform density distribution. In formulations for foams in the density range between 20 and 30 kg/m TEGOAMIN 33 can be used as the only catalyst or combined with another amine which predominantly accelerates the isocyanate/water reaction, like e. g. TEGOAMIN DMEA.

In formulations for densities above 35 kg/m TEGOAMIN 33 should be used in combination with a co-catalyst which promotes mainly the isocyanate/water (blowing) reaction. Especially well suited are TEGOAMIN DMEA or TEGOAMIN BDE at a mixing ratio of e. g. 1 : 1 or 1 : 2.
