Hardener T 150

used in combination with epoxy resins for the preparation of two-component coating substances

Product characteristics

HARDENER T 150 is a modified blend based on adduct of polyalkylene polyamine and mid-molecular epoxy resin in a blend of organic solvents.


It is used in combination with epoxy resins for the preparation of two-component coating substances that get dry in air at normal as well as elevated temperatures.

Product features

HARDENER T 150 is yellow to yellow-brown mid-viscous liquid insoluble in water. It is sensitive to an influence of the air humidity

Product manufacturing

HARDENER T 150 is miscible with solutions of epoxy resins and epoxy coating agents. Curing of the blend processes at 20 oC, however can be quickened by the use in temperatures up to 100 oC. HARDENER T 150 is soluble in solvent blends such as xylene-butanol 4:1, toluene-acetone 4:1. It is also partially soluble in toluene, xylene, white spirit, acetone and butanol. HARDENER T 150 is mixed up for instance with EBOLIT 102 in proportion of 1:2 shortly before the use. Both of these components are mixed up properly and the varnish is diluted to a consistency suitable for brush painting, overspray, eventually wetting. The varnish usability containing HARDENER T 150 is only limited to 10 – 18 hours. Later on, the varnish is getting thicker and application is difficult. Gel-like particles originate and deteriorate quality of skin of paint. To prevent losses of coating agents the only partial quantity of varnish is recommended to prepare. This limited quantity can be utilized within the only working shift then. Two-component varnishes cured by HARDERNER T 150 are suitable for wood-surface treatment, wood-fibre boards, metals, walling, concrete and some kinds of plastic masses. Coatings feature good chemical resistance and stability up to 80 oC.
