Description

(54) MARKING COMPOSITION FOR OFFSET PRINTING Hardened tep13,7-33,3 Diaietone alcohol Else. Resins E-40, ED-2O, and E-41 are used as the diane epoxy resin; as a polyamide hardener, it is used in composite materials; a) resin PO-2OO (versamide), which is a condensation product of dimerized methyl acids of vegetable oils and polyethylene amines with amine number 18 O-21.0; b) resin PO-ZOO, which is a product of condensacin dim igyuvan. methyl methyl ester acids of vegetable oils and polyetheltopiamshyuv with an amine number of 280-31O; c) a mixture of a polyamide hardener with an amine adduct; Hardener B1 is a solution of a polyamide resin and an amine adduct UE-06-2O in a mixture of organic solvents. The amine adduct UP-O6-2O is a 65% solution of adduct B in diethylenetriamine. In the composition; The following types of mineral oils are used: transformer, instrument and petrolatum. The marking composition is a two component system; the floor

The mixture of components produced before use. The prefabricated marking composition is prepared as follows. The epoxy resin is heated in a mixer at a temperature of the heat carrier 5 ° С to a homogeneous mass, then in the last addition of diacetone alcohol and turn on the stirrer. Stirring is carried out until a uniform epoxy resin solution is obtained. After that, while the mixer is running, the remaining components included in the recipe of the semi-finished product are loaded Mark39, 1439.84
