INSTRUCTION FOR USE

♦ Ready-to-use mixtures (of the components A and B) are fed directly to the injection molding machine from the original containers by means of a metering and mixing unit. The mixture, consisting of the two components in the ratio 1:1, is injected into the heated mold. At mold temperatures of 140-200°C, the mixture cures within a few seconds with no byproducts. High curing speed and ease of demolding permit fully automated production of large numbers of articles in short cycle times.

♦ Although the viscosity of the mixture will be increased without heating, it can be injected for three days at 25°C. When stopping the machine for more days, clean the residual substance in the equipment with an appropriate solvent.
