Processing

Components A and B are delivered ready to use in drums of 20 and 200 liters capacity. They can be pumped by means of standard metering equipment from these drums and mixing in a static mixer straight into the heated mold. The mixing ratio is 1 : 1. At room temperature, mixtures of A and B components have a pot life of at least three days.
