Foundry Binder PUROLiT

Our ecological binding agent

Casting techniques and methods are of central importance to high-quality engineering. Dimensional stability and low tolerances are therefore an important prerequisite for the casting process. Up until now, large quantities of organic and inorganic binding agents are used, releasing odorous and harmful emissions during moulding and casting, respectively. The disposal of used foundry sands as highly contaminated hazardous waste is an additional problem.

In accordance with our philosophy of using renewable and non-hazardous raw materials, we developed for the first time an organic binding agent that is not only non-toxic, but also easy to apply. Our development in collaboration with TU Bergakademie Freiberg and experienced foundry partners has demonstrated the ease of use and high reliability of our product. It can be used for the mould production by hand as well as in automated core shooting.

The binder PUROLiT consists of two components (resin and hardener). Its reaction rate is controlled by a catalyst. Our binding agent is almost odorless, low in emissions and therefore safe to handle. In addition to the processing-friendly characteristics, it shows a high stability.

Eligible studies of established laboratories show that the environmentally benign properties, qualify the discharged core sands, in accordance to the landfill ordinance, as non-hazardous waste.

We have the first powerful organic binding agent available that is designed to cater for safe and cost-effective foundry operation.
