People have always tried chemical deburring, however the results were never sufficiently suitable to prove economic or sensible for industrial purposes.

The reasons are the following: The efficiency was missing, and an enormous amount of creep builds up which has to be cut off at considerable costs. Apart from this the complete chemical material has to be disposed of, and new material has to be filled in. For this refilling process the complete plant has to be brought to a standstill which is by no means an economic way of operation.

This does not happen with the CULLYGRAT® process, and apart from that a further advantage is that colour changes on weld seams will also be removed.

The surprisingly constant for constant concentration of CULLYGRAT ® , with enormous strain has been confirmed by an international working institution. For 12 years we shall have the perfection of CULLYGRAT ® to the test.
