The UHS technological evolution, after the introduction of the Directive 2004/42/CE, has produced during the last 5 years the development of new products and, consequently, the introduction of specific hardeners.

A Lechler team of technicians and product managers have worked during the last few years, on a program for the rationalisation of hardeners, to simplify the body repair users work with respect to the performance requirement of each product.
The Multiprogram UHS Hardners are completed: all the Macrofan System hardeners (slow, standard, fast, ultra fast) can now be used with UHS Clearcoats, and with all the Macrofan System topcoats (MAC4, MAC14-15-16) and fillers, even for fillers in ready for use colours.
The use of our UHS hardeners allows users to maintain the products performance, with respect to the limits of maximum VOC concentration recommended by European legislation.

Furthermore Lechler has made an up-to-date version of the  Multiprogram Navigator, to enable hardener selection. It is a small book with all the possible combinations of product/hardener/thinner: a simple and smart consultation tool divided by product code. For each code the user will find the quality and the quantity of hardeners and thinners which can be used.
