 High technology formula. This formula is characterized by its special binding system with exceptional temperature and chemical attack resistance.
 The high temperature heat treatment required in the manufacturing process develops a primary shape contraction reducing the shrinkage level of the working shape.
The homogeneous and organic free compound helps to easy machining of the shapes without the use of special tooling. |
