ASK CHEMICALS INTRODUCES NEW ENVIRONMENTALLY FRIENDLY POLYURETHANE BINDER SYSTEM FOR SELF-CURING
PEP SET systems are appreciated by many foundries for their processing properties, very good casting results and high productivity. With the newly developed PEP SET SILVER, ASK Chemicals is now expanding its product range in the field of polyurethane no-bake technology with a new generation of PEP SET binders which allows a reduction of phenol and formaldehyde emissions without having to give up the advantages of casting technology.
With the help of a new, cutting-edge production process, ASK Chemicals has succeeded in reducing the proportion of monomers in the formulation. In particular, the proportion of monomeric phenol was reduced by approximately 5 % to below 1.0 %. This improvement naturally also has a positive effect on the phenol concentration in the molding mixture and the regenerate as well as minimizing related odors.
