UNISET A20 is a member of new generation ester cured alkaline phenolic no‐bake
sand binders, designed for high mechanical strength, easy breakdown after pouring and
superior surface finish for castings.
High bench time to strip time ratio provides cores and moulds less vulnerable to
alterations in application, low resin ratios and a better working environment for the
foundrymen. Since UNISET A20 is developed with low inorganic alkaline content without
compromising strength values, foundries can achieve a higher yield on reclaimed sand.
With its superior mixing properties, UNISET A20 provides the same strength all over the
mould. For a better working environment and a cleaner casting, UNISET A20 is designed
to have low gas emissions.
Materials can be packed in steel drums and plastic IBC’s.
All products are produced in our ISO 9001:2015 certified plant in Gebze / TURKEY.
*For high alloy and stainless steel castings, a nitrogen and solvent free version coded
UNISET A20P can also be supplied to decrease the possibility of gas defects.
