UNISET A25 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.
With automatic moulding lines, even with lower addition ratios, even flaskless
moulds exhibit a higher strength which enables the use of a manipulator within short
intervals after stripping. With its superior mixing properties, UNISET A25 provides the
same strength all over the mould. For a better working environment and a cleaner casting,
UNISET A25 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 A25P can also be
supplied to decrease the possibility of gas defects.
