Puralact® B3 sustainable lactide monomer for coating resins

Summary:

PURALACT® B3 is a unique, high purity cyclic di-ester monomer based on L-lactide. PURALACT® B3 will undergo a ring opening reaction in the presence of  hydroxyl groups (initiator) and a catalyst, producing a 2° hydroxyl - and acid-group, to be built into resins.


Description:

PURALACT B3 in polyester, polyester polyols and alkyd resins allows to obtain viscosity reduction and higher yield. In the paint, PURALACT B3 helps to lower VOC by reducing the need for solvents, to reduce drying time  and improved toughness. The use of PURALACT B3 reduces the carbon footprint of the paint.
