HG/T 4755-2014 Polysiloxane Coatings is the Chinese chemical industry standard that defines the technical requirements and performance criteria for polysiloxane coating systems. The standard specifies key performance indicators, including but not limited to:

Focusing on modified polysiloxane technology, Quark New Material has independently developed Durle® Epoxy Modified Polysiloxane Resin, offering a high-solid, low-VOCs, safe, and low-carbon solution for the green transformation of industrial anti-corrosion coatings.

Quark Durle® polysiloxane resin leverages proprietary formulation technologies to supply compliant, long-service-life raw material solutions for heavy-duty anti-corrosion applications.

With the dual background of China’s “Dual Carbon” goals and the implementation of the new national standard GB/T 30981, the coatings industry is undergoing a profound green transformation. Traditional solvent-based coatings are facing mounting challenges: stricter VOCs regulations, rising safety costs, and growing health risks.
