Petrex distributes Graf Chemie silicone emulsions in Bulgaria, Romania, and the wider region, providing manufacturers in the construction and coatings industries with reliable water-repellent additives. These polysiloxane-based emulsions ensure long-lasting hydrophobic protection by reducing capillary water absorption while preserving natural breathability. Used in facade coatings, plasters, and drymix formulations, silicone emulsions protect against algae and mould growth, frost damage, and efflorescence, helping buildings remain both durable and visually attractive over time.

Through our cooperation with Graf Chemie, Petrex delivers advanced solutions that enable producers to create coatings and construction systems with superior durability, energy efficiency, and sustainability. By keeping building materials dry, silicone emulsions improve thermal insulation, lower energy consumption, and extend maintenance cycles. With proven product lines such as Silsan®, we provide our clients in the region with high-performance facade protection technologies that meet modern technical and environmental standards.
