What Silox Canada does

Silox Canada is a privately held specialty chemicals manufacturer headquartered in Quebec, Canada, founded in 1996 (originally as Hydro Technologies (Canada) Inc.) and rebranded in 2022 upon becoming the strategic North American subsidiary of the Belgian Silox Group (Groupe Silox), with local minority partner Gestion Infilise Inc. The company operates a single manufacturing facility at 2324 rue Einstein, Quebec, producing two principal product lines: sodium hydrosulfite-based bleaching solutions marketed under the HY BRITE® brand (including the newly patented HY BRITE® Crystals form using an innovative pH and temperature-controlled crystallization process), and a comprehensive portfolio of zinc derivatives including active zinc oxide with high specific surface area (making Silox Canada the sole North American producer of this grade), ActiECO+ vulcanization activators, ZINECO, zinc carbonate, and zinc fine powder.

The company's core technology rests on proprietary chemistry in zinc and sulfur derivatives, with a patented (2022) sodium hydrosulfite crystal production process that combines advantages of solid and liquid forms while reducing transport, safety, and energy costs. Manufacturing operations achieve zero liquid and solid effluent through closed-loop water management. Silox Canada holds ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, C-TPAT, and USMCA certifications, and has accumulated a record of 2,382 days without a lost-time accident as of 2018.

Silox Canada sells directly to industrial enterprise customers via a technical field sales force with on-site accompaniment, process audits, and remote consumption monitoring. Revenue is generated through one-time product sales of specialty chemicals and custom formulations, with pricing not publicly disclosed. Primary end markets are pulp and paper (HY BRITE® bleaching solutions) and rubber/tires (active zinc oxide for EPDM applications), with secondary applications in textiles, ceramics, paints and coatings, personal care, animal and human nutrition, pharmaceuticals, fiber recycling, and household products. Distribution is concentrated in North America, with the patented HY BRITE® Crystals technology positioned to enable future international expansion.

Core offering

Silox Canada manufactures and sells inorganic specialty chemicals, primarily sodium hydrosulfite bleaching solutions (HY BRITE® range) and zinc oxide grades (ActiECO+, ZINECO), along with zinc derivatives such as zinc carbonate, zinc sulfoxylate, zinc fine powder, and sodium sulfoxylate. Its products serve as functional inputs for industrial manufacturers in pulp & paper, rubber & tires, textiles, paints & coatings, personal care, animal nutrition, ceramics, and related sectors. The company is the only North American producer of active zinc oxide with high specific surface area and holds patented technology for stabilized sodium hydrosulfite crystals.

Product overview

Silox Canada operates as a specialty chemical company offering two main product lines: (1) HY BRITE® brand sodium hydrosulfite-based bleaching solutions (including HY BRITE® Crystals with patented production technology) used primarily in pulp and paper applications, and (2) a comprehensive zinc derivatives portfolio including active zinc oxide (ZnO), regular ZnO, ActiECO+ vulcanization activators, ZINECO, zinc carbonate, and zinc fine powder. The company is the only North American manufacturer of high-specific-surface active zinc oxide, serving rubber/technical rubber, ceramics, personal care, paints/coatings, textiles, chemical, pharmaceutical, animal and human nutrition, and fiber recycling industries.
