Vancouver, B.C.: Homerun Resources Inc. (“Homerun” or the “Company”) (TSXV: HMR) (OTCQB: HMRFF) is pleased to announce the key technical and strategic highlights of a patent application for a novel, antimony-free soda-lime-silica glass composition designed specifically for photovoltaic solar panels and high-transparency industrial applications. Utilizing high-purity silica produced through a proprietary purification process, this advanced formulation eliminates the need for antimony-based refining agents while achieving exceptional optical clarity.
STRATEGIC SIGNIFICANCE IN THE SOLAR GLASS INDUSTRY
As global photovoltaic installation accelerates, environmental regulations surrounding solar module manufacturing and end-of-life disposal have tightened significantly. Traditional high-transparency solar glass relies heavily on antimony trioxide (Sb₂O₃) as a clarifying agent to eliminate air bubbles during glass melting. However, antimony presents severe environmental leaching risks when decommissioned modules are discarded in landfills.
Key Strategic Advantages:
- Elimination of Environmental Contamination Risks: By completely removing antimony from the vitreous formulation, the patent meets restrictive international environmental standards and mitigates toxic heavy metal leaching into soil and water ecosystems.
- Sulfur Trioxide (SO₃) as an Advanced Clarifying Agent: The formulation replaces antimony with controlled sulfur trioxide content (0.30% to 0.60% mass fraction), effectively removing bubbles during the melting process without compromising mechanical strength or light transmission.
- Ultra-Low Iron Content Without Chemical Bleaching: Leveraging high-purity purified silica yields ferric oxide (Fe₂O₃) levels below 0.020% (and below 0.012% in preferred formulations). This removes the historical requirement for chemical bleaching agents to maintain solar transmittance.
- Seamless Industrial Compatibility: The soda-lime-silica composition retains standard physical-chemical properties, making it fully compatible with existing commercial float glass production lines on an industrial scale.
CHEMICAL COMPOSITION & TECHNICAL SPECIFICATIONS
The high-purity glass formulation incorporates optimized mass fractions of silica, fluxing agents, and stabilizing agents. Due to the high degree of purity and quality of the silica, a specific composition is achieved that enables the production of highly transparent glass. The reference parameters for the patent claim are set forth in application PCT/BR2026/050512, which will be published in the “Revista de Propriedade Industrial” (Industrial Property Gazette) of INPI Brazil.
While optimized for photovoltaic solar panel encapsulation, the high optical transmittance and pristine purity profile render this glass composition highly versatile for demanding industrial sectors, including architectural float glass, high-efficiency optical components, electronic display covers, and automotive applications requiring extreme clarity and environmental sustainability.
