What Kastus Technologies does

Kastus Technologies Company Limited is an Irish materials science company founded in 2014 and headquartered in Dublin that develops photocatalytic and hydrophilic surface treatments for glass. Its core technology is a water-based titanium dioxide (TiO2) anatase nanotechnology solution applied to glass before the tempering process and sintered into the surface during firing, producing a permanent, non-leaching coating that is simultaneously photocatalytic (using UV light and oxygen to break down organic contaminants into water and CO2) and hydrophilic (spreading water to wash away inorganic dust). The company commercializes this platform across three product lines: Kastus Solar (permanent anti-soiling treatment embedded into solar cover glass during manufacturing, addressing the IEA-estimated $3.2 billion in annual solar panel efficiency losses from soiling), Kastus Clean Rooms (antimicrobial coating killing up to 99% of bacteria and viruses on glass surfaces, distributed via Daldrop's clean room channel), and Kastus Automotive (antimicrobial and anti-soiling treatment for interior touch screens, sensors, sunroofs, mirrors, and exterior glass). The technology is validated to maintain Visible Light Transmittance above 94% even over double anti-reflective coatings and is independently validated by the Fraunhofer Institute, which projects 1%–3% energy yield improvements for treated panels.

Kastus operates a B2B OEM-embedded licensing model: solar panel and solar glass manufacturers integrate the technology into their mass production lines during the glass tempering process with no significant process changes required, generating revenue through licensing fees or per-unit royalties negotiated with OEM partners. The company also engages directly with solar farm developers and operators for validation partnerships and early adopter programs, and distributes Clean Room technology through a channel partnership with Daldrop, a clean room specialist with 10,000+ installations globally. Kastus holds 52 worldwide patents, 10 ISO validations, 8 global certifications, and ISO 9001 certification, and is backed by Enterprise Ireland, Atlantic Bridge, and Ascent, with total disclosed funding of approximately $11.75 million across three rounds between 2016 and 2021. The company is led by founder and CEO John Browne alongside CTO James Kennedy, COO Gavin Denn, CFO John Tyler, and Head of Sales Daniel Misturini, and is currently active in Europe and China, including a 2025 strategic collaboration with LONGi Solar and participation at SNEC2025 in Shanghai.

Revenue model

1. OEM/Licensing to Solar Panel Manufacturers: Kastus licenses its technology to solar panel and solar glass manufacturers who embed the solution into glass during the manufacturing tempering process. Manufacturers integrate the technology with no significant changes to production lines. Revenue is derived from licensing fees or per-unit royalty arrangements negotiated with OEM partners.
2. Strategic Clean Room Partnerships (Daldrop): Partnership with Daldrop to bring Kastus Clean Room technology to market globally, leveraging Daldrop's 43+ years of experience and over 10,000 clean room installations.

Core offering

Kastus Technologies develops and licenses a proprietary TiO2-based photocatalytic and hydrophilic surface treatment that is sintered permanently into glass during manufacturing. The technology is sold to solar panel, solar glass, clean room, and automotive glass manufacturers as an embedded OEM solution, delivered through three branded product lines: Kastus Solar (anti-soiling), Kastus Clean Rooms (antimicrobial), and Kastus Automotive (antimicrobial interior glass and anti-soiling exterior glass).

Product overview

Kastus Technologies offers a portfolio of Clean Glass Technologies based on photocatalytic and hydrophilic nanotechnology. The core technology employs TiO2 (titanium dioxide anatase) which is sintered into glass surfaces during manufacturing. The product portfolio consists of three main offerings: Kastus Solar (anti-soiling solution for solar panels), Kastus Clean Rooms (antimicrobial coatings for clean room glass), and Kastus Automotive (antimicrobial and anti-soiling for automotive glass). All products leverage the same fundamental nanotechnology platform - a permanent, durable surface treatment that is photocatalytic (using UV light and oxygen to break down organic matter) and hydrophilic (attracting water to prevent beading and remove contaminants).

Products and services

• Kastus Solar Permanent anti-soiling surface solution for solar panels. The treatment is photocatalytic and hydrophilic, embedded into the glass during manufacturing tempering, preventing beading and repelling dust accumulation for the lifetime of the panel without re-application. For solar panel manufacturers and solar farm operators.
• Kastus Clean Rooms Antimicrobial surface treatment for clean room glass surfaces that kills up to 99% of bacteria and viruses including Human Coronavirus across every square inch of glass 24/7. Distributed globally through partner Daldrop, a clean room specialist with over 43 years of experience and 10,000+ rooms built. For clean room builders and operators in pharmaceutical, medical device, semiconductor, and research industries.
• Kastus Automotive Antimicrobial and anti-soiling solution for automotive glass components. Internal touch screens and infotainment glass benefit from antimicrobial protection killing up to 99% of bacteria and viruses. External glass surfaces (windshields, sensors, sunroofs, mirrors) benefit from photocatalytic and hydrophilic properties for self-cleaning and optimal sensor operation. For automotive OEMs and Tier 1 suppliers.
