New group of growers has greenhouse coating applied

Growers in the Netherlands are having a special coating applied to the inside of their greenhouses. The fully natural, transparent, water-based coating was developed by inventor Jaap van der Spek and is marketed by Multipurus, the new name for what was formerly Multi-Cover.

The company’s approach is continuous, deep cleaning of surfaces and air through photocatalysis, explains Koos Evenblij. “Algae, mold and particulate matter are removed in a continuous process, and nitrogen is cleared away as well.” The coating is applied across the entire greenhouse roof using a newly developed cart-mounted system.

Coating works with daylight against algae
Multipurus focuses on sustainability and long-term performance over a period of years, Koos emphasizes. “According to several published scientific studies, photocatalysis ranks second only to sterilization at 360°C (680°F) in cleaning power. The coating is completely inert and does not react with its surroundings. The photocatalytic process is activated by daylight. That’s a major advantage when you consider that no chemicals and no labor are involved.”

Multipurus makes scientific reports available on the effects of photocatalysis on mold, bacteria and viruses, among other things. The reports can be accessed in the knowledge base on the Multipurus website. The site also provides information on the coating’s secondary effects, such as a substantial gain in light and temperature, Koos notes. “These are additional benefits that offer significant advantages to the industry.”
