Optifuse
Optifuse is a light diffusion coating for greenhouses that diffuses incoming light while keeping a high transmission of grow-light. It is cleaned off with Topclear Fuse, the Sudlac cleaner designed for that purpose.
Optifuse is highly wear resistant and goes onto the outside of glass and plastic greenhouses. Studies show that diffuse light has a beneficial effect on production, quality and crop growth. The coating is recommended in regions with a moderate temperature, while Optifuse IR takes over in warmer regions.
Optifuse spreads the light across the whole plant
Optifuse delivers a very high diffusion rate while keeping light loss to a minimum. Incoming light is diffused and reaches every leaf of the plant, high and low, which improves photosynthesis and transpiration. Humidity and temperature are better regulated, with a better CO2 level inside the greenhouse.
Optifuse must be diluted with water before it is sprayed onto the greenhouse. For optimal diffusion it is preferably applied by machine, so as to reach an even spread.
light transmission
At the reference dilution, Optifuse lets grow-light through almost in full, with a PAR transmission of 99%.
diffusion
At the same dilution, Optifuse diffuses incoming light throughout the greenhouse, for a diffusion rate of 85%.
application methods
Optifuse goes on by machine, by hand, by drone or by helicopter, which leaves a choice of 4 methods depending on the equipment available.
Optifuse is a milky liquid diffusion coating, supplied in 15 kg buckets. It is designed for outside application on glass and plastic roofs. For professional use only.
Application is preferably done by machine, so as to reach an even spread, and remains possible by hand, by drone or by helicopter. Optifuse is diluted with clean water before spraying: 1,000 to 1,500 L of liquid per hectare by machine, 1,700 to 2,000 L by hand. The reference dilution, 13 buckets and 1,000 L of water for 1,200 L of liquid per hectare, gives 99% light transmission and 85% diffusion.
We recommend applying Optifuse in the following conditions:
- An outside temperature between 10 and 30 °C
- A wind speed below 2 m/s (7 km/h)
- For fast drying: relative humidity (RH) < 80%
- Do not apply Optifuse to a wet surface or when rain is forecast within 6 hours
Optifuse is cleaned off with Topclear Fuse, at the moment the grower chooses. Cleaning calls for at least 240 L of Topclear Fuse per hectare, diluted in 1,260 to 1,760 L of water, depending on the application method. Topclear Fuse is applied when substantial rain is forecast within the week, as the rain washes the coating away. It goes neither onto a wet surface nor during rain.

Frequently asked questions
Optifuse is a diffusion coating for greenhouses that diffuses incoming light without losing it. It is designed for outside application on glass and plastic roofs, in regions with a moderate temperature. The grower adjusts the dilution and the application method, then cleans the coating off with Topclear Fuse whenever needed.
Diffused light reaches every leaf of the plant, high and low, which improves photosynthesis and transpiration. Studies show a beneficial effect on production, quality and crop growth.
At the reference dilution, Optifuse reaches 85% diffusion and lets 99% of the grow-light through. That dilution means 13 buckets and 1,000 L of water, for 1,200 L of liquid per hectare in machine application.
Optifuse goes onto the outside of any greenhouse type, on glass and plastic roofs alike. It is recommended in regions with a moderate temperature, while Optifuse IR is meant for warmer regions.
Application is done by machine, by hand, by drone or by helicopter, on a clean and dry roof. The machine is preferred, as it gives a more even spread and limits product loss.
Optifuse is cleaned off with Topclear Fuse, at the moment the grower chooses. Cleaning calls for at least 240 L of Topclear Fuse per hectare, diluted in 1,260 to 1,760 L of water, depending on the application method. Topclear Fuse is applied when substantial rain is forecast within the week, on a dry roof.
