Eclipse F4

Eclipse F4 is a temporary greenhouse shading coating that protects crops against excess light and heat for 2 to 4 months. It wears off gradually over the season and therefore needs no cleaning.

The shading rate, from 30% to 75%, is chosen at the dilution stage, and the coating goes onto any greenhouse type. Within the Sudlac F-series, Eclipse F4 stays a longer duration than Eclipse F2 and for less time than Eclipse F6. It is mainly used for ornamentals and leafy vegetables.

Eclipse F4 protects the whole season

Shading reduces stress and protects crops from excess light and heat, which improves productivity and quality. Eclipse F4 is a temporary coating that wears off over time.

It is mainly used to protect ornamentals and leaf or fruit vegetables such as tomatoes and peppers.

Eclipse F4 must be diluted with water before it is sprayed onto the greenhouse. It can be applied manually, by machine, by drone or by helicopter.

months of protection

Eclipse F4 delivers strong, reliable shading protection in the first weeks, then wears off gradually over the season and with the needs of the crop, to disappear completely after 2 to 4 months.

30-75%

adjustable shading

The dilution rate directly drives the shading rate. Three dilutions of Eclipse F4 give 30-35%, 50-55% or 70-75% shading, from light protection to heavy shading.

Product information

White shading coating, supplied in 20 kg buckets. Compatible with glass, polycarbonate and plastic film. For professional use only.

Dilution and application

Application is done manually, by machine, by drone or by helicopter. Eclipse F4 is diluted with clean water before spraying, for a total of 2,000 L of mix per hectare.

  • 10 buckets and 1,800 L of water gives 30-35% shading
  • 20 buckets and 1,700 L of water gives 50-55% shading
  • 30 buckets and 1,550 L of water gives 70-75% shading
Application conditions

We recommend applying Eclipse F4 in the following conditions:

  • An outside temperature between 5 and 30 °C
  • A wind speed below 2 m/s (7 km/h)
  • For fast drying: relative humidity (RH) < 80%
  • Do not apply Eclipse F4 to a wet surface or when rain is forecast within 12 hours
Cleaning

Eclipse F4 wears off gradually over the season and calls for no cleaning at the end of the season. The roof recovers its light transmission when the crop needs all available light. The duration of the product is customizable: Eclipse F2 for a shorter duration, Eclipse F6 for a longer one. If needed, Eclipse F4 can be cleaned off with Eclipse Net.

Frequently asked questions

What is the Eclipse F-series?

Sudlac's long-standing range and the result of years of development and optimisation, Eclipse F2, F4 and F6 are three shading coatings for greenhouses and tunnels, offering the same quality of protection over different durations. Growers therefore pick the protection time they want without having to clean the coating off at the end of the season.

Which crops is Eclipse F4 used for?

Eclipse F4 mainly protects ornamentals and leafy vegetables. It is also used on fruit vegetables such as tomatoes and peppers.

How long does the shading last?

Eclipse F4 stays for 2 to 4 months, depending on rainfall and solar radiation. For a different duration at the same shading level, Eclipse F2 covers up to 2 months and Eclipse F6 covers 4 to 6 months.

How is the shading rate set?

The shading rate is set at dilution, before spraying. Three reference dilutions cover 30-35%, 50-55% and 70-75% shading, for 2,000 L of liquid per hectare. The spraying liquid is prepared with clean water: 1,000 to 1,500 litres per 10,000 m² for machine application, 1,700 to 2,000 litres per 10,000 m² for manual application.

What types of greenhouse can it be applied to?

Eclipse F4 is applied on the outside of any greenhouse type, as well as on tunnels. The coating suits glass, acrylate, polycarbonate and plastic film.

How is Eclipse F4 applied?

Application is done manually, by machine, by drone or by helicopter, on a clean and dry roof. The dilution rate and the sprayed volume are adjusted to the chosen method, the greenhouse type and the climate.

How is Eclipse F4 cleaned off?

Eclipse F4 wears off gradually over the season, depending on weather conditions. It therefore needs no cleaning at the end of the season. Should removal become urgent, Eclipse F4 is easily cleaned off with Eclipse Net.
