What are the differences between powder and liquid shading agents?

Liquid shading agents and powder shading agents are both shading agents used to protect crops from excessive heat or UV radiation. The main difference between powder and liquid shading agents is their composition and of course their form. Since the 1970s, developments in the horticultural industry have increased rapidly. As greenhouses grew bigger and taller, gutters became longer and thinner, and spraying techniques became more sophisticated. With these developments, the demand for a different way of 'chalking' became louder and louder. It had to be easier, faster, safer and more accurate. From this demand liquid shading agents, or liquid shading paint, have arisen.

Composition and form

As described above, the main difference between powdered and liquid shading products is their composition and obviously their form: greenhouse shading powder is fixed and liquid greenhouse shading paint is fluid. This results in liquid shading paint not only being easier to mix and dose with water before applying, they are consequently much more weather resistant than shading powder agents are.

Applying shading agents

The latter therefore allows for differences in their application and deployment. Because liquid shading agents are more durable in rainy weather conditions, liquid greenhouse shading paint is mostly used in regions with rainy climates, such as Northern and Western Europe. Greenhouse shading powder is consequently deployed in regions with dry or drier climates, like the Mediterranean region. However, powder shading agents are also frequently used in rainy climates. When only a short period of shading is necessary, for example when a few days of tropical weather/temperatures/extreme temperatures are predicted greenhouse shading powder agents can also do the job. 

Removing the shading agents

One thing both powder and liquid shading agents have in common is their ease in removing. Whereas powder shading agents will slowly and completely wear off through elements of weather, liquid shading paint is just as easily removed by spraying with a shading agent remover, Removit. This is because liquid shading paint contains a patented binder for adhesion which needs to be dissolved.
With Removit it is possible to remove shading agents easily

Price of the shading agents

The final difference between both greenhouse shading agents is their price. Liquid greenhouse shading paint is more expensive than powder shading agents are. Is this an advantage of powder shading agents? Well, that depends on the usage, lifespan and applying method which you prefer.

What is a shading agent?
Some crops can't endure full solarization or high temperatures. Using a shading agent that reflects light can prevent heat peaks in summer, safeguarding the crops.
The differences between shading agents & coatings
Shading agents reduce the temperature inside the greenhouse by partially reflecting sunlight. Diffuse coatings are intended to let through as much light as possible. Discover more differences in this article.
