Powder coating: storage problems and consequences

Coloring powders are not picky – they can be stored anywhere at any time of the year. However, mistakes in storage bring trouble, which must be corrected later. This will entail unforeseen costs, loss of time, unfulfilled orders. All this is very easy to avoid, you just need to follow simple rules in dealing with them, then you will always have an excellent result. “Lacover” wants your business to work like clockwork!

 

1. Check the humidity level in the room

Sometimes it happens that a lot of moisture gets into the room — especially in basements or semi-basements. Due to this, the powder settles into lumps that are invisible first glance The polymer film obtained from the wet loose mass will become uneven, and the thickenings in it will chip. Regularly check the composition for the presence of fungus and mix the paints before application.

2. Avoid exposure to direct sunlight

The sun’s rays heat up the powder paint — it will not fuse, but it can settle. Some types of powder coating materials are sensitive to ultraviolet, for example — epoxy and epoxy-polyester. While staying
long in the sun, their dye loses its original characteristics.

3. Maintain a stable temperature

LFMs are well stored at room temperature +5 – +25С — heat or cold outside this range can damage the friability. So, put the boxes in workshop near the polymerization furnace is a bad idea. If the material has been in a cold environment for a long time, it is better to place it in a warm environment before painting
room for 12 hours, and then put on a vibrating table.

4. Observe the storage terms

It is better not to exceed the expiration date specified by the manufacturer — after the expiration date, the properties of paints change, deviations in color, structure, dispersion, adhesion will appear. Expired paint can still be used by mixing it with fresh paint.

5. Pay attention to the integrity of the packaging

Damaged packaging lets in all kinds of contaminants, including dust. Impurities and debris can greatly affect the final result of painting, though it seems that the majority should burn out. But even in this case, a crater and unevenness will form on the spot, for example, particles of thread.
