Types of Powder PaintsPOPULAR AND PRACTICAL PAINTS
Powder coating is currently one of the most favored paint types, gaining popularity mainly due to its practical usage. It is constantly ready for use and will last you several years if stored correctly. This industrial coating is made from a mixture of resin, pigments, etc. Our paints can be used to treat surfaces of different materials in interiors and exteriors.

Powder coating process
JHow powder coating works:
Suspension and preparation of product
Suspension and preparation of product: The preparation of the product occurs before the powder coating process. Covering up parts of the product that are meant to be protected from the paint application. Suspension is either manual or with the help of forklifts up to the weight of 2500 kg.
Automatic rinse The first step is iron phosphating by spraying with jets in an automatic chamber. Phosphoric acid affects the metal and insoluble phosphates develop, they are bound in crystalline grids and have negative charges.
The last part of pretreatment is drying. The product is moved on an automatic lane into an oven with circulating air at a temperature of 170 ° C. The product surface has to be completely dry before powder coating.
The paint application occurs after drying in an automatic spray cabin. Eight fully automatic spray guns apply the paint to the product. At the beginning and end, there is also a workstation for pre-spray or final spray of products with a challenging shape.
The parts are routed to the hardening chamber oven after applying varnish. The powder melts, merges, and bakes (chemically reacts) into a compact hard layer. The chemical reaction causes polymer linking providing the surface durability against distortion. Fans circulate the heated air circulates. The temperature inside the hardening oven is in the range of about 140 - 220° C. The firing time is from about 10 - 30 minutes. The parts can be sent to assembly or further expedition immediately after cooling down. Once hardened, the surface can no longer melt or flow.
Packaging and expedition
The finished product is prepared for packaging according to our customer and ready for further dispatch.
