Powder Coating Facilities

Getting the right coverage.

Overview

Powder coating is a type of coating that is applied as a dry powder to a surface. A powder coating does not require a solvent to keep the binder and filler parts in a liquid state before application. Powered coating our typically applied using an electrostatically method that is then cured under heat to create the coating over the materials surface.

Powder coating tends to create a hard finish that is tougher than conventional paint coatings. Primarily used for the coating of metals such as machinery component parts.

Building your coating booth

Powder spray painting booths are especially designed to suit the product and application equipment. Manual plants have different parameters for design as opposed to automatic plants. It most important to get the correct air to powder ratio within the prescribed limits to prevent the possibility of explosion. Insurance companies will recognize a properly designed plant.

BlastOne will design a booth which will be specific to your requirements, whether you are spraying to waste or reclaiming over-sprayed powder for reuse. We have many years of experience in engineering powder coating plant for ease of cleaning, quick color changes, reduced energy requirements. Our design for your application will take into consideration the specific brand and type of application equipment you prefer to use.

All of our designs will conform to government and local regulations.

Types of powder coatings

There are two main categories of powder coating: thermosets and thermoplastics. The thermosetting variety incorporates a cross-linker into the formulation. When the powder is baked, it reacts with other chemical groups in the powder to polymerize, improving the performance properties. The thermoplastic variety does not undergo any additional actions during the baking process, but rather only flows out into the final coating.

Production process:

1. The polymer granules are mixed with hardener, pigments and other powder ingredients in a mixer
2. The mixture is heated in an extruder
3. The extruded mixture is rolled flat, cooled and broken into small chips

The chips are milled and sieved to make a fine powder.
