Introduction
Complete Guide to Powder Coatings 1
Issue 1 - November 1999
There are two principal technologies that are the backbone
of the coatings industry:
􀀹 Liquid coating technology (wet), which has been
applied for more than two centuries
􀀹 Powder coating technology (dry), which has been
applied on an industrial scale for some 30 years.
The global average annual growth for powder coatings
has been approximately 7-9% over the last 10 years.
From country to country worldwide these figures have
varied considerably. This relatively high performance
has been achieved by autonomous growth on the one
side and by replacing liquid coatings on the other.
This guide is meant to provide background and
supporting information for those entrepreneurs who
have already elected to switch to powder coating
technology, or who are about to make that decision.
When the opportunity arises for coating technology
selection, there are a multitude of factors that need to be
considered and judged for their importance and weight
of impact. We discuss in this guide:
1) Applied materials
2) Application techniques
3) Health, safety and environmental implications
4) Quality achievements
5) Economic advantages.
Although thermoplastic resins were initially employed,
the thermosetting powders that were later developed
and applied have opened up much wider fields of use.
The accelerated application of thermosetting powder
coatings have therefore been a logical development in
light of the more stringent environmental requirements
and the demand for more commercially attractive
alternatives compared to conventional industrial liquid
coatings.
There are many advantages that make the choice of
applying thermosetting powder coatings so attractive to
the coating company:
1) Powder is immediately ready for use
2) Less powder wastage during the application
process
3) Reduced health hazard in case of exposure of
operators
4) Superior cured-film properties
5) Lower capital investment costs.
Today, many of the advantages of powder coatings are
no longer actively promoted as powder has secured its
place within the finishing industry. Advances in
powder technology have brought new opportunities,
such as:
1) Low film thickness powders
2) Substrates other than metal can be coated
3) Low curing temperatures can be achieved.
Today, the selection of a powder coating is dependent
upon:
1) Market demand
2) Industry requirements and standards
3) Price and finished cost.
