PAINT AND COATINGS MANUFACTURING: TESTING EQUIPMENT
to customisable rooms or multiple installed luminaires.
MP: We also offer a range of portable spectrophotometers
with customisable colour specifications including texture,
and multi-angle devices with sparkle and graininess
measurements. They come in various geometries to
accurately measure any type of colour. In addition, we have
a 45/0 instrument that not only quantifies colour and gloss
but includes surface texture measurements. These portable
spectrophotometers help accelerate time to market as they
easily identify colours and can send measurements to a lab or
distribution point for the creation of custom colours. We also
have software packages that enhance search capabilities and
generate formulas for specialised colour requirements.
GS: Maintaining and updating pigment and colourant
databases is crucial for custom colour formulations as it allows
for quick adjustment changes in supply. We can provide third
party lab support to create samples and supply updated files
that work with our spectrophotometers to ensure that your
lab capabilities stay current and improved.
James Fusco (JF): Coating thickness uniformity across a
surface is key for performance and appearance. Measuring
film thickness helps prevent issues like under-coating, which
is insufficient coverage for protection, or over-coating which
wastes materials and causes potential defects. Gardco carries
a variety of coating thickness gauges such as eddy current,
magnetic, and ultrasonic thickness gauges that provide
real-time measurements. Our wet film thickness gauge is
another example of a quality control tool that is important for
manufacturers to determine the correct wet film thickness
for proper application.
CFCM: Do environmental factors have an effect on
achieving consistent colour in different production
batches?
JF: In field production, factors like temperature, humidity,
substrate variations, and application techniques can cause
colour discrepancies. Implement a robust quality control
process that includes regular testing of paint batches
and adhere to standard operating procedures for mixing,
application, and drying conditions to minimise variations. A
spectrophotometer can also be used to measure colour and
adjust the formulation accordingly. And maintain the optimal
temperature and humidity levels within the recommended
range for application and drying.
CFCM: How can processors optimise their Titanium
Dioxide (Ti02) usage?
