 Can-Tek Technical Support & Facilities
RESEARCH AND DEVELOPMENT
Our technical services department has a range of
specialised laboratory manufacturing and testing equipment
including a fully stocked laboratory and raw materials
library.
LABORATORY MANUFACTURE
We have mixing equipment suitable for a wide range of
paints, emulsions and surface treatment agents.
MIXING EQUIPMENT
We have the following paint, resin and emulsion mixing
equipment:
- Laboratory high speed disperser
Flame proof, variable speed from 250 ml sample to 20
litres capacity
- Factory small scale high speed disperser
Flame proof, variable speed from 20 litre to 1000 litre
capacity batches
- Laboratory bead mill
Suitable for glass, ceramic or steel beads
- Silverson ultra high speed emulsifier and
homogeniser
Suitable for emulsification of oil in water or fine
pigment dispersion
- Enclosed, dust free spray booth
- Panel preparation and finishing equipment
- Fully equipped test laboratory
- Extensive raw material library
- A range of raw materials stocked for various
projects
Slow speed mixer
Suitable for long, continuous mixing for procedures such
as resin dissolving.
Application equipment
Draw down bars are designed to apply a coating
efficiently in a dust free environment, evenly and at a
specific film thickness in order to evaluate dry time,
adhesion, gloss, appearance and resistance properties. The
coatings are applied and measured with both wheel and comb
wet film thickness gauges.
Opacity and spreading rate
A PFUND cryptometer is used to measure the wet opacity
and can calculate the expected spreading rate based on the
coverage. This test is done before a coating is aerosol
packed to ensure the opacity is adequate.
Aerosol compatibility
Specialised laboratory test canisters are used to observe
a product when packed with propellant inside an aerosol can.
Paint Tests offered
Paint evaluation
In order to obtain the best possible performance from
paint when aerosol packed we are able to offer the following
expert assessments of paint quality and suitability for
aerosol packing
- Spray, atomisation and flow properties
- Color and opacity
- Gloss level and appearance
- Pigment separation defects such as flocculation and
floatation
- Hardness, scratch, mar and chip resistance
- Adhesion over specified substrates
- Anticorrosive properties
- In-can stability where required
- Long term durability
- Chemical resistance properties
- Long term pigment suspension and re-incorporation
- Compatibility with propane, butane, Dimethyl Ether
and various propellants
