Coating
Thickness Measurement
A variety
of recognized methods can be used to determine the thickness
of organic coatings. The method employed in a specific
situation is most often determined by the type of coating
and substrate, the thickness range of the coating, the
size and shape of the part, and economics... |

Multi-Layer
Measurement Set-up
on a PosiTector 200 B/Adv
When measuring a coating application for the first
time, it is best not to guess at the number of layers.
Instead, measure the total thickness first and examine
the graphical display. This article provides a two-step
process for adjusting
the instrument for multi-layer applications. |

Test
Methods for Coating Adhesion
For coatings to perform satisfactorily, they must adhere
to the substrates on which they are applied. A variety
of recognized methods can be used to determine how well
a coating is bonded to the substrate. |

Environmental Conditions
Optimal environmental conditions are essential for surface
preparation, application, and curing of coatings and
linings to maximize successful performance. This article
presents the five environmental conditions that should
be observed and measured and the effect each condition
has on a successful job. |
