Fundamentals of Making Good Decisions in Coatings Selection: Interpreting the Hidden Aspects of Accelerated Test Results

Fundamentals of Making Good Decisions in Coatings Selection: Interpreting the Hidden Aspects of Accelerated Test Results
Available for download

When selecting among decorative or functional/protective architectural coatings many factors need to be considered; one key aspect is how long the product will last (weather). A “ten year” warranty is neither a guarantee of total replacement cost nor that all “ten year” products are created equal.

When selecting among decorative or functional/protective architectural coatings many factors need to be considered; one key aspect is how long the product will last (weather). A “ten year” warranty is neither a guarantee of total replacement cost nor that all “ten year” products are created equal. Often marketing claims based on artificial or laboratory tests such as “passed 400 hours QUV” or “5 year equivalent accelerated weathering” are made, but what do these actually tell an architect, product specifier or contractor, and are they relevant? This paper will focus on identifying some of the key weathering durability tests and standards, some of their pros and cons, and what the results may really mean to end users.

Due to very severe conditions at offshore, conventional coatings do not work as they require multicoats to acquire high thickness and their curing times are rather high, giving chances for the contamination by severe environment (high RH and salt) in the intermediate layers. Thus, modern coatings which can give larger thickness in just one single coat and cure in a few minutes time are required for critical applications such as splash zone which is marred by continuous dry and wet spell.

The free flood areas of underwater vehicles pose a significant and expensive corrosion problem to operating forces. These areas undergo an alternating cycle of wetting and drying in a closely confined area that has regions of relatively stagnant seawater and other regions of high turbulence.  The corrosion induced damage requires constant upkeep by ship’s force and frequent expensive maintenance action by depot personnel to effect periodic full restoration.

Moisture Vapor Emission Rates of Concrete Floors – Can Moisture Meters be used Instead of Calcium Chloride?

Product Number: 41212-666-SG
Author: George Holz, Kevin Brown
Publication Date: 2012
$20.00

The moisture vapor emission rate (MVER) of concrete floors affects the selection of flooring materials for both new construction and remodel projects. The MVER is determined by exposing a 20” x 20” test area to calcium chloride for 60 to 72 hours.
