A Viable Alternative to Mineral Abrasive

Product Number: 51220-263-SG

Author: Joe McGreal

Publication Date: 2020

$20.00

Mineral abrasives such as glass bead and aluminum oxide have been traditionally used in the surface finishing industry. The general perception is that they offer acceptable cleaning at a low operating cost. Often dismissed is the potential of metallic alternatives that though seemingly higher in initial procurement cost, offer several differentiating advantages in terms of recyclability, consistency of finish, repeatable results and ultimately resulting in overall, reduced operating costs.

Bio Based Waterborne Floor Coatings with Enhanced Flow, Appearance, and Early Hardness Development

Product Number: 41215-900-SG

Author: Steve Hellems, John Willhite, Ramesh Subramanian

Publication Date: 2015

$20.00

The use of sustainable materials in the flooring market has gained widespread interest in recent years. Bio based raw materials contribute significantly to these efforts and are used to prepare environmentally friendly coatings. Castor oil-based emulsions are used as polyols in waterborne polyurethane coatings. These systems have outstanding chemical resistance and good durability. But they have inherent issues like very short pot life, poor appearance / flow properties, and delayed early hardness development.

Calibration, Verification, and Adjustment: Ensuring Accurate Inspection Measurements

Product Number: 51219-175-SG

Author: Markus Bieber

Publication Date: 2019

$20.00

Measuring physical parameters such as coating thickness, surface profile, and dew point is a common task for inspectors and applicators. However, those measurements are only as accurate as the instrument that performs them. Even high-quality electronic instruments can yield incorrect measurements.

Flexible Measurement Solutions for Industrial Painting and Inspection Applications

Product Number: 41214-833-SG

Author: Paul Lomax

Publication Date: 2014

$20.00

Structures are made of different substrates and materials. In order to protect these structures from the impact of corrosion, virtually everything is coated with some combination of paints, lacquers, epoxies, and thermoplastics. Inspecting structures requires multiple types of tests including measuring the thickness of a wide variety of protective coatings. This paper will discuss flexible measurement devices and how the utilization of various probes provides the best measurement results for specific applications.

Improvements to the Replica Tape Test Method (ASTM D4417C / NACE SP287 / ISO 8503-5)

Product Number: 51324-21157-SG

Author: Michael Beamish

Publication Date: 2024

$40.00

The Replica Tape method is a trusted method used by inspectors worldwide for decades to measure surface profile height. Previous studies have shown the method to be highly precise and accurate, but an intricate burnishing technique and requirement to average two different grades of replica tape in some measurement ranges made the method challenging for some users. This paper details two proposed changes to the method: an updated burnishing tool and linearized measurement scale to eliminate the need for averaging. A study was conducted to determine the accuracy and precision of this updated method, involving measurements performed by 15 users of varied experience on a range of test panels blasted with varying of media and profile heights.

New Developments in Surface Profile Measurement for Blast Cleaned Surfaces

Product Number: 41213-746-SG

Author: J F Fletcher

Publication Date: 2013

$20.00

When protective coatings are to be applied to structures, it is important that the surface is clean and dry if premature failure of the coating is to be prevented and the full coating service life achieved. In many situations for both new build and repair of structures, blast cleaning of the surface is required to remove contamination and to create an anchor pattern to enhance the adhesion of the coating system to the substrate.

PROFILE OR ROUGHNESS, WHICH IS IT?

Product Number: 51218-090-SG

Author: David Barnes

Publication Date: 2018

$20.00

This paper looks at the measurement of both profile and roughness on metal surfaces prepared specifically to receive a coating system in order to protect it from corrosion. The difference between roughness and profile is discussed, whether one is more relevant than the other, and the merits of the different measurement methods for both parameters.

Surface Roughness Profile and its effect on Coating Adhesion and Corrosion Protection

Product Number: 51220-238-SG

Author: S. G. Croll

Publication Date: 2020

$20.00

Modern design, manufacturing and field-testing specifications include surface profile and adhesion testing on the assumption that they are linked to long term corrosion prevention. There are a number of careful studies, dating back decades, that find no link between measurements of adhesion and (undercutting) corrosion performance, but other studies do, and the concept remains intuitively appealing and widely assumed.

The Effect of Peak Count or Surface Roughness on Coating Performance

Product Number: 41206-284-SG

Author: Hugh J. Roper, Raymond E.F. Weaver, Joseph H. Brandon

Publication Date: 2006

$20.00

Putting a long-held assumption about surface profile to the test, the authors show this: profile peak count can be measured, it can be controlled, and it does make a difference in coating performance.
