Webinar Sticks to Adhesion Testing

Tuesday, July 5, 2011

More items for Quality Control

The practical how-tos of pull-off adhesion testing will be the topic of a free upcoming webinar presented by JPCL and SSPC.

David Beamish, of DeFelsko Corp., will present the dos and don’ts of this critical test from 11 a.m. to noon EDT July 13.

David Beamish, of DeFelsko Corp., will cover the basics of testing per ASTM D4541.

Beamish will also explain the main differences between D4541, which primarily covers metal substrates, and D7234 (Standard Test Method for Pull-Off Adhesion Strength of Coatings on Concrete Using Portable Pull-Off Adhesion Testers), which was spun off in 2005 to address issues related to concrete.

Why Test Pull-Off Strength?

The pull-off strength of a coating is an important performance property that has been used in specifications. Variations in results obtained using different devices or different substrates with the same coating are possible. This test method serves as a means for uniformly preparing and testing coated surfaces, and evaluating and reporting the results.

The method is applicable to any portable apparatus meeting the basic requirements for determining the pull-off strength of a coating.

Registration, CEU Credits

The program is part of the JPCL/SSPC Webinar Education Series, which provides continuing education for SSPC recertifications and technology updates on important topics.

Participants may register free for the webinar here. SSPC is an accredited training provider for the Florida Board of Professional Engineers (FBPE), and Professional Engineers in Florida may submit SSPC Webinar Continuing Education Units to the board. To do so, applicants must download the FBPE CEU form and pass the Webinar Exam, which costs $25.

Free Coatings Webcasts Available

Numerous free webcasts are now available at www.paintsquare.com/webinars. Among the recent presentations:

“Protecting Steel Edges,” presented June 8, describes specific methods of obtaining sufficient coating thickness on steel edges and other irregular steel surfaces, where coatings tend to pull away during curing. The presenter was Bob Kogler, of Rampart LLC, former head of corrosion protection and coatings research at the Federal Highway Administration.

"Achieving Durability in Concrete Repairs," presented May 11, provides an introductory-level overview on selecting and using repair materials for structural concrete in a way that assures the durability of the repair.

BASF

The presenter was Peter Emmons, CEO of the Structural Group and past president of the International Concrete Repair Institute.

“Introduction to Common Coating Contract Evaluation,” presented April 13 by Skip Vernon of Coating and Lining Technologies Inc., provides a basic overview of clauses most common to coating contracts. The webinar identifies key provisions that may be missing from a contract and explains simple contract adjustments that may help avert disputes and litigation.

“Confined Space Safety,” presented March 16 by Allan DeLange of CL Coatings LLC, describes regulatory requirements and accepted industry practice in entering confined spaces and conducting surface preparation and coating work inside them.

OSHA

“Assuring Fall Protection When Working at Heights,” presented Feb. 24 by Bill Liang of KTA-Tator Inc., provides an overview of what employers should consider when implementing a safety program to control workplace fall hazards. The OSHA Construction Industry Fall Protection Standard requires that workers be protected from fall hazards—the leading cause of death in the workplace. In addition to compliance with OSHA, proper planning for and use of fall protection is critical to protect workers from this hazard.

Spider SafeWorks LLC

“Monitoring Environmental Conditions for Cleaning and Painting Operations, presented Feb. 23 by Bill Corbett of KTA-Tator Inc., addresses the procedures associated with monitoring prevailing conditions of air and surface temperatures, relative humidity, dew point temperature and wind speed before and during surface preparation and coating installation.
