Novel Isocyanate-Free Resins for 1- and 2K Protective Coatings

Product Number: 51219-193-SG

Author: Denis Heymans, Catherine Romanowska, Marcelo Herszenhaut

Publication Date: 2019

$20.00

Environmental, market, and cost pressures have led to the development of alternatives to conventional 2K polyurethane topcoats, including isocyanate-free binders. For example, 1- and 2K coating systems based on alkoxysilane chemistry find increased use in protective coatings.

Novel Raw Materials for Enhanced Polyurea Coatings Performance

Product Number: 41207-388-SG

Author: Courtney T. Thurau, Mark D. Conner

Publication Date: 2007

$20.00

A series of novel isocyanates based on low-free monomer TDI prepolymer technology has been developed for spray polyurea applications. Coatings formulated using these new raw materials have shown significantly higher tensile strength, modulus, abrasion resistance and tear strength compared to conventional MDI-based isocyanates.

Novel Self-Healing Chemistries for Elevated Tempurature Coating Applications

Product Number: 41209-519-SG

Author: Gerald O. Wilson, H. Magnus Andersson, Larry F. Evans, Scott R. White

Publication Date: 2009

$20.00

Self-healing polymers are a new class of smart materials, which have the capability to autonomically repair themselves after damage, without the need for detection or repair by manual intervention. To expand the scope of practical applications, new self-healing chemistries have been developed and evaluated for use in a wide variety of applications including coatings.

Novel Testing Methodology of TwoCoat and Three-Coat Systems for Steel Bridge Structures

Product Number: 51218-163-SG

Author: Elias Toubia

Publication Date: 2018

$20.00

Departments of Transportation currently use the conventional three-coat system as the predominant choice for the corrosion protection of steel bridge structures. Eliminating one step in the coating process could potentially save time and cost associated with lane closures and traffic control costs. This research paper evaluates several two-coat systems based on the zinc-rich primer and polysiloxane top coat technology.

Novel Waterborne Epoxy Resin Dispersion for High Performance Metal Primers and Concrete Floor Finishes

Product Number: 41210-573-SG

Author: Ming Tsang, Karl Sundberg

Publication Date: 2010

$20.00

A new and versatile waterborne solid epoxy resin dispersion with good flexibility and improved shear stability is presented. When this binder is used, high performance metal primers can be formulated without the use of anti-corrosion pigments. This is highly desirable since the toxicological effects of zinc phosphate and other zinc-based salts are causing environmental concerns.

ON THE TOPOGRAPHICAL AND PERFORMANCE EFFECTS OF REBLASTING A PREVIOUSLY PREPARED STEEL SUBSTRATE

Product Number: 51218-141-SG

Author: Carl Reed, Kat Coronado

Publication Date: 2018

$20.00

Of recent interest in the coatings world, is what to do when an abrasive blasted substrate does not meet the specified profile. For example, if the blast profile on a steel surface exceeds the specification limit, can the surface be reblasted with smaller abrasive blast media to reduce the profile into meeting the specification? At SSPC 2017 a paper was presented which addressed this scenario and found that the profile can be reduced using such reblasting process.

One Component Waterborne Resins for Direct-to-Metal Applications

Product Number: 41211-653-SG

Author: Raymond S. Stewart

Publication Date: 2011

$20.00

Direct-to-metal (DTM) is a coating characteristic required in many markets. In particular, the light industrial and do it yourself markets require simple easy to use one component formulations. The ever-changing market requirements compel the formulator to stay current on new resin developments to meet these challenges.

Paint System Performance Warranty

Product Number: 41215-905-SG

Author: Shameem A. Khan

Publication Date: 2015

$20.00

The study objective was to evaluate the cost effectiveness and feasibility of a paint system warranty from a coatings manufacturer for a specified coating to be applied over steel with minimum surface preparation (without removing completely the existing coating or tightly adhering rust) and to evaluate the coating performance at the conclusion of the warranty period.

Painting Water Storage Tanks In-Service: An update

Product Number: 41207-343-SG

Author: Tony Ippoliti

Publication Date: 2007

$20.00

Until a few years ago, water tanks were always drained before exterior surfaces were painted because surface moisture, if found below the water line, would lead to a coating failure. But a coating technology borrowed from the bridge and highway industry and put to a new use is bringing changes to the water tank marketplace. This presentation introduces the original project, includes the coating evaluation after 6 years, and concludes with additional tank examples.

Past Versus Present - Comparing Laboratory Performance of Vinyl Resin Coatings with Modern Epoxy-Polysiloxane Coating Systems

Product Number: 51217-076-SG

Author: David Tordonato, Bobbi Jo Merten, Allen Skaja

Publication Date: 2017

$20.00

Starting in the 1940’s, solution vinyl resin coatings were used extensively to protect steel structures in fluctuating immersion service from corrosion. However, these systems fell out of favor when more restrictive volatile organic compounds regulations were implemented in the 1990’s. Since then, traditional epoxy systems have become a workhorse in the protective coatings industry. Unfortunately, these materials tend to degrade in sunlight, and experience has revealed their service life to be suboptimal compared to legacy coatings systems such as vinyls

Penny Wise of Pound Foolish? Holding Primers for Solvent Free Epoxy Tank Lining

Product Number: 51219-207-SG

Author: Mike O'Donoghue, Vijay Datta, Margaret Pardy

Publication Date: 2019

$20.00

Coating practitioners are aware that single coat, thick film solvent-free epoxy linings have gained acceptance for their promise of productivity benefits which include a potential quick return to service for newly applied tank linings. From the vantage point of owners, applicators, inspectors and coating manufacturers this paper examines productivity and performance issues associated with a tandem approach of using a thin film solvent borne epoxy holding primer (especially over pitted steel) with a coat of solvent-free epoxy lining as opposed to using a single coat of a solvent-free lining applied direct to metal.

Performance Evaluation of One-Coat Systems on New Steel Bridges - Final Results

Product Number: 41211-622-SG

Author: Pradeep Kodumuri, Yuan Yao, Seung-Kyoung Lee

Publication Date: 2011

$20.00

In an effort to address cost issue associated with shop application of conventional 3-coat systems, FHWA completed a study to investigate the performance of eight one-coat systems and two control coatings for corrosion protection of highway bridges. Based on prior performance, a three coat system and a two coat system were selected as the control coating systems.
