All Fouled Up’ - An Innovative Solution

Product Number: 41215-914-SG

Author: Kevin Morris

Publication Date: 2015

$20.00

Within the Wastewater Treatment process the growth of soft fouling materials (algae) create problems such as Total Suspended Solids issues, false BOD readings, clogged pumps, and reduced flow rates through the weirs of clarifiers. Furthermore, dead or dying algae can cause additional odor concerns. This phenomenon has cost municipalities and taxpayer’s untold amounts of money due to the required maintenance dollars spent to correct this problem.

Alphatic Polyurea Speification - The Development of SSPC Paint Specification 39

Product Number: 41205-183-SG

Author: Michael J. Masciale

Publication Date: 2005

$20.00

Recent polyurea resin technology advances have allowed for the development of value-added polyurea topcoats that are proving to be valuable alternatives for many polyurethane applications. The development of an SSPC specification for a weatherable polyurea topcoat is discussed for the purpose of providing a standard that will be acceptable throughout our industry.

Effectiveness of Epoxy and Moisture-Cure Polyurethane Coatings in Corrosion Mitigation of Embedded Rebar- an Experimental Study

Product Number: 51320-14405-SG

Author: Raghava Kumar Vanama, Balaji Ramakrishnan

Publication Date: 2020

$20.00

Chloride induced corrosion is the prime reason for the degradation of embedded rebar in reinforced concrete marine structures. The present study experimentally investigates the effectiveness of traditional two-component epoxy (EPX), and moisture-cure polyurethane coatings (MC) applied on the concrete surface in reducing the rate of chloride ingression compared to the conventional concrete with and without mineral admixtures like fly ash and GGBS. Coatings used in the present study are characterized by XRD, EDAX, FEG-SEM, water uptake, adhesion strength and contact angle tests. Rapid chloride migration tests (RCMT) were conducted on concrete with and without coatings. Resistivity offered against the chloride migration monitored during the RCMT test indicated that concrete with MC shown higher resistivity in the initial period and continued to decrease over the test duration at a faster rate, unlike EPX. The non-steady-state migration coefficients of the concrete cured for 28days and coated with MC and EPX coatings were found to be nearly 22% and 48% of that of concrete with SCM cured for 84days respectively. The study is further extended to monitor the corrosion of rebar embedded in coated concrete subjected to corrosion acceleration until the first crack appeared on an uncoated specimen. Variation in current flow, half-cell potentials recorded during the acceleration test and actual mass loss of embedded rebar estimated by gravimetric analysis are presented in this paper.

Polyurethanes in Seamless Polymer Flooring Systems

Product Number: 41209-520-SG

Author: Jing Zeng

Publication Date: 2009

$20.00

Polyurethane technologies have demonstrated their applications in a variety of seamless polymer flooring systems. Aliphatic polyurethanes are widely used as topcoats since they provide combinations of good color stability, gloss retention, abrasion resistance, chemical resistance, and weathering resistance. Recent development in polyaspartic chemistry offers more options in coating thickness, curing temperatures, and solids content.

Straining at a Gnat and Swallowing a Camel: Safety and Performance Issues with Two - Part Urethane Finish Coats

Product Number: 41206-272-SG

Author: Mike O’Donoghue, Ron Garrett, V.J. Datta

Publication Date: 2006

$20.00

An escalating amount of negative press on the tried-and-true polyurethane finish coats has arisen due to concerns with their free-isocyanate content. This paper explores performance aspects of polyurethanes with respect to their UV resistance properties, and safety issues associated with polyurethanes as a function of their precursor isocyanate molecules.
