Efficient Polyurethane Pipe Coatings for Harsh Conditions

Product Number: 41214-869-SG

Author: Andreas aus der Wieschen, Matthias Wintermantel, Todd Williams, Ahren Olsen

Publication Date: 2014

$20.00

Solvent-free two component polyurethane (2-K-PU) systems have been approved as suitable protective coatings systems since many years. Two component polyurethanes are favored within pipeline and tank constructions where high performance and durability have to be accomplished under harsh conditions (e.g., field application, high service temperatures, high salt load, wet soil conditions etc.).

Evaluation and Prediction of Protective Performance for Epoxy Systems and Epoxy/Polyurethane Systems in Wet and Dry Environments

Product Number: 41206-258-SG

Author: Chul-Hwan Lee, Chil-Seok Shin, Kwang-Ki Baek

Publication Date: 2006

$20.00

Current coating practice requires the thickness of anti-corrosion organic coatings to be over 250 for immersion parts of ships and offshore structures and the protective performance of these coatings has been evaluated by destructive and qualitative analysis. Recently, Electrochemical Impedance Spectroscopy (EIS) method has been employed, as an alternative, to evaluate corrosion resistance of organic coatings. This method is characterized as being nondestructive, reproducible, and quantitative in evaluating aging of organic coatings.

Field and Laboratory Experience with Polyurethane Pipe Linings

Product Number: 41214-863-SG

Author: Allen Skaja, David Tordonato, Bobbi Jo Merten

Publication Date: 2014

$20.00

The Bureau of Reclamation’s Materials Engineering Research Laboratory has been evaluating polyurethane pipe linings for severe immersion exposure, specifically for outlet works and penstock linings. Polyurethanes have several advantages over other coatings, such as application temperature range, faster cure times in cold temperatures, rapid return to service, coat large surface area rapidly, low viscosity (i.e., accommodates pumping over longer distances), and greater impact resistance.

Flame Retardant Polyurethane Corrosion Protective Coating

Product Number: 51322-17696-SG

Author: Mohammad Mizanur Rahman

Publication Date: 2022

$20.00

Metal and its structures corrosion is a natural process. The process started and accelerated in the presence of electrolytes [1, 2]. Thus, it's highly encouraged to stop this electrolyte passage. One of the ways to resist the passage of electrolytes is by making a barrier. The most popular method of such a barrier is an organic coating which mainly comes from polymer resin along with pigments, and additives. Different organic coatings are being used to make a barrier that can ultimately protect the metals and their structures. Epoxy, polyurethane (PU), and acrylate coatings are widely being used for this purpose.

Leak Mitigation of Dynamic Cracks in Concrete

Product Number: 41216-982-SG

Author: Charlie Lerman

Publication Date: 2016

$20.00

Concrete will crack – that is a fact. When cracks appear, they are dynamic or static, and structural or non-structural. If the crack is static, non-structural, and does not leak, epoxies are great to restore design strength. However, since concrete constantly shrinks, expands, and often leaks, the use of a flexible polyurethane resin to permanently seal active leaks is the optimum choice to create a leak-free environment.

Polyaspartic Coatings that Perform as Well as Polyurethane Coatings

Product Number: 41208-411-SG

Author: Beth Eng

Publication Date: 2008

$20.00

Polyaspartic coatings can offer excellent performance characteristics typically expected of SSPC Specification Number 36, Level 3, for Aliphatic Polyurethane Topcoats. In addition, polyaspartates will pass an industry standard for corrosion protection in medium corrosivity environments direct to metal. These features offer the typical industrial maintenance customer high performance for gloss and color retention, while reducing application time and costs.

Polyether Polyols: A Renewably Sourced And High Performance Ingredient For Coatings

Product Number: 41211-654-SG

Author: Hari B Sunkara, Ayumu Yokoyama, Patricia Sormani, Rajesh Saliya, Sheau-Hwa Ma

Publication Date: 2011

$20.00

There is a new family of 100% renewably sourced and high performance poly (trimethylene ether) polyols which is being manufactured in a sustainable process using an ingredient derived from agricultural feedstock. Owing to its unique structure, these polyether diols have many useful properties such as low viscosity, low melting point, slow crystallization rates, high flexibility, resistance to heat and acidic environments. These attributes are ideal for coating applications.
