Coating industry trends has driven increased use and interest to develop more efficient and durable thermal insulative coatings. The key areas for this expansion are to reduce corrosion under insulation, increase occupational safety and reduce energy loss. Key features of these water-based coatings are low thermal conductivity, high hydrophobicity and adhesion along with an emerging interest to have greater heat resistance and stability. This paper will introduce a new water-based silicone hybrid resin to accompany the two novel microporous composite granules; one with high thermal insulative efficiency and the other, a pure hydrophobic synthetic silica pearl shaped filler to optimize thermal insulation efficiency as well as offering mechanical stability and reduced cracking in these highly filled coatings. The new platform offers the formulator options to leverage all new technologies together or separately when a compatible binder is needed to increase thermal heat stability and flame-retardant performance. Coatings and formulating details will be highlighted with thermal degradation of binders, surface temperature comparison for “Safe Touch” coatings, thermal conductivity (Lambda - mW/mK), contact angle measurements along with fire retardance test and direct flame testing using various thermal insulation fillers.

New Two-Stage Corrosion Protection System Extends the Life of Concrete Structures

Product Number: 51319-13011-SG

Author: David Whitmore

Publication Date: 2019

Corrosion of reinforcing steel is a leading cause of concretedeterioration such as spalling cracking and delamination of reinforced concrete structures.This paper describes a new self-powered two stage anode system used to control corrosion in reinforced concrete structures. This two-stage system combines the high level performance of an impressed current cathodic protection system (ICCP) with the long-term maintenance-free capabilities of an alkali-activated galvanic cathodic prevention system (GCP).Impressed current and galvanic corrosion protection systems are beneficial in extending the service life ofchloride contaminated and damaged concrete structures. ICCP systems are typically powered by an outside DC power source such as a transformer/rectifier and can provide a lifetime of corrosion protection if suitably maintained. Galvanic systems use metals such as zinc that are more electronegative than steel in concrete. Galvanic systems are often used when simplicity is desired as there is no power supply involved and maintenance is minimal.This single-unit second generation hybrid system does not require complex wiring or an external DC power supply. Once installed the anode automatically provides an initial phase of high charge density that passivates active corrosion (Stage 1). The anode automatically switches to provide long-term maintenance-free galvanic protection (Stage 2) when the impressed current stage is complete.As a result this self-powered two-stage system provides a long-term maintenance-free corrosion protection alternative for reinforced concrete structures.

Corrosion’s destructive effects on critical steel infrastructure have costly economic and security
implications for the United States. According to a NACE International report from 2001, the annual
corrosion costs in the United States industrial sector were $47.9 billion per year, with the largest portion
stemming from the maintenance of critical utilities such as gas, water, electric, and telecommunications. Catastrophic failure due to corrosion jeopardizes the resilience of critical utilities, risking the interruption of service to millions and creates weak-points the nation’s homeland security.

New Understanding on Calcium Carbonate Scaling Kinetics

Product Number: 51319-12935-SG

Author: Qiwei Wang

Publication Date: 2019

$20.00

Calcium carbonate (CaCO3) is the predominate type of mineral scale formed in many industrial water processes including oil and gas production. Comprehensive and accurate knowledge on the CaCO3 scaling risk is critical for the effective scale management. Currently scale risk assessment is largely depends on thermodynamic simulation which predicts the saturation state under given conditions there are very limited experimental or field data on scaling kinetics. Previous works on temperature effect were investigated on nucleation and precipitation in bulk solutions which didn’t involve the CaCO3 adhesion and accumulation on existing surface. The pressure effect is considered in scaling tendency calculation but its potential impact on scaling kinetics is usually neglected.This paper presents the laboratory results of CaCO3 scaling kinetics at various temperatures (80-150°C) and pressures (500-5000 psia). Tests were conducted with a dynamic tube blocking apparatus which measures CaCO3 scale buildup by monitoring hydrostatic pressure differential (DP) across a capillary tubing and the time for scale formation was determined. Test waters were maintained at similar CaCO3 supersaturation state at different temperatures and pressures by adjusting bicarbonate concentration. Results show that under the test conditions scaling rate was accelerated by both temperature and pressure. CaCO3 scaling time was shortened approximately 2 times when pressure was increased from 500 psi to 5000 psi at the same temperature and similar supersaturation state. For examples scaling timeis decreased from ~65minutes to ~40minutes at 80°C and from ~40 minutes to < 20 minutes at 125°C with pressure changed from 500 psi to 5000 psi..This study provides new understanding on the mineral scaling kinetics by identifying the pressure dependence of CaCO3 scale formation process. Experimental results show that pressure other than its impact on solubility has additional kinetic effect on CaCO3 scaling rate. This kinetic effect should be included in the scaling risk assessment especially for the high pressure systems.

New Vinyl Coating System for the Marine Industry

Product Number: 41209-480-SG

Author: Daniel Harrison

Publication Date: 2009

$20.00

Vinyl coatings technology was pioneered shortly after World War II to control the corrosion on steel dam gates along the Mississippi River. Previously, oil-based technology had resulted in paints that performed well on atmospheric exposed areas of the dams but failed quickly in the areas immersed in water. By the mid-1950s, their proven durability had made vinyl coatings the industry standard for marine applications.

Fluoropolymer resins find widespread use as building blocks for ultra-weatherable coatings. Fluoroethylene vinyl ether (FEVE) resins were developed to overcome some of the problems associated with the application of standard fluoropolymer coatings. FEVE resins, which yield topcoats with expected lifetimes exceeding 60 years, can be cured at ambient temperatures for field application, or at elevated temperatures in the shop. In order to allow coating manufacturers to conform to government regulations on solvents, water-based FEVE resins were developed several years ago.

Cashew Nutshell Liquid (CNSL) is a non-edible, renewable biomaterial extracted from the honeycomb-like structure of the cashew nut. Its main component, cardanol, is produced by the decarboxylation of CNSL and it contains a highly hydrophobic aliphatic side chain. Cardanol is used in the synthesis of phenalkamines, which are widely used in marine, protective and industrial coatings applications. Historically, phenalkamines have been used in solvent systems, but recently, a new technology was developed that enables a very hydrophobic phenalkamine to be stably packaged in water.

Two coatings were developed for the intended purpose of maintaining steel sheet pile at the waterfront. The new splash zone coatings are free of VOC’s and HAP’s thereby providing a more environmentally friendly alternative to the standard coal tar epoxy system. The new coatings are also more abrasion and impact resistant and applied at more than twice the thickness of coal tar epoxy. All of these factors add up to an anticipated service life of 3 to 4 times that of coal tar epoxy leading to reduced life cycle costs.

Author: Donald Picard, Olivier Bellavance, Gabriel Cyr, Andréanne Potvin

Publication Date: 2022

$20.00

Pulsed Eddy Current (PEC) technology is a widely accepted inspection method now covered by several industry standards such as ISO⁽¹⁾ 20669, API⁽²⁾ RP 583, and the new ASME⁽³⁾ Section V (BPVC for Boiler and Pressure Vessel Code), article 21. PEC is a versatile inspection technology which provides an average remaining wall thickness through insulation and coatings. The technique can also be used to safely assess the minimum remaining ligament under corrosion scabs or blisters without surface preparation. PEC is resilient to liftoff variations and provides volumetric measurements of remaining material. It is capable of both detecting and assessing general corrosion on the outer surface of the pipes such as scabs and blisters, and detecting erosion or Flow Accelerated Corrosion (FAC) on the inner surface.
