Method for Measuring Energy Savings on Highly Reflective Coatings

Method for Measuring Energy Savings on Highly Reflective Coatings
Available for download

Real energy savings data for residential buildings is scarce and difficult to find. To address this concern, two identical houses were built in the outskirts of Monterrey, Mexico, where summer temperatures are usually very high (˜113°F). Energy consumptions using different waterproof coatings with different values of solar reflectance were evaluated.

Real energy savings data for residential buildings is scarce and difficult to find. To address this concern, two identical houses were built in the outskirts of Monterrey, Mexico, where summer temperatures are usually very high (˜113°F). Energy consumptions using different waterproof coatings with different values of solar reflectance were evaluated. The results show that a white, highly reflective, waterproof coating reduces the cooling load by 12% against a conventional white waterproof coating. Furthermore, the highly reflective coating reduced the cooling load by 44% against a red waterproof coating and by 51% against a black asphalt roof coating. This study shows that the use of highly reflective coatings is an effective technique to improve the energy efficiency on residential buildings.

Measurement of Internal Coating Stresses of MIL-PRF-23377 Top Coated with MIL-PRF-8528

Product Number: 41215-884-SG

Internal coatings stress (ICS) develops in coatings applied to a rigid substrates. During drying, volume changes due to solvent loss and/or cure induces stresses in the films. Differences in the thermal expansion coefficients of the coating and substrate also affect the ICS. ICS affects the interfacial adhesion and results in delamination once the stress exceeds the force of adhesion.

Methodology for Coated Infrastructure Inspection by Mobile Potentiostat

Product Number: 41215-912-SG

A test methodology is shown for field application of electrochemical impedance spectroscopy (EIS). The method utilizes low-cost, accessible materials to secure a temporary solution cell to the infrastructure’s coated surface. A laptop computer provides the power source and operating system for the mobile potentiostat during EIS data collection. This data provides a quantitative measure of the coating condition. The objective of this work is to incorporate EIS testing into standard coatings inspection to estimate remaining service life for the intact coating, which improves coatings maintenance planning for facility owners.

Development and Implementation of a Novel Method to Remove Inorganic Zinc Coating from Low Alloy Steel

Product Number: 41215-913-SG

Inorganic zinc (IOZ) silicate coating was previously applied to partially fabricated low alloy, 21/4 Cr-1MoV, high temperature, hydrogen, reactor vessels for long-term storage corrosion protection prior to final welding and post weld heat treatment (PWHT) at 690-720°C (1274-1328°F). The need for complete coating removal to mitigate the known embrittlement and weld cracking that can occur after welding and PWHT led to the development of a novel, environmentally friendly method to remove IOZ to trace levels below 1 ppm.
