Preliminary Investigation into the Exterior use of Elastomeric Acrylic Coatings for Naval Facilities
Abstract
This effort is in response to a request by the Naval Facilities Engineering Command (Atlantic Division) to conduct a preliminary investigation into elastomeric acrylic coatings for exterior use by Naval facilities. Findings are as follows: (a) A water-based, direct-to-metal (DTM) acrylic primer followed by 20 mils dry of a water-based, elastomeric acrylic provided excellent protection to steel for over 2.75 years in a coastal marine environment, (b) elastomeric acrylics developed sound adhesion to 17 combined coated and uncoated substrates, (c) elastomeric acrylics generated low levels of residual cure stress (RCS) and, when used in maintenance painting, should transfer negligible stress to existing coatings, (d) elastomeric acrylics applied directly to steel resulted in significant flash rusting, however, the flash rusting neither affects adhesion nor bleeds into a topcoat when overcoated, (e) elastomeric acrylics exhibited acceptable performance when subjected to 1 week immersion in tap water and 3 weeks exposure in 95% relative humidity, (f) elastomeric acrylics displayed high performance when applied to Naval and commercial roofs, and (g) elastomeric acrylics may be suitable for use on a variety of exterior substrates located in diverse environments.
