PPE Requirements for Polyurethanes Versus Non-Isocyanate Coatings: Is There Really a Difference?

by Leah K. Tipton, KTA-Tator, Inc.

The word isocyanate on a product label or safety data sheet might prompt the selection of an alternative coating and in some cases, facility owners and/or contractors have reportedly been reluctant to specify/use polyurethane coatings, based upon a belief that coatings containing isocyanates have more stringent personal protective equipment requirements than those for application of coatings that do not contain isocyanates. This article describes a study conducted to investigate this belief and determine if recommended PPE requirements differ between polyurethane and non-isocyanate containing coatings.

by Patrick Cassidy and Michael Kibler, Elzly Technology Corporation; and Cameron Miller, Paul Slebodnick and James Martin, U.S. Naval Research Laboratory

Feedback from waterfront personnel performing maintenance painting for the U.S. Navy has consistently questioned the Navy’s requirement for performing feathering. NAVSEA Standard Item (NSI) 009-32 defines feathering as tapering the edges of tightly adhering old paint at an approximate 30-degree angle into the newly prepared bare metal surface. This article describes a U.S. Naval Research Laboratory program designed to test the hypothesis that feathering does not affect repair coating system performance and discusses what this testing revealed.
