Proposed Performance Criteria for Encapsulant Coatings for Lead-Based Paint. 1.Abrasion Resistance

摘要

This study was conducted to develop preliminary performance criteria forencapsulants for lead-based paint. ASTM standards have been developed for encapsulants and data in the study may support revisions to these standards. Encapsulants are liquid-coating-based products installed over the surface of the lead-based paint to help to minimize the hazards of lead-based paint in housing. This report, the first in a series on the performance criteria, describes the cure time and abrasion resistance of 10 commercial encapsulants. Six nonreinforced and four reinforced encapsulants were selected. Six were acrylic-resin based; others were epoxy-, polyester-, and polyurethane-resin based, and one was inorganic-cement-based with an acrylic binder. Two household paints were included as controls.
