Anotation

This guide covers the selection and use of test methods for high-performance interior architectural wall coatings (HIPAC) designed for wall surfaces of steel, masonry (poured concrete, concrete block, or cinder block), and plaster or gypsum wallboard. HIPAC are tough, extra-durable organic coating systems applied as continuous (seamless) film and cure to a hard finish. HIPAC are not usually intended for ceilings and floors, and would not ordinarily be used in homes. The types of resin ordinarily used are epoxy-polyamide, two-package; polyester-epoxy, twopackage; and polyurethane, one-package or two-package. Practical requirements for HIPAC vary with substrate type and climate conditions. The tests for measuring the properties enumerated below are detailed. Liquid coating properties include: (1) skinning, (2) condition in container, (3) coarse particles and foreign matter, (4) density or weight per gallon, (5) fineness of dispersion, (6) odor, (7) flash point, (8) dilution stability, (9) volatile content, (10) free diisocyanate content, and (11) package stability. Coating application and film formation properties include: (1) brush, roller, and spray application properties, (2) rheological properties, (3) curing, (4) wet-film thickness, and (5) touch-up uniformity. Dry coating appearance includes: (1) color difference, (2) directional reference, (3) gloss, (4) hiding power, and (5) yellowness index. Dry coating properties include: (1) abrasion resistance, (2) adhesion, (3) impact resistance, (4) chemical resistance, (5) washability and cleansability, (6) mildew resistance, (7) perspiration resistance, (8) heat and cold resistance, (9) heat and humidity resistance, (10) fire hazards, and (11) dry-film thickness.
