Gloss ASTM

The standard test method utilizes a light source directed toward the sample surface at a specified incidence angle (e.g., 60°). The angle used depends on whether it is a high-or low-gloss surface. The quantity of reflected light is measured by a photosensitive receptor and correlates to the gloss value of the film. [Pg.112]

For the above polyol blend viscosity (Brookfield, ASTM D-2196) = 1500 mPa-S at 23° C. For the reaction mixture working (pot) life 20 min Gardner circular dry times [72°F, 54% relative humidity (RH)] surface dry = 1.0 h, hard dry = 2.0 h, mar free = 3.5 h. For the finished coating gloss (ASTM D-523) = 90+ at 60° impact (ASTM D-2794) = 60 in.-lb direct, 10 in.-lb reverse Tabor abrasion (ASTMD-4060,1000 g load, 1000cycles, CS-17 wheel) = 95.6 mg pendulum hardness = 180 s MEK double rubs (ASTM D4752-95, 50 double rubs) = softened. [Pg.253]

In flexible vinyl compounds, gloss is usually controlled with 1-3 phr of fine particle silica or talc, occasionally with ceramic microspheres. Measured gloss (ASTM D523) is, however, often lower in plasticized compounds if 2-5 percent acrylic impact modifier is used instead. This approach provides lower haze, generally better physical properties, and reduced equipment wear. The use of fine-pailicle fillers is preferable in cases where it is also operating to reduce plateout. [Pg.150]

Floor poHshes typically are evaluated for gloss, appHcation and leveling properties, discoloration, sHp resistance, scratch resistance, heel-mark resistance, scuff resistance, damp-mopping and detergent resistance, repairabiHty, lack of sediment, and removabiHty (3). RecoatabiHty and formula stabiHty are also important. A review of test methods is available (35). More than 20 ASTM test methods for floor poHshes exist. From the standpoint of product safety, sHp resistance is a particularly important variable and many test methods are available (39). [Pg.210]

Evaluations of furniture polish application properties, gloss, uniformity, film clarity, smear and mar resistance, film healing, buffability, cleaning, water spotting, gloss retention, and dust attraction are all described in ASTM D3751-79. Federal Specification P-P553B (1977) indudes some standard test methods for the evaluation of liquid furniture polishes. [Pg.209]

The gloss is measured before (ASTM D-1834) and after (ASTM D-2895) aging the sample for 1 and 7 days in an oven at 40°C (104°F). The specified aging conditions are intended to correlate with the conditions likely to occur in the handling and storage of waxed paper and paperboard. [Pg.310]
