ORALITE® V82 Conspicuity Material (Formerly a Reflexite Branded Product Cat # 18989) is a Type V microprismatic retroreflective sheeting. The sheeting is designed for rugged outdoor use on the sides and rear of trucks, trailers, school buses, farm equipment, automobiles and all types of mobile and industrial equipment.
The sheeting is composed of cube corner (microprism) retroreflective elements integrally bonded to a flexible, smooth-surfaced, tough and weather-resistant UV stabilized polymeric film. The prism surfaces are coated with a vacuum deposition of aluminum to provide a mirror surface to the prism facets. The resulting tape is not more than 0.006 inch thick and comes with an aggressive high-tack pressure sensitive adhesive.
ORALITE® V82 Conspicuity Material shall comply with the Type V requirements in ASTM D4956 and meet or exceed the minimum coefficient of retroreflection shown in Table 1. The sheeting shall be measured in accordance with ASTM E810. Rotation angles of 0 deg and 90 deg are measured and averaged.
ORALITE® V82 Conspicuity Material is available in white, yellow, orange, red, green and blue.
The colors conform to the requirements in Table 2 when tested in accordance with ASTM practices E308 and E1164 and standards E1347 and E1349. The measured values are the average of eight readings. The test sample is rotated 45 deg about its own axis after each reading.
The adhesive is protected by a release liner which shall be removed by peeling, without soaking in water or other solvents. The adhesive produces such a bond that a 1" (50 mm) strip shall support a 1 3/4 pound (0.79 kg) weight for 5 minutes without the strip peeling for a distance of more than 2" (50 mm) when applied to a smooth aluminum surface as specified in the ASTM D4956, section 7.5 adhesion test.
Following application to a smooth surface aluminum rectangle, 0.020 inch by 3 inch by 6 inch, the specimen is conditioned for 24 hours at 72 deg F and 50% relative humidity. The sheeting shall show no cracking when the face of the panel is subjected to an impact of a two pound weight with a 5/8 inch rounded tip dropped from a 100 inch pound setting on a Gardner variable impact tester, IG-1120.
The sheeting is conditioned for 24 hours at 72 deg F and 50% relative humidity. The release liner is removed and the sheeting is sufficiently flexible to show no cracking when bent in one second™s time around a 1/8-inch diameter mandrel with the adhesive contacting the mandrel.
ORALITE® V82 Conspicuity Material meets the requirements of LS-300C solvent resistance, section 3.6.7, when tested as specified in Table VI, test method 4.4.6.
The sheeting shall have a specular gloss of not less than 40 when tested in accordance with ASTM method D523 at an angle of 85 deg.
A 9" x 9" (229 mm x 229 mm) specimen of the sheeting with liner is conditioned a minimum of one hour at 73 deg +or - 3 deg F (23 deg +or- 2 deg C) and 50% relative humidity. The liner is then removed and the specimen is placed on a flat surface with the adhesive side up. Ten minutes after the liner is removed and again after 24 hours, the specimen is measured to determine the amount of dimensional change. The specimen will not shrink in any dimension more than 1/32" (0.8 mm) in 10 minutes and 1/8" (3.2 mm) in 24 hours.
Material must be applied when the air and surface temperature is 50 deg F-100 deg F. Use a clean towel and Isopropyl alcohol, or similar, to wipe the surface before application. If any air bubbles are trapped, use a pin to puncture the bubble and a squeegee to push the air towards the pin hole.
