TRAILER CONSPICUTIY SKPT2RW
DURABILITY AND WARRANTY
10 year limited warranty
The KPT2RW Trailer Conspicuity Tape is a tough weather-and solvent resistant product designed for rugged outdoor use on the sides and rear of trucks and trailers. The Conspicuity Material is provided with the DOT-C2 certification mark as per NHTSA 49CFR571.108.
MATERIALS
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 0.008 inch thick and comes with an aggressive high-tack pressure sensitive adhesive.

Our KPT2RW Trailer Conspicuity Tape is available in white, red and alternating red and white striping. The colors conform to the requirements in Table 1 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° about its own axis after each reading.
REFLECTIVITY
Our Trailer Conspicuity Tape shall meet or exceed the minimum coefficient of retroreflection shown in Table 2. The sheeting shall be measured in accordance with ASTM E810. Rotation angles of 0 degree and 90 degrees are measured and averaged.

*=Meets or exc eds the requirements of ASTM D4956 Type V sheeting.
ADHESIVE
The adhesive is protected by a release liner that shall be removed by peeling, without soaking in water or other solvents. The adhesive produces a bond such that a one-inch wide strip shall support a 1-3/4 pound, (1.75), weight for five minutes without the strip peeling a distance of more than two inches when applied to a smooth aluminum panel as specified in the ASTM D4956 adhesion test.
IMPACT RESISTANCE
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 percent 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 (.625) rounded tip dropped from a 100 inch pound setting on a Gardner variable impact tester, IG-1120.
SHRINKAGE
A 9 inch by 9 inch specimen of the sheeting with liner is conditioned a minimum of one hour at 72 deg. F and 50 percent 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 inch, (0.03125), (in 10 minutes and 1/8 inch, (0.125), in 24 hours.
FLEXIBILITY
The sheeting is conditioned for 24 hours at 72 deg. F and 50 percent 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.
SOLVENT RESISTANCE
Our KPT2RW Trailer Conspicuity Tape meets the requirements of LS- 300C solvent resistance, section 3.6.7, when tested as specified in Table VI, test method 4.4.6.
SPECULAR GLOSS
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 degrees.
APPLICATION
The recommended application temperature to achieve best results is 65 deg. F (18 deg. C) or above.

-------- APPLICATION INSTRUCTIONS FOR
TRUCK CONSPICUITY SHEETING
Exceeds Standards
1. The conspicuity sheeting can be applied to flat surfaces. The surface must be free of rust, corrosion or loose paint. The sheeting can be applied at temperatures from 60 deg. F to 100 deg. F.
2. Before applying the sheeting, the surface must be free of dirt, grime and oils. It is best to assume that all surfaces are contaminated, and clean them before applying the sheeting.
Clean the surface with detergent
Rinse thoroughly and dry surface
Treat the surface with an alcohol wipe (isopropyl or methanol)
Make sure the surface is dry before application of the sheeting.
3. Peel back about 6" of the release liner and align the sheeting so it is parallel with the trailer. Apply the sheeting by pressing along the face using a non-scratch application device (plastic squeegee with a low-friction sleeve or hand roller). Start at the edge of the sheeting and work towards the release liner to ensure air bubbles don't get trapped under the sheeting.
