Flexible Prismatic Conspicuity Markings Series 963 are highly retroreflective flexible
microprismatic markings designed to mark the sides and rear of vehicles for enhanced visibility
and detection. The reflective marking consists of prismatic lenses that are formed in a transparent,
synthetic resin, reflectorized and backed with a pressure sensitive adhesive and paper liner.
Series 963 meets or exceed all FMVSS 108 requirements.
Features
• 2, 3, and 4 inch wide x 50 yard rolls
• High brightness
• Wide angularity
• 5 year warranty
Easy to apply
• Aggressive pressure sensitive adhesive
• Easy to remove liner
• Available in convenient rolls or kiss-cut pieces on a roll

Coefficient of
Retroreflection
The minimum coefficient of retroreflection values of these sheetings when new are given in Table
A in terms of candelas per lux per square meter. Measurements are made for samples applied to
an aluminum panel in accordance with ASTM E-810 “Standard Test Method for Coefficient of
Retroreflective Sheeting” and represent an average of values at 0 and 90 degree orientations.

Maintenance
Cleaning
Routine washing is recommended for maximum performance. The following cleaning methods are
recommended:
• Wash with sponge, cloth or soft brush using water and detergent.
• Standard high-pressure hand spray:
Maximum
pressure – 1200 PSI/80 bar.
Maximum
water/wash solution temperature – 140ºF/60ºC.
Minimum
of 12 inches/30cm distance between spray tips and markings.
Cleaning wand or spray tips to be at
no greater
angle than 45 degrees from perpendicular to the
marking’s surface.
Use Spray Tip – #1505 (15 deg spray angle, 05 capacity size)
• When using metal brighteners, follow manufacturer’s recommendations for dilution. Thoroughly
rinse from marking after soaking vehicle.
Storage
Routine washing is recommended for maximum performance. The following cleaning methods are
recommended:
• Store in a cool, dry area out of direct sunlight.
• Temperature 65-75ºF (18-24ºC)
• Humidity 30-50%
• Store rolls horizontally, in carton or in original packaging.
Shelf Life
Apply series 963 markings within two years of receipt of material.
Health and Safety
Information
General Performance
Considerations
Read all health hazard, precautionary, and first aid statements found in the Material Safety Data Sheet
and/or product label of chemicals prior to handling or use.
Series 963 markings will provide maximum durability when:
• 3M recommended procedures are followed.
• Markings are applied to vertical surfaces (within +20º).
Actual durability will be based on actual customer use conditions. Durability can be reduced if
recommended techniques are not followed, including:
• Improper application or surface preparation.
• Failure to cut markings around rivets, seams and body panels.
• Improper use of high pressure cleaning.
• Spillage of chemicals or solvents.
Warranty
3M warrants that 3M
™
Flexible Prismatic Conspicuity Markings Series 963 sold by 3M to be used
for markings in the United States and Canada will remain effective for the intended use and meet
the stated minimum values for coefficient of retroreflection for 5 years when applied on vertical
(+20º) surfaces. If the 3M reflective marking is applied in accordance with all 3M application and
fabrication procedures, including the exclusive use of 3M recommended application equipment; and if
the emblem or marking deteriorates due to natural causes, such as fading, cracking, peeling, lifting, or
discoloration; 3M’s sole responsibility and purchaser’s exclusive remedy shall be that 3M will provide
replacement of the 3M material.

Warranty
(continued)
Conditions
Such failures must be solely the result of design or manufacturing defects in the 3M reflective
markings and not of outside causes such as: improper handling, maintenance or installation; use of
application procedures not recommended by 3M; failure of substrate; exposure to chemicals, abrasion
and other mechanical damage from fasteners used to mount the marking; collisions, vandalism or
malicious mischief.
3M reserves the right to determine the method of replacement.
Replacement markings will carry the unexpired warranty of the markings they replace.
Claims made under this warranty will be honored only if 3M is notified of a failure within a
reasonable time, reasonable information requested by 3M is provided, and 3M is permitted to verify
the cause of the failure.
Limitation of Liability
