Thermosetable Glass Cloth
Tape 365 and 3650
Application Method
Manual operation where the mat materials are cut and a 4” – 6” wide piece of
365 or 3650 is applied. Heat is applied either by hand or may be automated.
365 or 3650 is applied. Heat is applied either by hand or may be automated.
Key Application Requirements
Splicing material that has equal or greater tensile than the fiberglass mat. Low
profile. Must be able to make splice quickly (~ 30 - 90 seconds) Strength of
bond must equal or exceed tensile of fiberglass mat. Reliable splice at
temperatures up to 400ºF. Splice material is attached over entire surface of
glass mat so entire surface is coated. Material must be coatable with asphalt
mixture. For high slope shingles where rotary cutting is employed, it is best if
carbide blades are used on the tool vs. tooled steel, particularly in operations
with high through-put.

Benefits/Advantages To Customer
Superior reliability: Splices made with 3M

Thermosetable Glass Cloth Tapes
365 and 3650 have superior reliability compared to hot melt glue splices,
particularly in “bath” coating operations.

Lower Profile: 3M™ Thermosetable Glass Cloth Tape provides a thinner splice
than an overlapping glue splice, resulting in less change to finished shingle profile.
than an overlapping glue splice, resulting in less change to finished shingle profile.
Resists moisture: Butt splices made with 3M tape provide complete adhesive
coverage for the spliced web leaving no overlapping uncoated mat to absorb
moisture.

moisture.
Helps reduce maintenance: Use of tape eliminates the use of hot melt glue
guns, eliminating the time needed to clear plugged nozzles and routine
maintenance time for glue gun heads.
