Acrylic Foam Tape GT7100 Series

GT7198 General Information : The Acrylic Foam Tape GT7100 Series, which is made by a special process, has a superior adhesion

performance and high flexibility. This tape is specially designed for exterior and interior parts attachments of

automobiles. GT7100 series provides equivalent adhesion properties to conventional Acrylic Foam Tape and

comparable initial adhesion performance at low ambient temperature with Hi-Tack Acrylic Foam Tape designed for

an improvement of low temperature workability.

Features : a) Excellent adhesive performance at low temperatures in comparison with those of the conventional Acrylic

Foam Tape.

b) Follows the shrinkage and elongation of the plastic part caused by the temperature change, and has good

stress relaxation properties which are very important for the automotive parts attachments.

c) Has a high final adhesion and peel strength.

d) Excels in a variety of weather, solvent and high temperature resistance.

e) Shows excellent workability and die cutting properties.

Painted panel : Conventional painted panel

Test methods : (1) Thickness : Measured by a dial thickness gauge (in accordance with JIS Z0237)

(2) 180ﾟpeel strength : Peel off the tape in 180ﾟ direction and measure the adhesion to the substrate with

a tensile test machine after the exposure in the following conditions.

a) Initial state : 23℃ x 20min.

b) Normal state : 23℃ x 24hrs.

c) At high temperature : b) at 80℃

d) Heat aging : b) 80℃ x 336hrs. b)

e) Warm water immersion: b) 40℃ water x 336hrs. b)

* Tape size : 25mm width, * Rolling pressure : 5kg roller one-way, * Peeling speed : 50mm/min.

(3) Shear strength : Measure the strength needed to shear after the exposure in the following conditions.

a),b),c) : as same as the conditions of the 180ﾟpeel strength

e) Warm water immersion : b) 40℃ water x 336hrs. b)

f) Gasoline immersion : b) gasoline x 1hr. b)

g) Wax-remover immersion: b) wax-remover x 1hr. b)

* Tape size : 25mm x 25mm, * Rolling pressure : 5kg roller one-way, * Tensile speed : 50mm/min.
