WATER-BASED NON-SILICONE ADHESIVE TAPE FOR SKIS
A silicone-free adhesive composition for use as a tape on skis comprises at least one water-based acrylic polymer pressure sensitive adhesive.
1 . An adhesive formulation for use as a tape on skis, comprising:
a) 40-90 wt % of at least one water-based acrylic polymer pressure sensitive adhesive (“PSA”);
b) 5-20 wt % of at least one solvent-based acrylic polymer PSA;
c) 0.25-5 wt % silica;
d) 0.01-2 wt % silane; and,
e) 0.01-3 wt % of at least one isocyanate catalyst.
2 . The adhesive formulation of claim 1 , wherein the formulation
performs at temperatures from about 50-170° C. for at least 4 minutes at about 5-10 bars of pressure,
can bond to nylon in both smooth and embossed configurations,
functions on a polyester laminate,
has adhesion levels in a range of 4-6.2 Newtons/25 mm for smooth surfaces and in a range of 8-9 Newtons/25 mm for embossed surfaces, and
survives flame etching on the back side of a ski.
3 . A method for producing an adhesive tape for use on skis, comprising:
a) providing
40-90 wt % of at least one water-based acrylic polymer pressure sensitive adhesive (“PSA”),
5-20 wt % of at least one solvent-based acrylic polymer PSA,
0.25-5 wt % silica,
0.01-2 wt % silane, and,
0.01-3 wt % of at least one isocyanate catalyst;
b) mixing the components of step a) to produce an adhesive composition; and,
c) applying the adhesive to a film to produce an adhesive tape.
4 . The adhesive formulation of claim 1 , wherein the formulation is essentially silicone-free.
5 . The adhesive formulation of claim 1 , wherein the adhesive tape formed with the adhesive formulation is easily removable from and leaves no residue on a substrate to which it is applied.
6 . An adhesive tape, comprising:
a) 40-90 wt % of at least one water-based acrylic polymer pressure sensitive adhesive (“PSA”);
b) 5-20 wt % of at least one solvent-based acrylic polymer PSA;
c) 0.25-5 wt % silica;
d) 0.01-2 wt % silane; and,
e) 0.01-3 wt % of at least one isocyanate catalyst,
wherein the tape is manufactured as a roll that can be unwound by hand without a release liner.
7 . The adhesive tape of claim 6 , wherein the adhesive tape is essentially silicone-free.
8 . An adhesive formulation for use as a tape on skis, consisting essentially of:
a) 40-90 wt % of at least one water-based acrylic polymer pressure sensitive adhesive (“PSA”);
b) 5-20 wt % of at least one solvent-based acrylic polymer PSA;
c) 0.25-5 wt % silica;
d) 0.01-2 wt % silane; and,
e) 0.01-3 wt % of at least one isocyanate catalyst.
9 . The adhesive formulation of claim 8 , further comprising a film substrate to which the adhesive formulation is applied, thereby forming an adhesive tape.
10 . The adhesive formulation of claim 8 , wherein the adhesive tape
can removably adhere to a surface at temperatures from about 50-170° C. for at least 4 minutes at about 5-10 bars of pressure,
can bond to nylon in both smooth and embossed configurations, and,
has adhesion levels in a range of 4-6.2 Newtons/25 mm for smooth surfaces and in a range of 8-9 Newtons/25 mm for embossed surfaces.
