example 1
[0095] Example 1 is an example of two adhesives of the present invention (Inventive Adhesives A and B). Table 1 sets forth the ingredient list for the two adhesives.
[0096] Table 1
[0097]
[0098] Prepare the adhesive according to the following steps:
[0099] Adhesive A of the present invention
[0100] A suitably sized double arm paddle sigma mixer (Teledyne-Readco, Serial 106830) and bowl was cleaned and heated to 175°C. At time zero, with the paddle running at 60 rpm, 400 grams of ESCOREZ5400 and 50 grams of BNX-1010 were added, followed by the slow addition of KRATON and SOLPRENE. At the 15 minute point, all of the KRATON and SOLPRENE were added and the ingredients mixed until the mixture was uniform and homogenous. Scrape the sides of the bowl as necessary. At the 90 minute point, the mixture was homogeneous and homogeneous with no visible particles. The remaining ESCORE Z5400 was then slowly added with continued mixing. At the 100 minute point, slowly ...
example 2
[0105] Example 2 describes the T Peel test method used to determine the peel force of the adhesives of the present invention on cotton and microfiber fabrics.
[0106] materials and equipment :
[0107]Peel tester (Shimadzu Model AGS-X or Instrumentor's Slip / Peel tester, Model SP1013.) capable of a peel rate of 300 mm / min, with 55 mm wide jaws for receiving the full width of the fabric and capable of Load cells that measure forces up to 10N+ / -0.1N. A Peel tester is used to measure the peel force required to remove the adhesive from the fabric (ie, cotton or microfiber).
[0108] • Recording device for calculating the average peel force over the range (for Shimadzu peel testers, recording was performed with "Trapezium" software version 1.01 running under Windows). For Slip / Peel testers, record with the console provided on the Slip / Peel unit).
[0109] 4.5 lb PSTC Roller or PSTC Automatic Roll-Off (PR-1000 PowerRoll from Instrumentor (Strongsville, OH))

example 3
[0137] Example 3 describes the experimental procedure used to perform the DMA temperature rise test of the adhesive of the present invention. DMA measures stiffness and damping, these are reported as modulus and tan δ.
[0138] Materials and Equipment: Haake RheoStress 1 (RS1; Type 379-0001 from Thermo Scientific, Inc.) or similar oscillatory rheometer with temperature control settings from 120°C to -10°C and a 35 mm measuring gap with 1 mm Parallel plate geometry (Haake PP35Ti). The device is controlled by Haake RheoWin software version 4.3.
[0139] sample :
[0140] • About 10 g of a sample of the adhesive of the invention and a commercially available adhesive.
[0141] process :
[0142] • Set the temperature setting on the rheometer to 120°C.
[0143] • Determine the zero gap between the plates of the rheometer. The plates were kept in contact for several minutes to equilibrate the top plate temperature.
[0144] • The plates are then separated and the adhesive...
