  • the adhesive compositions on the coated fabric were fused in the oven at 190° C. for 1 minute.
  • coated fabric samples were then subjected to a 90° peel test.
  • Two test pieces of coated fabric size 3 ⁇ 20 cm were HF welded together with the coated sides facing each other, for an area of 2 ⁇ 15 cm.
  • test sample Each loose end of the test sample was clamped in a material test machine and peeled under an angle of 90 degrees at a speed of 100 mm/min. The average peel force was measured on 8 cm of the welded area, disregarding the start and ending of the test.
  • the force was extrapolated to N/5 cm bond width.
  • the peel test results are shown in FIG. 1 along with a coated sample that was made with just the prepared plastisol and no bonding agent.
  • the results show a good increase in peel strength with increasing amount of bonding agent.
  • the Vulcabond TP/TEHP 50/50 mixture results were comparable with the neat Vulcabond TP results.
  • the results of adhesive compositions that were allowed to sit for 24 hours at 30° C. showed little increase in peel strength, which is expected due to the limited pot life of the adhesive composition.
  • Example 3 was repeated except that DINP in the prepared plastisol was replaced with DOTP.
  • the 90° peel test results are shown in FIG. 2 along with a coated sample that was made with just the prepared plastisol and no bonding agent.
  • the results for DOTP adhesive compositions showed good peel strength increase with increasing amount of bonding agent.
  • the Vulcabond TP/TEHP 50/50 mixture results were in line or even better compared to the neat Vulcabond TP results. Also, there was no positive adhesion effect after storage of the adhesive composition for 24 hours at 30° C., as expected due to the limited pot life.
  • the results show a stable viscosity for both the DINP- and DOTP-based plastisols without bonding agent.
  • the adhesive compositions with Vulcabond TP showed higher initial viscosity compared to the samples with TP/TEHP.
  • the Vulcabond TP samples showed more viscosity increase within the first 5 hours than the samples with TP/TEHP.
  • TEHP provided a lower initial viscosity and better viscosity stability.
  • a bonding agent was prepared by vacuum distilling Desmodur RC (an aromatic isocyanurate trimer product from Bayer with 35 wt % of isocyanate in ethyl acetate) to remove the majority of the ethyl acetate.
  • the ethyl acetate was replaced with TEHP.
  • This solution was further diluted with TEHP to obtain a bonding agent containing 12.5 wt % of isocyanate.
