PLIOBOND® 5001 Pressure-Sensitive Adhesive
PLIOBOND® 5001 pressure sensitive adhesive is a permanent adhesive with clarity and strength properties that make it ideal for pressure sensitive tape, label stock and adhesive-backed foam. It has shown excellent adhesion to paper, polyurethane foam, polyethylene foam, foil and polyester film. PLIOBOND 5001 pressure sensitive adhesive demonstrates high tack, minimum cold flow, good aging characteristics, high peel strength and especially high shear strength. In test evaluations in film applications, PLIOBOND 5001 pressure sensitive adhesive samples were subjected to 1,500 gram loads, in contrast to the usual 500 gram load, on a 1/2 inch overlap and aged at room temperature. The results show that PLIOBOND 5001 pressure sensitive adhesive withstands extreme load conditions for long periods of time (see Table 2 – Typical Adhesion Properties on Dried Film).
PLIOBOND 5001 vs. Acrylic Adhesives
When compared to several acrylic adhesives, PLIOBOND 5001 pressure sensitive adhesive shows superior shear and peel adhesion, with and without aging, It is far superior to acrylic adhesives in initial shear and peel adhesion tests (see Table 3 – Initial Shear and Peel Adhesion Tests). After aging it still exhibits higher peel values than the acrylics. The testing showed one week’s aging caused a sharp increase in the shear value of the acrylic adhesives. This increase is due to the adhesive cross-linking during aging. The acrylics, however, were not cross-linked during the drying cycle and may require a much higher temperature to initiate this reaction in a short drying cycle. Aging has no effect on PLIOBOND 5001 pressure sensitive adhesive other than causing a slight increase in peel adhesion. Peel values of the acrylics changed very little during aging. After two weeks their peel values were virtually unchanged, although shear was further increased.
PLIOBOND 5001 pressure sensitive adhesive also demonstrates better tack properties than the acrylics tested. Rolling ball tack tests run on aged samples clearly indicate that the tack of acrylic pressure sensitive adhesives does not compare with that of PLIOBOND 5001 pressure sensitive adhesive. Thus, PLIOBOND 5001 pressure sensitive adhesive is easier to handle and more likely to make a satisfactory bond. With the exception of polyvinyl chloride substrates, PLIOBOND 5001 pressure sensitive adhesive was shown to be superior to the acrylic adhesives for pressure sensitive applications.
Apply PLIOBOND® 5001 adhesive in a 1-2 mil thickness. PLIOBOND 5001 adhesive can be dried at room temperature or forced dried in a range of 100°F to 200°F (38°C to 93°C) for three to five minutes. When the PLIOBOND 5001 adhesive is dry, the adhesive film will remain tacky and can be bonded as desired.
When PLIOBOND® 5001 EPDM bonding adhesive is stored indoors, out of direct sunlight, and in the original, unopened container between 60°F and 80°F (16°C and 27°C), the shelf life is 6 months. Always rotate stock.
NOTE: PLIOBOND 5001 bonding adhesive should not be stored below 40°F (6°C). Once frozen, PLIOBOND 5001 bonding adhesive will not return to its original state.
