Hi ThosePucks,
EVA and UHMW are both low surface energy (LSE) materials, so bonding to them can be tricky. Fortunately, 3M™ Hook and Loop Reclosable Fasteners come in a variety of adhesive backings. The following options have the strongest performance on LSE materials:
3M™ Hook Fastener SJ3530 / 3M™ Loop Fastener SJ3531 (our best hook and loop for LSE adhesion)
3M™ Hook Fastener SJ3526N / 3M™ Loop Fastener SJ3527N (higher temperature tolerance but slightly lower adhesion than SJ3530/SJ3531)
Please comment below if you have additional questions.
