We make foam mats out of EVA, in China. It has a smooth slippery skin on it. Too slippery.
We need to glue little PU or Silicone or CR or SBR or TPE or rubber “dots” to the back, to prevent slipping.
We have vendors offering such dots, stuck to a liner with 9448A. I also know there is an 9448HL.
Will either of those stick well to EVA? Is there something better
Which adhesive will stick best to PU, Silicone, CR, SBR, TPE or rubber?
It does us no good to have the glue stick to the EVA, only to then not stick well to the dots, which would then fall of the glue.
If there is no glue great for both, could we stick the dots to a backing, with a great glue for that material, and on the other side of the backing, use a different glue great for EVA?
WE have 100K dots a year to stick on, and they need to stay on, so I need your best advice.
There is a lot to unpack here and until you have settled on your materials there is not too much advice we can give. The difference in rubber “dots” will change the type of adhesive that functions the best on EVA. A good starting point would be to check out 3M™ Adhesive Transfer Tape 9472LE, one of our 3M™ Low Surface Energy Acrylic Adhesive 300LSE products. This adheres well to EVA and low surface energy rubbers, although silicone would need a specific type of adhesive. Please let me know if you have any more questions.
