310-0651 Wire Dots, .256" (6.5 mm) Round
$49.00 pkg/450
Wire Dots are a wire tacking system consisting of pre-cut shapes of a thin, flexible polymer film coated on one side with a high-performance, electronics grade permanent pressure-sensitive adhesive. The result is a highly conformable, high-strength bond.
The adhesive on Wire Dots is commonly used for graphic attachment and membrane switch applications because it has excellent long-term quality, consistency, and durability. Wire Dots perform well after exposure to high humidity, UV, immersion in water, and hot/cold cycles.
Wire Dots will hold secure after exposure to numerous chemicals including cleaning solutions/sprays, saponifiers, mild acids, and alkalies, and will hold secure through a typical circuit board hot water wash.
