I've been playing around with some Chinese UV adhesive- it seems to be an acrylic resin mixture (not much info in English, no MSDS etc.) . smells fruity like acrylic adhesives. Supposed to be for glass and plastic.
Anyway, it polymerizes pretty smartly when I hit it with light from a
10W 390-400nm- sorta UV LED, but the surface retains kind of an oily film on it, and the result is dull if the film is wiped off.Is this normal behavior for such resins?
Such info as I can find for the product refers to exposure to
220-260nm UV-C curing but a minute or so exposure to a germicidal 6W flourescent (should be ~253nm) seems to do nothing (still liquid).--sp
