I am searching (though so far unsuccessfully) for an SMT adhesive that I can get in both white and black as opposed to the common red. My company does a lot of work with LED's and the red bonder has a tendency to affect the light output of LED's with transparent lenses.
I have currently only found red, pink and yellow as options. Loctite does have a black, but it is a cure-after reflow type, as opposed to the common cure-before type.
