Per Vendor: All of our glues dry clear. Cyanocrylates in general dry clear. However, they can turn white when curing in certain circumstances.
1) Using accelerator to cure the glue and spraying too much or too closely. Use a light mist and spray from 8-10 inches away.
2) When parts are moist or have some kind of alkaline substance on the surface- either circumstance will cause glue to cure white. Make sure the parts are dry and wipe down with alcohol or acetone any parts that are not clean.
3) Extremely high humidity and heat- that combination can cause the glue to turn white even if you do everything else right. In that case, you would need to do your bonding in a temperature and humidity controlled environment.
Barring the above conditions, our glue will dry clear.
