Frequently Asked Questions
Glass, Metal, & Plastics Adhesives

Q: How long should I cure the adhesive?
It depends on application parameters. Cure time is influenced by variables including spectral output of the lamp, lamp intensity, distance of the lamp to the bond area, cure speed of the material and light transmission of substrates around the adhesive. Most applications require cure times of seconds under medium or high intensity UV/visible light.

Q: Do your adhesives expand or contract while curing?
DYMAX light curing materials shrink during cure. Shrinkage rate is dependent on the cure method and the formulation itself - DYMAX has materials that shrink less than 0.1% on cure. Linear shrinkage data is available on each PDS. Slow, low-intensity cures will reduce shrinkage rates of the light curing material.

Q: Do you have any adhesives suitable for dissimilar substrates?
Yes. DYMAX has a library of over 3,000 formulations. Most of the formulations were designed to bond unique and specific groups of substrates.A

Q: Do you have any adhesion promoters?
Yes, DYMAX does have primers available. Please contact BLAZE for help selecting the best primer for your application.

Q: In shadowed areas, can DYMAX adhesives cure if they are not directly exposed to light?
Yes. DYMAX Multi-Cure^® and Dual-Cure™ materials have secondary cure mechanisms to cure in applications were direct exposure to light is not possible for the entire application area. Multi-Cure products have a secondary heat cure, Dual-Cure products cure with moisture over time. Other products need light exposure to cure.

Q: How can I remove cured adhesive?
The most common methods of removing DYMAX light cure materials are chemical exposure or exposure to elevated temperatures.
