The Root of the Problem

If that doesn't work, Newell said, "There are non-yellowing additives that can be incorporated into an adhesive or coating to help prevent this occurrence."

Problem: Brittleness

Seen with UV coatings, brittleness results in cracking during scoring or poor scratch resistance—a symptom often confused with poor adhesion and cure. But really, Duncan said, "The issue is that the coating formulation is not matched to the UV lamp energy being used, and the coating is being cured beyond it's design criteria. This causes excessive crosslinking and results in brittleness."
