How to Address Defects in UV Resins on Difficult-to-Bond Substrates (Part 7)
Insufficient adhesion durability is a typical defect that can emerge in UV‑curable resins applied to difficult‑to‑adhere substrates over prolonged service. It manifests as compliance with initial adhesion test requirements, followed by a marked decline in adhesion after exposure to thermal cycling, humidity, or aging tests. This issue is particularly critical in applications such as automotive interiors and appliance panels, where long‑term performance is essential, directly impacting the service life and reliability of the coating system. Because UV‑curable resins for challenging substrates rely on adhesion promoters and modifying additives to achieve initial adhesion, their interfacial bonding mechanisms exhibit different stability under long‑term environmental conditions compared with conventional UV‑curable resins. To address this shortcoming, solutions can be pursued through both formulation design and process control.

How to Address Defects in UV Resins on Difficult-to-Bond Substrates (Part 6)
Surface defects are a typical challenge encountered when applying UV‑curable resins to difficult‑to‑adhere substrates, manifesting as irregularities such as craters, orange‑peel texture, or residual air bubbles on the coating surface. This issue is particularly critical in applications with stringent aesthetic requirements—such as automotive interiors and appliance panels—where it directly impacts both visual smoothness and protective performance. Because these substrates exhibit low surface energy, the wetting and spreading behavior of the coating differ from that on conventional substrates, leading to unique mechanisms and manifestations of surface defects. To address the three major types of surface defects—craters, orange peel, and residual air bubbles—solutions can be pursued through both formulation design and process optimization.
