UV Dome Coatings — Cast-Max™

UV dome coatings are used for doming (creating a raised, lens-like protective layer over labels and displays), glob top encapsulation of bare-die ICs, thick-section casting, glass assembly, and lens casting. They produce a self-leveled, optically clear finish that protects underlying components from moisture, UV degradation, and mechanical impact.

Cast-Max™ is a single-part urethane acrylate optimised for deep-section casting, optical clarity, and minimal shrinkage — replacing traditional two-part casting resins that require long pot lives. Quad-Cure™ is a dual-cure formulation for applications where shadow areas exist. Both are self-leveling and cure under UV light in the 365–405 nm range.

No. Both Cast-Max™ and Quad-Cure™ are single-component formulations requiring no mixing, no pot-life management, and no catalyst. Simply dispense and cure under UV light — eliminating mixing errors, waste, and timed-application pressure associated with two-part casting resins.

Cast-Max™ cures to an optically clear, glass-like finish with no yellowing. It resists UV-induced yellowing over time, making it suitable for lens casting, display doming, and decorative coatings where appearance must be maintained over the product lifetime.

Cast-Max™ grades are rated from −55°C to 105°C to 125°C depending on the formulation. All grades resist moisture, thermal cycling, and common chemicals encountered in electronics and industrial environments.

UV dome coating grades range from approximately 4,100 to 8,600 cP — a flowable consistency that allows rapid cavity filling and efficient bubble release without requiring vibration or degassing. The self-leveling property ensures a smooth, uniform dome surface without manual spreading.
