UV Maskants — Litemask™
UV-curable masking resins engineered for the temporary protection of aerospace components and electronic assemblies during aggressive surface finishing. Instant cure replaces slow-drying lacquers and tapes — withstands grit blasting, shot peening, acid plating, and anodizing, then peels cleanly without leaving residue.
Technical Specifications
Built for Surface Masking & Protection
Litemask™ formulations are specified across aerospace, electronics, and precision
manufacturing wherever instant-cure temporary masking and residue-free removal are critical.
Frequently Asked Questions
Common questions about Incure Litemask™ UV masking resins.
-
Litemask™ UV masking resins protect surfaces during grit blasting, sandblasting, chemical milling, acid etching, anodising, electroplating, and thermal spray coating. The cured film resists abrasive media, acidic baths, and elevated process temperatures, shielding designated surface areas from finishing operations.
-
Litemask™ conforms precisely to complex geometries, internal features, and curved surfaces that tape cannot reach. It cures instantly under UV light to form a continuous, pinhole-free mask with sharp edge definition. Unlike tape, it requires no cutting, fitting, or edge sealing — and peels off cleanly in one piece after the finishing process.
-
Litemask™ cures on demand under UV light in the 365–405 nm range — typical cure times are seconds to under one minute depending on UV intensity and film thickness. Instant cure eliminates the wait time of heat-cure or air-dry masking compounds and allows parts to proceed directly to the finishing operation.
-
Yes. Litemask™ is formulated to peel off in one clean strip without adhesive residue, tearing, or contamination of the finished surface. The peelable formulation maintains adhesion through the finishing process but releases cleanly on removal.
-
Litemask™ is available in multiple viscosity grades including thixotropic grades that stay in place on vertical surfaces without sagging before UV cure. Select the viscosity that matches your application method: brush, syringe, or automated dispensing.
-
Litemask™ UV masking resin is rated from −55°C to 105°C, providing protection through high-temperature finishing and coating processes. All grades resist grit blasting abrasion and acid bath chemicals typically encountered in aerospace and electronics surface finishing.
