Dymax SpeedMask UV Curing Temporary Masking

About Dymax SpeedMask UV Curing Temporary Masking

Dymax SpeedMask temporary masking resins are light-curable, single-component materials designed to protect selected areas of a component during surface processing. Instead of applying tapes, lacquers, waxes, or physical fixtures, SpeedMask is dispensed directly onto the part, where it forms a precise, conformal barrier over edges, holes, and complex geometries. Once cured, it creates a durable, chemically resistant mask that withstands aggressive processes including plating, anodising, grit blasting, thermal spray, and chemical etching.

SpeedMask is dimensionally stable, so it stays exactly where it is placed without running, even on vertical or intricate surfaces. It can be applied manually or through automated dispensing or spray systems, enabling accurate, repeatable coverage with a single layer. This allows you to mask fine features, sharp edges, and internal cavities that are difficult or time-consuming to protect using traditional methods. Exposure to the correct wavelength of UV/visible light converts the liquid gel into a solid polymer in seconds, on demand. There is no drying time, no ovens, and no waiting between coats. After processing, the mask can be removed cleanly by peeling or burn-off, leaving no residue and eliminating the need for post-process cleaning or rework.

Commercial impact and benefits
Masking steps that previously took hours or even days can be reduced to minutes. In one aerospace example, application time fell from four hours to just fourteen minutes, while maintaining near-zero tolerance accuracy. In another, a multi-coat lacquer process taking up to 72 hours was replaced with a single-step process completed in under 45 minutes. Beyond labour savings, this removes drying bottlenecks, reduces work-in-progress, cuts scrap and rework caused by leakage or inconsistency, and enables straightforward automation. The result is not just faster masking, but a cleaner, more predictable process that increases throughput without increasing risk.

Approvals
Dymax SpeedMask products are approved by major OEMs. Dymax 734-BT has Rolls Royce approval as metal spray maskant with the designation of OMat 2/241. Dymax 726-SC has Rolls Royce approval as metal spray maskant with designation of OMat 2/240.

Features & Benefits
