Dymax Corp. offers its SpeedMask 750-SC ultraviolet/visible-light-curable masking resin featuring both temperature and chemical resistance. It is formulated to provide good surface protection during higher-temperature thermal spray coating, plasma spray, some HVOF processes and aggressive grit blasting. Additionally, this maskant can maintain adhesion during CNC grinding and machining. According to the company, resin cures on demand and saves hours of processing time when used as an alternative to labor-intensive manual taping or latex-based maskants with long cure cycles.

Formulated with the company’s See-Cure technology, the resin is purple in its uncured state, enabling automated vision systems and manual operations to confirm placement prior to cure.  As the product cures with sufficient light energy, its purple color transitions to pink and provides obvious visual confirmation that the maskant is fully cured.

The resin holds its shape after application via the company’s spray or dispense equipment, and its pink color eases confirmation of placement. It cures tack-free after proper cure with Dymax light-curing systems for quicker handling, can be removed through peeling or incineration, and leaves no residue after removal on nonporous surfaces. The company recommends this resin for surface protection on components manufactured from nickel alloys, titanium alloys and cobalt chrome.

The Systems View in Automotive Finishes: Essential, but Overlooked - The 38th William Blum Lecture

This article is a re-publication of the 38th William Blum Lecture, presented at the 84th AES Annual Convention in Detroit, Michigan on June 23, 1997.  This lecture reviews a number of works in automotive finishing R&D in which understanding of the overall system was absolutely essential to success, from classical nickel-chromium plating to work in vacuum/electroplated hybrids for plated plastics, electrogalvanized zinc and hard chromium in stamping dies.
