Dymax Speedmask 731 is a masking resin which cures in seconds on demand. Manufacturers can expect to save considerable amounts of time and labour costs in comparison to traditional taping, wax, lacquer systems or removable fixtures. It provides a quick, simple and reliable protection in the finishing of delicate or valuable parts and may also be used to seal cavity openings to prevent contamination. And its high visibility yellow colour helps with the application and removal QA process.
Typical applications cover aerospace, power generation, medical and precision metal fabrication where components such as turbine blades and orthopaedic joints can be precisely protected from treatments including grit blasting, acid stripping, plating, anodising, shot peening and plasma spraying.
The resin is readily applied by dispensing, spraying or jetting with manual or automated systems and has tenacious adhesion on nickel alloys, steel, stainless steel, aluminium, titanium cobalt and glass. It cures tack free for quick handling and is easily removed by water softening, peeling or incineration – it leaves no residue on non-porous surfaces. The material exhibits 500% elongation and very low shrinkage properties which make it a resilient post-cure maskant.
