A very inventive civilian employee of the Navy along with Ted Diamond, of Composition Materials, pioneered a new method of blasting with Walnut Shell Grit to selectively remove only the anti-fouling paint, leaving the valuable vinyl undercoating and the primer intact, resulting in a huge savings in material, labor, and out of service costs. The use […]

UV Masking Resins – Masking Solutions

Composition Materials’ UV Curable Masking Resins are available in standard Peelable and Burn-Off Grades. Custom grades can be formulated for applications that require unique specifications. Peelable grades offer excellent surface protection during surface finishing operations such as grit blasting, shot peening and polishing. Peelable grades are flexible resins with high adhesion frequently used to protect steel, aluminum, titanium, cobalt, nickel and other commonly used metals in the aerospace and medical implant manufacturing industries. Masking resins cure quickly when exposed to UV light and peel-off easily after a hot water soak. Burn-Off Grades provide excellent surface protection during aggressive turbine component
