Brush-On Polymer Seals Porosity in Aluminum Parts and Welds
AlumiSeal™ is a high-performance brush-on methacrylate compound specifically formulated for sealing porosity in aluminum parts under pressure. AlumiSeal's unique chemistry and low dynamic viscosity enable it to wick deeply into pores or seams and between close-fitting non-ferrous metal surfaces. Once AlumiSeal™ has cured, any excess material on the surface of the part is easily rinsed away with water, leaving the surface clean and ready for painting or other finishing. AlumiSeal™ does not alter critical surface dimensions.
AlumiSeal™ comes packaged in a 250ml kit with a shelf life of 12 months. Mixing the sealant's two components creates a VOC-free, low-viscosity, pale-blue liquid that can be easily applied by brush. Once mixed, AlumiSeal™ has an extended pot life of about one day, allowing multiple parts to be treated from the same kit. Drawing a vacuum improves penetration. Curing in the absence of air, AlumiSeal™ forms a pressure-tight seal that withstands continuous service temperatures of up to 180° C (356° F). In fact, parts treated with AlumiSeal™ have been tested leak-free at over 150 psi. Cured AlumiSeal™ has a typical hardness of 78 Shore D (ASTM D2240) and exhibits excellent resistance to a broad range of chemicals, including oils, glycol, chlorinated and fluorinated solvents, mild caustics, acid solutions, and water. AlumiSeal's unique chemistry allows fast, easy cleanup of parts, tools, and brushes with water - no detergents or solvents are required.
