Dow Corning DOWSIL™ RTV738-300ML Electrical Sealant, 300 mL, Cartridge, White, Slight, Paste

DOW one-part moisture cure adhesives such as DOWSIL™ 738 electrical sealant are generally cured at room temperature and in an environment of 30 to 80% relative humidity eliminating the need for curing ovens and the associated costs of energy and capital. >90% of full physical properties should be attained within 24 to 72 hr and varies according to product. Faster manufacturing throughput can be achieved since the adhesive and component can be handled in much shorter times of about 10 to 120 min, depending on the adhesive selected and the amount applied. These adhesives are not typically used in highly confined spaces or where a deep section cure is required as they generally cure from the exposed surface inward at a rate of 0.25 in per seven days. Cure progresses from the outer exposed surface and is dependent on the moisture in the air. Working time is generally a few minutes to an hour for these products until a surface skin begins to form. Mild heat below 60 deg C may be used to increase through put by accelerating the cure. DOW silicone adhesives retain their original physical and electrical properties over a broad range of operating conditions which enhance the reliability of and service life of PCB assemblies.
