DOWSIL™ SE 5088 Low-Molecular-Siloxane-Controlled Neutral Silicone Sealant for Clean Rooms
DOWSIL™ SE 5088 is a one-part neutral alkoxy-cure RTV silicone sealant designed specifically for clean-room applications. It requires no mixing and cures at room temperature by exposure to atmospheric moisture. Dow recommends it for specific joint sealing and panel adhesion in clean rooms. A key feature of SE 5088 is its significantly reduced low-molecular cyclic siloxane content. Dow’s Japanese construction sealant selection guide identifies the product as a reduced-low-molecular-siloxane grade for semiconductor clean rooms and clean-room equipment. The material is non-flowing, making it suitable for vertical joints and localized sealing. Dow also highlights excellent weatherability and excellent unprimed adhesion. Typical values include a tack-free time of approximately 22 minutes at 50% RH, specific gravity of approximately 1.41, and elongation of approximately 534%.
