Technical Product Information

DOWSIL™ 732 Adhesive Sealant White 310 ML

Product Overview

DOWSIL™ 732 Adhesive Sealant White is a 1-part, acetoxy room temperature vulcanizing (RTV) silicone adhesive and sealant designed for general-purpose industrial bonding and sealing. Formulated as a non-slump paste, it cures upon exposure to atmospheric moisture to form a tough, flexible white rubber layer. It provides excellent unprimed adhesion to glass, metals, ceramics, and various engineering substrates. The 310 ml cartridge packaging is ideal for easy manual or pneumatic dispensing.

Key Features and Benefits

• Multi-Purpose Industrial Bonding: Strong unprimed adhesion to metals, glass, ceramics, wood, and rigid plastics.
• Clean White Finish: Delivers a professional, aesthetic white finish for industrial and appliance assemblies.
• Non-Slump Paste: Can be applied easily on vertical and overhead joint surfaces without sagging.
• Broad Operating Temperature Range: Retains full performance from -60°C to +180°C (-76°F to +356°F) with short peaks up to +205°C.
• Weather and UV Stability: Outstanding resistance to UV, moisture, ozone, and outdoor weathering.
• FDA Compliance: Complies with FDA 21 CFR 177.2600 for indirect food contact applications.

Applications

• General purpose industrial bonding, sealing, and formed-in-place gasketting.
• Sealing glass joints, metal enclosures, and light-colored plastic panels.
• Environmental protection of electrical equipment boxes, ductwork, and outdoor housings.
• Food processing equipment and home appliance manufacturing requiring white sealant.

Usage Note: Ensure substrate surfaces are clean, dry, and free from oil or grease prior to application. As acetoxy cure releases acetic acid vapor during curing, test compatibility before applying on corrosion-sensitive metals (e.g., copper or brass). Easy to dispense using standard manual or pneumatic caulking guns.
