Technical Product Information

DOWSIL™ 732 Multi-Purpose Sealant Clear 20 L

Product Overview

DOWSIL™ 732 Multi-Purpose Sealant Clear 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, clear rubber layer. It provides excellent unprimed adhesion to glass, metals, ceramics, and various engineering substrates. The 20 L pail packaging is ideal for automated industrial dispensing systems.

Key Features and Benefits

• Multi-Purpose Industrial Bonding: Strong unprimed adhesion to metals, glass, ceramics, wood, and rigid plastics.
• Clear Transparent Finish: Maintains high visual clarity without obscuring underlying joint details.
• 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 clear plastic panels.
• Environmental protection of electrical equipment boxes, ductwork, and outdoor housings.
• Food processing equipment and home appliance manufacturing requiring clear 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). The 20 L pail is designed for use with pneumatic follower-plate dispensing pumps.
