## Overview

Dow Corning 732 Black Multi-Purpose Sealant is a premium one-component silicone adhesive that cures at room temperature via an acetoxy system. It offers exceptional flexibility and durability across a wide temperature range (-60°C to 177°C), bonds to diverse surfaces, and provides excellent electrical insulation and weather resistance. Ideal for professional-grade sealing and bonding tasks, it cures to a tough rubbery finish within 24 hours under typical humidity, backed by a 900-day shelf life.

## Description

Dow Corning 732 Multi-Purpose Sealant is a one-component sealant/adhesive that cures at room temperature when exposed to the moisture in the air. When undergoing the acetoxy cure system, the product transforms from a non-sag paste to a tough and flexible rubber that adheres to many substrates. Dow Corning 732 Multi-Purpose Sealant is stable and flexible from -60°C to 177°C Dow Corning 732 Multi-Purpose Sealant has excellent dielectric properties. The product complies with MIL-A-46106 and FDA 177.2600. After 24 hours (at room temperature and 50% relative humidity) Dow Corning 732 Multi-Purpose Sealant will have a cure depth of about 3 mm. Limited atmospheric moisture and lower humidity levels will extend cure time. When stored at 32°C (90°F) the product's shelf life is 900 days from the date of its manufacture.

Review: Great Silicone adhesive !! Extremely weatherproof and relatively quick setup and cure ! - I used this for sealing electrical wires and hardwire installations. Extremely weatherproof and relatively quick setup and cure. Once cured it is a great insulator from both electrical voltage and current and weather. Have used this brand (Dow Corning) #732 for many years and has never failed me. It is not a free flowing sealant but is instead a thicker (like adhesive Caulking) style of adhesive.
Review: Excellent and easy to use. - Worked like a charm. Easy to use tube without having to deal with a gun or a mess. Idea of black was great to use when replacing a pad on my cooktop grate.
