DOWSIL 736 High-Temp Sealant Silicone Sealant Heating Elements & Industrial Ovens
Part 1: Basic Properties
DOWSIL™ 736 is a one-component, red, non-slump silicone sealant designed for extreme temperatures. It operates stably at continuous 260°C (500°F) and intermittent 315°C (600°F), curing into a flexible rubber solid suitable for vertical or overhead applications.
Part 2: Product Description
DOWSIL™ 736 cures via moisture, with a 10-minute skin time (25°C/50% RH) and full cure in 24 hours (3mm thickness). It offers high tensile strength (350 psi) and elongation (600%), complies with FDA 21CFR 177.2600 for food contact, and meets UL and MIL-A-46106A military standards.
Part 3: Special Properties
- Heat Resistance: Stable at 260°C long-term and 315°C short-term.
- Non-Sag: Zero slump for vertical applications.
- Certifications: NSF 51 food-grade and low VOC.
- Corrosion Note: Releases acetic acid during cure; avoid sensitive metals.
Part 4: Applications
- Industrial: Sealing oven conveyors, bag filters in chimneys.
- Electronics: Encapsulating heating elements (e.g., cartridges).
- Aerospace: Engine gaskets, high-temperature duct seals.
- Food Processing: FDA-compliant equipment sealing.
