DOWSIL 736 Heat Resistant Sealant One-part silicone Applications The high temperature properties of this sealant make it ideally suited for:
DOWSIL 736 Heat Resistant Sealant Sealing and encapsulating heating elements in appliances
DOWSIL 736 Heat Resistant Sealant Aerospace gasketing Moving oven belts
DOWSIL 736 Heat Resistant Sealant Industrial ovens Bag filters on smoke stacks Other critical bonding, sealing, potting, encapsulating and protective coatings where parts must perform at high temperatures
Exceptional Temperature and Chemical ResistanceDOWSIL FOOD GRADE 736 is formulated to withstand extreme temperatures from -75C up to intermittent peaks of 315C, making it ideal for high-heat environments like ovens or industrial equipment. The silicone sealant also features moderate resistance to oils, water, and mild chemicals, ensuring durability where performance matters most.
Fast Curing and Flexible BondThis acetoxy-cure sealant provides a tack-free finish within approximately 14 minutes at room temperature and delivers a full cure in 24 hours for 6 mm thickness. Once cured, it remains flexible and secure, even under demanding conditions, and resists tearing with a 400% elongation at break.
Food Safe and FDA CompliantDOWSIL FOOD GRADE 736 adheres to FDA 21 CFR 177.2600 standards, making it safe for applications involving direct food contact. Its formulation is non-toxic once cured and ideally suited for sealing in food processing, packaging, and preparation areas.
FAQ's of DOWSIL FOOD GRADE 736 & HIGH TEMPERATURE SILICON SEALANT:
Q: How is DOWSIL FOOD GRADE 736 applied and what surfaces is it suitable for?
A: DOWSIL 736 is applied as a paste or sealant directly from its cartridge or tube. Recommended application thickness is between 3-6 mm. It is compatible with a wide range of substrates such as metal, glass, ceramics, fiberglass, and certain plastics. Ensure surfaces are clean and dry before application for optimal adhesion.
Q: What is the curing process and how long does it take to fully cure?
A: The sealant is acetoxy-cured and moisture-activated. It becomes tack-free in about 14 minutes at 25C. Full curing occurs within 24 hours for a 6 mm thick application. Thicker sections may require longer curing times; ensure adequate ventilation for best results.
Q: Where can this sealant be used in food processing or industrial environments?
A: DOWSIL FOOD GRADE 736 is engineered for sealing, bonding, and gasketing in areas exposed to food or high temperatures. It is widely used in food manufacturing plants, ovens, appliances, commercial kitchens, and environments where FDA compliance and heat resistance are essential.
Q: What benefits does this product offer for high temperature applications?
A: With continuous temperature resistance up to 260C and intermittent peaks to 315C, the sealant maintains its integrity and flexibility under thermal stress. It is especially suited for applications involving baking equipment, heating units, and high-heat industrial zones.
Q: How should the sealant be stored for maximum shelf life?
A: To preserve its 12-month shelf life, store the sealant in a tightly closed container in a cool, dry place below 30C (86F). Avoid exposure to moisture before use, as premature curing may occur.
Q: What safety and compliance standards does this sealant meet?
A: DOWSIL FOOD GRADE 736 complies with FDA 21 CFR 177.2600 for food contact and offers low VOC content. It is non-toxic after curing, provides high dielectric strength, and features a fast-curing, weather-resistant formula.
