Product Description
DOWSIL FOOD GRADE 733 & HIGH TEMPERATURE SILICON SEALANT
DOWSIL FOOD GRADE & HIGH TEMPERATURE SILICON SEALANT 733
Package contains : 1 Pcs. , 300Ml Silicone Sealant
Marine Equipment silicone sealant with tensile strength of 2.3 MPa
Good resistance to weathering, vibration, moisture, ozone and extreme temperatures
Sustained flexibility at temperatures from -57 to 177C (-70 to 350F); intermittent to 204C (400F)
One-part silicone rubber that is easy to apply as a non slumping paste
Exceptional Heat & Food Safety PerformanceThis silicone sealant exhibits outstanding temperature resistance, making it ideal for continuous use up to +260C and short-term spikes to +300C. It complies with FDA 21 CFR 177.2600 and NSF 51 certifications, ensuring safe contact with food and drink. Its high purity and reliability make it a preferred choice for kitchens, food equipment manufacture, and processing lines.
Fast, Flexible, and Durable ApplicationThe acetoxy, moisture-curing system provides a skin-over time of 1020 minutes and a full 24-hour cure for a 3mm bead at standard conditions. With ~450% elongation at break, it offers enduring flexibility and forms a strong, resilient seal that withstands mechanical movement, thermal cycling, and chemical exposure.
Versatile Compatibility & Easy ApplicationDOWSIL 733 bonds securely to glass, metal, ceramics, plastics, aluminum, and stainless steel. Its paste-like, non-sag texture allows for easy tooling and application on vertical or overhead surfaces. Its designed for industrial, OEM, food processing, and commercial applications where food-safe, high-temperature sealing is required.
FAQs of DOWSIL FOOD GRADE 733 & HIGH TEMPERATURE SILICON SEALANT:
Q: How should DOWSIL 733 Food Grade & High Temperature Silicone Sealant be applied for optimal results?
A: For best performance, apply the sealant to clean, dry surfaces. Ensure that the material thickness is within 112 mm as required. Tool the bead within 510 minutes, and allow it to skin over for 1020 minutes at 25C. Full cure (3mm thickness) takes up to 24 hours. Avoid use in aquariums or areas of continuous, prolonged submersion.
Q: What are the key benefits of using this food grade, high temperature silicone sealant?
A: DOWSIL 733 offers numerous benefits including food safety compliance (FDA, NSF 51), excellent resistance to heat, weathering, ozone, and UV. It remains flexible and durable over time, resists mold and mildew, and provides long-lasting adhesion, making it suitable for demanding food processing and industrial environments.
Q: Where can this silicone sealant be safely used?
A: This sealant is ideal for food processing equipment, commercial kitchens, OEM assembly, gaskets, bonding applications, and electrical insulation where food contact safety and high temperature resistance are essential. Do not use it for aquariums or in settings requiring prolonged immersion in liquids.
Q: What curing and storage conditions are recommended for this product?
A: Cure the sealant at ambient temperatures, with skin-over time in 1020 minutes and a tack-free finish within 1025 minutes at 23C, 50% RH. Full cure (3mm bead) requires up to 24 hours. Store unopened product below 32C (90F); shelf life is 12 months when stored properly.
Q: How does DOWSIL 733 perform under continuous and intermittent high temperatures?
A: DOWSIL 733 is engineered to maintain reliable sealing and flexibility during continuous exposure up to +260C, and can withstand brief periods up to +300C. It retains its mechanical and adhesive properties even after repeated heat cycling or extensive high-temperature use.
