FDA Food Grade Silicone Sealant

x’traseal SN-501 and KB-51 deliver professional-grade sealing for food contact applications — certified, neutral-cure, and built for where hygiene cannot be compromised.

Not all sealants are suitable for food environments. If you’re sealing in a commercial kitchen, food processing facility, bakery, or cold room, you need a sealant that is FDA-certified for food contact, resistant to repeated cleaning, and non-toxic when cured. x’traseal SN-501 and KB-51 are engineered precisely for this purpose — and independently verified to comply with FDA Standards.

Meet x’traseal SN-501 & KB-51

Both products are part of x’traseal’s professional silicone sealant range, distributed exclusively in Singapore by GSK Advance Services. Together, they cover the full spectrum of food-safe sealing requirements — from joints and gaps to sanitary fixtures and surfaces requiring a strong, hygienic bond.

x’traseal SN-501

100% RTV Neutral Cure Silicone Sealant

A room-temperature-vulcanising (RTV), 100% silicone sealant with a neutral cure system. It does not release acetic acid or corrosive by-products during curing, making it safe for use on metal, glass, ceramic, and most building substrates in food environments.

x’traseal KB-51

Antifungal Kitchen & Bathroom Silicone Sealant

Formulated specifically for areas that require Anti-fungal requirements. KB-51 meets the material safety requirements for food-grade applications, offering excellent adhesion on stainless steel, ceramic, glass, and coated surfaces common in food processing and food service settings, and kitchen areas.

Why SN-501 or KB-51?

No Corrosion, No Odour During Cure

Some silicones like an Acetoxy-cure sealants release acetic acid (the smell of vinegar) as they cure. In food environments, this is unacceptable — it can taint nearby food, corrode stainless steel, and damage sensitive finishes. x’traseal SN-501 and KB-51’s neutral cure system releases no corrosive by-products, making it safe to apply without shutting down operations for extended periods.

High Temperature & Chemical Resistance

Cured silicone remains stable across a wide temperature range — from freezing cold room temperatures to the heat of commercial kitchen environments. It also resists the detergents, disinfectants, and alkaline cleaners commonly used in food facilities without degrading or losing adhesion.

Remains Flexible — Will Not Crack

Unlike epoxy or rigid sealants, x’traseal SN-501 and KB-51 silicone remains permanently flexible after curing. This means it can accommodate the natural thermal expansion and contraction of structures without cracking — extending the lifespan of the seal and reducing maintenance frequency.

Frequently Asked Questions

• Is x’traseal SN-501 safe for areas in direct food contact?

Yes. SN-501 has been tested and passed all three FDA 21 CFR 175.300 extractives tests — covering water, heptane (fatty/oily foods), and alcohol-based substances. Once fully cured, it is safe for use in food contact zones. Always allow the sealant to fully cure before food contact or resuming food operations.

• What is the difference between SN-501 and KB-51?

SN-501 is a 100% RTV neutral silicone sealant suited for general food-safe sealing applications including kitchens, cold rooms, and wet areas. KB-51 is specifically positioned as a food grade silicone sealant, designed for direct or indirect food contact environments. Both are distributed by GSK Advance Services. Contact us to confirm the best fit for your project specification.

• Can SN-501 be used on stainless steel?

Yes. As a neutral-cure silicone, SN-501 does not release acetic acid that would corrode stainless steel — unlike acetoxy-cure alternatives. It bonds reliably to stainless steel surfaces common in commercial kitchens, food processing equipment, and laboratory benching.

• Do my project need to have a bulk quantity to be eligible to purchase it?

We carry ex-stock so small quantity are welcome.

• Can I get the test report for SN-501 and KB-51 for tender submission?

Yes. Our complete test reports and data sheets are available upon request. Contact our team with your request and we will provide the relevant certification documents.
