When sealants are used in or around food-processing equipment, the requirements go beyond adhesion and flexibility.

The material may be exposed to cleaning agents, moisture, food products and temperature variations.

Therefore, regulatory and extractives testing becomes an important consideration.

MS-2000 Modified Hybrid Sealant has documented testing against FDA 21 CFR Part 175.300.

What Was Tested?

The MS-2000 sample was evaluated by TÜV SÜD PSB for:

Total Extractives Content

The test was conducted according to:

FDA 21 CFR Part 175.300 – Resinous and Polymeric Coatings

Three extraction conditions were evaluated.

1. Distilled Water

120°F for 24 hours

0.2 mg/in² — PASS

2. n-Heptane

70°F for 30 minutes

7.9 mg/in² — PASS

3. 8% Alcohol

120°F for 24 hours

0.4 mg/in² — PASS

The report compares these values with the specified <18 mg/in² requirement and records all three as Pass.

Why Extractives Testing Matters

When a material is used in a food-contact environment, substances potentially migrating from the material can be an important consideration.

FDA explains that food-contact substances are evaluated according to their intended use and conditions of use, including the potential for migration into food.

Therefore, simply describing a sealant as “food grade” is not sufficient.

The intended application and exposure conditions need to be considered.

Where Can MS-2000 Be Considered?

Subject to project-specific requirements, applications may include:

• Food-processing equipment interfaces
• Food production areas
• Equipment joints
• Panel interfaces
• Sealing around food-processing equipment
• Food-contact-adjacent joints
• Maintenance and refurbishment work

A Better Way to Specify Sealant

Instead of asking only:

“Is the sealant food grade?”

Project specifications should consider:

✔ Applicable FDA regulation

✔ Intended use

✔ Food type

✔ Temperature

✔ Contact conditions

✔ Cleaning regime

✔ Joint design

✔ Substrate compatibility

✔ Required testing documentation

This is where MS-2000’s documented FDA 21 CFR 175.300 testing becomes a valuable technical reference.

MS-2000 — Tested for What Matters

FDA 21 CFR 175.300 testing

Pass — Distilled Water extraction

Pass — n-Heptane extraction

Pass — 8% Alcohol extraction

Flexible joint performance

Excellent adhesion

Long-term durability

Conclusion

For food-processing and food-equipment applications, selecting a sealant based solely on general marketing claims is not enough.

MS-2000 offers something more useful: documented third-party testing against FDA 21 CFR Part 175.300 extractives requirements, together with established elastomeric joint-sealant performance.

For projects where food-contact compliance is important, MS-2000 can therefore be evaluated as part of the overall sealing system based on the specific intended use and conditions.
