Sealant tapes for composites

  • sealant tapes for composites
  • Very high temperature sealant tapes

Ensure a perfect seal for all your vacuum processes

DIATEX sealing compounds ensure reliable, clean, and long-lasting vacuum sealing for all your composite processes: infusion, prepregs, autoclave, etc.

They ensure optimal adhesion between the vacuum bag and the mold, even under the most demanding conditions.

Our Different Types of Sealant tapes

Standard sealant tapes

Designed for use with vacuum-formed sheets, they ensure a peripheral seal between the sheet and the mold.

They ensure a perfect seal when installing the vacuum system, regardless of the type of substrate (composite, metal, wood, etc.).

Very high-temperature sealant tapes

Diatex also offers a range of specialty films:

  • Designed for cooking at temperatures up to 399°C
  • They come off easily without causing any mess or damaging the surface
  • Compatible with most vacuum-sealing films and molding tools
  • Ideal for autoclave and high-pressure processes

Frequently Asked Questions

What is composite sealant tapes used for?

Sealing compound is used to ensure that a vacuum bag forms an airtight seal over a mold. It prevents air from escaping during the vacuum or curing cycle, ensuring an effective and consistent vacuum.

What is the maximum operating temperature for Diatex sealant tapes ?

Depending on the product code, our sealant tapes can withstand temperatures ranging from 90°C to 399°C, making them suitable for use in all processes: infusion vacuum, autoclave, oven, and thermoplastics.

Are sealant tapes for composites compatible with all types of molds?

Yes. Diatex sealant tapes adhere perfectly to composite, metal, or wooden molds. They provide a strong bond and leave no residue when removed.

Can sealant tapes be reused?

No, they are designed for single-use to ensure a perfect seal during each production cycle. However, they can be removed cleanly and quickly, without requiring any additional cleaning.
