Anti-Blooming Agent FD-A6

Permanent control of surface blooming and whitening in colored silicone rubber — the difference between parts that pass water-boil inspection and parts that come back as rejects.

Key Features

  • Permanent blooming control in colored compounds — not a temporary surface fix
  • Withstands water-boil testing without whitening
  • No effect on physical properties of the cured rubber
  • Non-toxic, odorless — suitable for food-contact and export products
  • Simple incorporation during normal compounding

Usage

  1. Add during compounding

    Add FD-A6 while mixing the compound — best results when added in the internal mixer (masterbatch) stage.

  2. Then add color

    Masterbatch / pigments are added after the anti-blooming agent is dispersed.

  3. Add the vulcanizing agent last

    Whether peroxide or platinum, the curing agent always goes in last.

Dosage guidance Light and medium colors: 0.3%. Black and deep colors: 0.5%. For transparent compounds, dosage differs — contact us for the recommendation for your specific compound.

What Is Blooming?

Blooming is the migration of low-molecular-weight components to the rubber surface over time — visible as a white frost or haze, often appearing days after production or after water-boil testing. It is one of the most common causes of silicone part rejections in kitchenware and baby products. FD-A6 addresses the root cause inside the compound, permanently.
