AFCONA 3236 is an additive designed to provide slip and leveling, as well as good defoaming performance. It is an alkyl-modified polysiloxane that offers excellent slip and leveling properties. Unlike other organically modified polysiloxanes, AFCONA 3236 acts as a defoamer and does not stabilize foam in most systems, making it suitable for foam-sensitive applications such as floor coatings and high-build systems.

Features & Benefits

Product Features
  • AFCONA-3236 also acts as good defoamer and slip agent for heat-cured paints, especially coil coatings. It offers high temperature resistance - up to 280°C for 15 minutes.
  • AFCONA – 3236 is also used in wood coatings because of its good defoaming and slip performance. This product is not recommended in high gloss clear coats because it may cause slight in-can haziness.

AFCONA-3236 is recommended for use in the foam-sensitive systems listed below:

  1. Solvent-free epoxies
  2. High Solid or solvent-free polyurethanes
  3. Paints applied by curtain coater
  4. Paints applied by airless spray
  5. UV curing systems

Cure Method
Incorporation
AFCONA-3236 may be added at any stage of production process. However, high shear force is required to add it in the letdown stage due to the defoaming property. For easier incorporation, dilute to 10% in any solvent(s).
Addition and Dosage
AFCONA-3236 may be added at 0.05 - 0.50% based on total formulation. Under normal conditions, 0.05 - 0.2% based on total formulation is sufficient.
