AFCONA - 3258 - Dar-Tech - Flow Promoter

Knowde Enhanced TDS

Identification & Functionality

Features & Benefits

CASE Ingredients Features: Improved Substrate Wetting
Product Features: AFCONA – 3258 is a specially modified polyacrylic polymer. It reduces drastically surface tension of organic coating systems. This, together with good compatibility in most solvent-based systems and with minimal foam stabilizing effect, makes it very effective as an anti-crater and flow control agent for all solvent based coating.

The leveling and anti-crater performance of AFCONA – 3258 can be further improve by combining with AFCONA silicone containing or fluorocarbon containing leveling agents. It will further improve the leveling, anti-crater and substrate wetting properties.

AFCONA-3258 is especially suitable for:

Stoving enamels based on alkyd, acrylic and polyester resins

Polyurethane coatings

Two-pack epoxy compounds

Thermoplastic system like NC, TPA and CAB

UV coating
Product Comparision: AFCONA - 3258 has been developed to replace fluorocarbon modified leveling agents, providing the same leveling and anti-crater performance. It is the 100% active version of AFCONA - 3758.
