*The typical values listed here are not to be construed as specifications. Gel times shown are typical but may be affected by catalysts, accelerators, polymerization inhibitor concentrations, resins, molds and shop temperatures. Gelation characteristics may change with different types of initiators and under very high humidity conditions. Pigments and/or fillers may retard or accelerate gelation. It is recommended that the manufacturer verify the gelling characteristics of a small amount of resin under actual operating conditions prior to use.
Product Description
AOC Vipel? K022 Series are styrene-soluble bisphenol A brominated epoxy vinyl ester resins.Vipel? K022 Series are ideally suited for hand lay-up, injection, twist and pultrusion molding processes that require excellent mechanical, chemical and thermal resistance.
The Vipel? K022-CN series contains antimony products.
major application
Vipel? K022 series are flame retardant resins for products subjected to particularly high static or dynamic loads such as chimneys and
Applications such as linings, non-combustible equipment, building boards and flooring materials.
Performance Characteristics
flame retardant
Some versions of Vipel? K022 do not require antimony trioxide to meet ASTM E 84 Class I flame spread requirements.
mechanical property
Vipel? K022 is suitable for products subjected to particularly high static or dynamic loads. The vinyl ester resin has excellent sustained heat resistance.
versatility
Extensive formulation capabilities make them suitable for many processes and optimize cost, performance.
Corrosion resistance
Vipel? K022 is highly resistant to a wide range of chemical environments. For information on corrosion resistance or for questions about the resin's suitability for any particular chemical environment, please refer to AOC's "Resin Corrosion Resistance Guide" and contact AOC.

Laminate construction: 2 layers of 2.0 oz per sq. ft. (600 g/m2) short cut glass fiber mat with 30% glass fiber content, laminate post cured at 100°C for 3 hours.
Process Operation Guide
- Maintain a hardener dosage level of between 1.01 TP3T and 2.51 TP3T of total resin weight to obtain fully cured strength;
- The temperature of the workshop should be maintained between 18℃ and 32℃, and the humidity of the workshop should be maintained between 40% and 90%. Constant shop conditions will result in constant gel time and help the manufacturer produce high quality products.
- The surface of manufactured products cured at room temperature in contact with air should be relatively non-stick. However, they may not be fully cured and therefore not as resistant to chemicals as fully cured products. If it is not intended to add further layers, 101 TP3T of 51 TP3T-containing paraffin (melting point:
- 46-48°C) of styrene solution to obtain a tack-free surface.
- Vipel? K022 series composite products already cured at room temperature are then cured at 70-100°C for two hours for optimum cure and performance.
- Room temperature curing promoted with cobalt salt solutions applies MEKP initiators with high dimer content to minimize bubble generation.
