Characteristic Performance

  • Excellent flame retardancy
  • chemical resistance
  • High Temperature Resistant Application Environments
  • Good mechanical properties

Typical Application

Atlac® 430YT-901 resin can be used in environments that are resistant to all types of acids, alkalis, bleaches and organic compounds. It is particularly suitable for chimneys and chimney liners in FRP piping systems. It is also suitable for equipment, building panels and flooring materials that require non-flammable conditions for handling air and hot gas mixtures. The
The resins are suitable for a variety of processes such as hand lay-up, injection, winding, RTM and pultrusion molding.
Atlac® 430YT-901 has a low viscosity and can be further enhanced with the addition of compatibilizers such as antimony trioxide without affecting processing performance.

Curing conditions
Curing system: 0.1g NL-53, 1.0g Butanox LPT per 100g resin. 24 hours room temperature cure and 24 hours post cure at 80°C. For HDT and Tg, add 0.1g NL-53 and 1.0g Butanox LPT per 100g resin. For HDT and Tg, cure at room temperature for 24 hours and post cure at 120°C for 2 hours.

Process Operation Guide

  • Atlac® 430YT-901 does not contain an accelerator and should be used with a cobalt-based accelerator.
  • Room temperature cured products must also be post-cured to achieve optimum physical and chemical properties. Before that, the products need to be cured at room temperature for 24 hours. Post-curing conditions are 80 to 100°C/3 to 6 hours (longer for thicker products). Post-curing is particularly important for parts intended for chemical resistance.
  • During the curing process, it is recommended to add 0.2% of wax with melting point 54-57 °C to the surface of the product, which is formulated as 10% of styrene solution when added.
