Ultraclear™ 480 Series

A new series of water clear casting resins that are mercury free, have high physical properties, and are available in multiple gel times.

  • Exceptional clarity with refractive indices ranging from 1.502-1.585
  • Available in 10, 20 and 40 min. gel times.
  • High physicals such as: HDT, tensile strength, and impact resistance.

Ultraclear™ can be used in a wide variety of applications that require exceptional clarity; e.g., encapsulation, optical components, part overmolding, test models, and display pieces. The wide range of gel times makes Ultraclear™ suitable for small, average sized or larger castings.

NOTE: Hardness was tested after curing @ 80°C for 16 hours. For best properties, cure @ room temperature (21-23ºC) and postcure @ 60-80ºC for
4-12 hours. HDT and flexural strength increase with a postcure.
