SIHE 358 is a medium-viscosity transparent-casting unsaturated polyester resin for clear crafts, imitation-jade products, jewellery accessories, and small cast parts requiring controlled colour, air release, and surface quality.
Application outcome
Finished Products Made with This Resin Family
Real transparent cast samples and coloured clear panels illustrate the optical clarity, colour and shaping direction for SIHE 358. Final results depend on section thickness, colour, accelerator and initiator system, bubble control and the validated cure cycle.
Typical applications
- Transparent cast and imitation-jade products
- Cast jewellery accessories and craft items
- Transparent decorative parts and colour samples
- Small cast products after confirming section thickness and exotherm
Process fit
Applicable Process Scenarios
Recommended processes
- Transparent casting in a compatibility-tested mould
- Trial-based pigmenting and deaeration
- Casting at a validated section thickness to control exotherm
- Clarity, bubbles, shrinkage, surface, and demoulding evaluation
Selection priorities
- Transparent viscous liquid appearance from the exact-model source
- The 25 °C viscosity range is published with a test standard
- Acid value and non-volatile content are published with test standards
- Positioned for products requiring controlled clarity, colour, and surface quality
Process workflow
Production Process
The real pouring scene illustrates transferring the prepared transparent resin into a clean vessel or mould. Stable clarity with SIHE 358 requires validation of mixing ratio, low-shear mixing, deaeration, temperature, casting thickness and cure schedule. Adapted from the authorized exact-model 358 product page; cropped and stripped of all text, logos and identifying marks.
- Clean the mould, tools and casting area
- Meter the resin, colour and cure system to the trial formulation
- Mix gently and deaerate to reduce optical defects
- Pour at the validated thickness, temperature and working time
- Cure, demould and inspect clarity, colour and surface quality

The exact-model source publishes 25 °C and GB/T 7193-2008 for viscosity, GB/T 2895-2008 for acid value, and GB/T 7193-2008 for non-volatile content. It does not publish a gel formulation, accelerator/MEKP ratio, gel time, peak temperature, or full-cure schedule. The source lists cast-resin tensile, flexural, impact, heat-deflection, and Barcol values with test standards but does not disclose specimen formulation or cure regime. Heat-deflection temperature is not peak reaction temperature. All cast values remain internal and are not presented as website design specifications. Values on this page are typical material-screening data, not release specifications or batch-acceptance criteria. Only data with both an unambiguous model and applicable test conditions enter public comparison. A current dated TDS for the confirmed exact model and supply is provided through the Contact page during inquiry or order processing.
