Application outcome
Finished Products Made with This Resin Family
Typical finished products include clear decorative panels, display components, lighting lenses and cast ornaments. Final model selection depends on casting thickness, clarity, colour, exotherm control, cure schedule and finishing requirements.
Typical applications
- Small and medium transparent crystal crafts
- Decorative components and art castings
- Clear or semi-transparent sanitary-ware products
- Colour-controlled prototypes and cast components
Process fit
Applicable Process Scenarios
Recommended processes
- Transparent art casting
- Sanitary-ware casting after formulation confirmation
Selection priorities
- Positioned for transparent and semi-transparent cast products.
- Suitable for evaluation in crystal crafts, decorative castings, and selected sanitary ware components.
- The process should control color, entrapped air, cure exotherm, section thickness, and demolding cycle.
- Verified fields support initial selection; the curing system and final supply specifications are confirmed through sample trials and during inquiry or order processing.

Process workflow
Production Process
Transparent casting requires clean material handling, controlled mixing and degassing, a verified casting thickness and a validated cure schedule. The actual formulation and cure conditions must be confirmed before production.
- Mould and material preparation
- Controlled resin and cure-system mixing
- Degassing and careful casting
- Temperature-controlled curing
- Demoulding, finishing and optical inspection
