Overview
ALITA 915N Sanitary Ware Structural Resin (Non-waxed Type)
Category：Hand Lay-up ResinCode：ALITA 915N
Features
ALITA 915N is a pre-accelerated, thixotropic, general-purpose unsaturated polyester resin featuring low viscosity and medium reactivity. This resin formulation contains no wax. Due to its exceptionally low viscosity, it provides outstanding wetting and impregnation capabilities with glass fibers, making it highly optimized for hand lay-up and spray-up processes.
- Low Exothermic Curve: Displays a low curing exotherm. Even during thick-section laminations for acrylic sanitary ware, it avoids overheating or causing thermal damage to the thin acrylic sheets.
- Cure Performance: Offers low shrinkage, light color, and minimal odor profiles upon final cure.
- High Filler Compatibility: Specially engineered for highly filled compound systems. Under high filler loading ratios, the compound maintains excellent flowability and workability, perfectly matching requirements of automated spray-up processes.
