•UV Curing Control: Mono-functional resins (e.g., MPUA4920) provide high tack; difunctional resins enhance cross-linking elasticity
•Low-Ash Casting: 0.03% ash content (vs conventional 0.1-0.5%) prevents casting defects and ensures complete mold burnout
•Epoxy Curing Cycle: High-temp curing (120°C/2h) decomposes residual monomers for medical/food-contact compliance
•Chemical Vulnerability: Epoxy resins swell in ketones/aromatics; reinforced formulations maintain integrity in corrosive environments
•UV Degradation: High-weathering epoxies maintain stability through aromatic backbone modification and UV absorbers
•Precision Limitations: ≤5mm casting thickness requires nano-silica additives to control viscosity-induced flow restrictions
•Medical Certification: UV resins require USP Class VI and FDA 21CFR 177.2415 compliance for implant applications
•Flame Standards: Industrial epoxies must meet ASTM E84 Class B flame spread ratings for building codes
•Electrical Safety: Transformer encapsulation resins require IEC 60296 dielectric strength ≥30 kV/mm
