Copper Neodecanoate 8% Cu CAS 50315-14-5 Process Promoter for Unsaturated Polyester Resin
Copper Neodecanoate 8% Cu CAS 50315‑14‑5 is liquid copper neodecanoate additive containing 8% copper metal content. It acts as an effective process promoter for unsaturated polyester resin systems. It regulates peroxide‑initiated curing reaction, suppresses unwanted pre‑gelation during storage and processing, optimizes exotherm profile and improves surface quality of finished UPR parts. It is widely applied for unsaturated polyester resin used in FRP composites, casting resin, hand lay‑up and mo
Product Overview
Copper Neodecanoate 8% Cu CAS 50315‑14‑5 belongs to neodecanoate‑series metal carboxylate functional additive for unsaturated polyester resin systems. It is not a primary initiator, but serves as a critical process promoter to modulate peroxide‑triggered curing behaviour. Unsaturated polyester resin tends to suffer premature gelation and unstable exothermic peak during storage or moulding process. This copper‑based additive adjusts catalytic activity, reduces early cross‑linking risk and contributes to better surface finish of cured composite parts. It exhibits excellent solubility in styrene monomer and various unsaturated polyester resins, maintains stable performance during resin storage and industrial batch production.
Key Features
‑ 8% standard copper content for stable and controllable promoting performance ‑ Neodecanoate structure with outstanding solubility in styrene and UPR matrix ‑ Effectively inhibits premature gelation during resin storage and processing ‑ Modulates curing exotherm curve, avoids excessive local heat accumulation ‑ Improves surface quality and reduces surface defects of cured UPR components ‑ Good compatibility with common peroxides and cobalt accelerators for UPR ‑ Suitable for hand lay‑up, casting and moulding compound process conditions ‑ Reliable batch‑to‑batch consistency for FRP and unsaturated polyester composite production
Technical Specifications
‑ Product Name: Copper Neodecanoate ‑ Copper Content: 8% Cu ‑ CAS No.: 50315‑14‑5 ‑ Appearance: Dark green‑brown transparent liquid ‑ Solubility: Soluble in styrene, unsaturated polyester resins and hydrocarbon solvents, insoluble in water ‑ Density: 0.91‑0.97 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥120℃ ‑ Moisture: ≤0.2%
Application Scenarios
‑ General‑purpose unsaturated polyester resin for FRP composite manufacturing ‑ UPR casting resin and hand lay‑up composite systems ‑ SMC / BMC moulding compound formulations ‑ Unsaturated polyester requiring improved storage stability and surface quality ‑ Composite formula cooperating with peroxide initiators and cobalt accelerators
Usage Recommendation
‑ Typical dosage: 0.04%‑0.25% calculated on total resin weight (as metal copper) ‑ Add and homogenize under low‑temperature mixing condition, avoid high‑temperature operation ‑ Do not premix directly with peroxide initiator to prevent dangerous reaction ‑ Works together with peroxide initiator and cobalt accelerator, cannot trigger curing alone ‑ Adjust dosage according to resin storage stability test, gel‑time and exotherm measurement ‑ Complete full‑set laboratory compatibility assessment before mass‑scale production
Package & Storage
‑ Standard package: 25kg / 200kg metal drum ‑ Store in cool, dry and well‑ventilated warehouse, keep away from heat source, direct sunlight and peroxide materials ‑ Tightly seal container after opening to prevent solvent volatilization and performance deterioration ‑ Shelf life: 12 months under proper storage conditions
Safety Notes
‑ Combustible liquid, keep away from all ignition sources. ‑ Avoid skin contact and eye splash. Wear chemical‑resistant gloves and safety goggles during handling. ‑ Avoid inhalation of vapor and mist, ensure effective local ventilation. ‑ Do not mix with peroxides. ‑ Refer to SDS for full guidance on handling, transportation and emergency disposal.
