ALITA E4 Low-Color Accelerator
Category：Auxiliary MaterialsCode：ALITA E4 Accelerator
Overview
ALITA E4 is a high-performance accelerator formulated primarily from Cobalt Isooctanoate (Octoate) and styrene.
- Features: Exhibits high purity, excellent color stability (low color index), and high cobalt concentration.
- Applications: Widely utilized in various Glass Fiber Reinforced Plastic (FRP) products, gelcoats, artificial marble, and high-quality artistic castings.
- Advantages: Significantly improves curing quality. Due to its high reactivity, the required dosage is only half that of traditional "E-type" accelerators. It is currently one of the most ideal accelerators for room-temperature curing of unsaturated polyester resins.
