Organic Peroxide · FRP Pultrusion
Three-component organic peroxide blend · Active oxygen 8.1-8.9%
L102 is a pre-blended organic peroxide curing agent designed for FRP pultrusion. It replaces traditional BPO + TBPB dual initiator systems with a single product — covering the full 80-140°C cure range with 17-30% less total usage.

Why pultrusion operators switch from dual-initiator systems to L102
Problem: BPO + TBPB requires two products — separate procurement, storage, and dosing. Mixing errors affect cure quality.
L102 solution: Single product, pre-blended at optimal ratios. Add 1-2% by resin weight — no accelerator, no second component.
Problem: BPO (benzoyl peroxide) is a Class 5.2 organic peroxide with significant explosion risk under heat, friction, or contamination.
L102 solution: Eliminates BPO from the formulation entirely. Safer handling, storage, and transport.
Problem: Single-initiator systems activate in a narrow temperature band, risking incomplete cure or requiring slower line speeds.
L102 solution: Three components activate at 72°C, 85-90°C, and 104-105°C — continuous initiation across the full mold temperature profile.
Problem: BPO + TBPB systems typically require 1.8 kg per 100 kg resin.
L102 solution: 1.5 kg per 100 kg resin achieves equivalent cure — 17% less initiator consumption, direct material cost reduction.

| Recommended Dosage | 1-2% (by resin weight) |
| Accelerator Required | No |
| Applicable Resin | Unsaturated polyester (UP) |
| Appearance | Colorless to pale yellow liquid |
| Shelf Life | 6-8 months (room temperature) |
| Packaging | 20 kg/drum |
| Component | CAS | 10h Half-life | Role |
|---|---|---|---|
| TBPO | 3006-82-4 | 72°C | Low-temp initiation |
| MIBKP | 28056-59-5 | 85-90°C | Mid-temp main cure |

Three activation stages ensure continuous free-radical generation across the full mold temperature profile. This is the core mechanism that enables single-component operation.

Common questions from pultrusion operators evaluating L102
A composite organic peroxide containing three initiators (TBPO, MIBKP, TBPB) pre-blended to cover 80-140°C cure range. Designed for FRP pultrusion as a single-component replacement for BPO + TBPB dual systems.
Yes. L102 is a direct replacement. Total usage drops from ~1.8 kg to ~1.5 kg per 100 kg resin. A step-by-step transition guide is available.
1-2% by resin weight, depending on mold temperature and line speed. No separate accelerator required.
Significantly lower than imported Trigonox C + Trigonox 21 combinations while maintaining equivalent cure performance in pultrusion applications. Contact us for a specific quote.
