Precision Control for Reliable Curing - A Catalyst for Every Curing Requirement
We offer a comprehensive selection of initiators tailored to different resin systems and processing conditions.
Our Initiator Portfolio
MEKP (Methyl Ethyl Ketone Peroxide):
- The most widely used organic peroxide initiator.
- Typically used in room-temperature curing of polyester and vinyl ester resins.
- Works well with cobalt naphthenate (CoNAP) promoters and DMA/DEA accelerators.
- Available in multiple isomer concentrations for enhanced cure control.
CHP (Cumene Hydro Peroxide):
- Preferred for high-reactivity vinyl ester resins.
- Provides lower exotherm temperatures and reduced shrinkage.
- Ideal for thick laminates made in a single pass without intermediate cure stops.
Our Initiator Portfolio Continued
BPO (Benzoyl Peroxide):
- Offered in powder, paste, or emulsion form (emulsions preferred for ease of use).
- Essential for sodium hypochlorite-resistant laminates.
- Provides a controlled cure with DMA accelerators, requiring precise ratio adjustments.
- Used extensively in corrosion-resistant applications.
BPO Cream Hardener:
- Specially formulated for polyester fillers and putties.
- Available in a white formulation to maintain filler color.
- Ensures fast, consistent hardening with minimal separation.
