Product Details

The Sika 658978 BPO Cream Hardener is a benzoyl peroxide-based catalyst designed for curing amine-accelerated polyester resins and fillers. This professional-grade hardener delivers reliable performance for marine, automotive, and composite repair applications.

Key Features:

  • Benzoyl peroxide (BPO) cream formulation for consistent mixing and application
  • Enables rapid hardening and de-molding, even in low temperature conditions
  • Red color for easy visual confirmation of thorough mixing
  • 4 oz tube size provides precise dispensing and extended shelf life
  • Compatible with amine-accelerated polyester resins and body fillers

This hardener must be used in conjunction with compatible polyester resin products. Mix ratio should follow resin manufacturer specifications, typically 1-2% by volume. Ideal for fiberglass repairs, gel coat applications, and composite fabrication work.

The RV toilet seat that I ordered didn't arrive. I did get the wrong one and need to send back this one. I gave the part # and the size when I ordered and the one that arrived was 6" to big. Thank you Bill

Easy to understand. Quick and clean.

Great prices and quick shipping. Excellent tracking updates. I'm very satisfied.

Fast and easy
