BHP Hardener – For Polyester and Gelcoat

BHP Hardener is a universal hardener specially formulated for use with polyester, vinyl ester, gelcoat and topcoat. It ensures a controlled and efficient curing process for a durable end result.

Usage & Dosage:

• Recommended addition: 1–2% hardener to the total amount of base material.
• Temperature dependence: The dosage can be adjusted slightly depending on the working temperature (lower temperatures require more hardener, higher temperatures require less).
• Areas of use: Perfectly suited for repairs with both fiberglass and filler materials.

Important: Be sure to mix the hardener thoroughly to avoid soft spots in the finished surface. Please use a digital scale for precise dosing.
