Metroflex Catalyst

• BPO powder catalyst for Metroflex resin
• 16g measuring scoop included

Metroflex Catalyst is the BPO (benzoyl peroxide) powdered hardener used to initiate the cure of Metroflex flexible roofing resin. Unlike liquid MEKP catalysts used in standard polyester resins, this powdered catalyst is blended specifically for the Metroflex system and is supplied pre-weighed for accurate dosing.

The correct catalyst ratio is critical to achieving the right pot life and cure time - too little and the resin may remain tacky; too much and the working time may be insufficient to complete the section. In hot weather, Metroflex Summer Inhibitor should be used alongside the catalyst to extend the working time. Always follow the Metroflex application guidelines for the correct dosage at the prevailing ambient temperature.
