For general-purpose epoxy-resin system applications.
System Three Multipurpose Epoxy has excellent pot life and cure-time control. When selecting a hardener, consider the minimum temperature expected during application and the required pot life. Combine different System Three Multipurpose Epoxy Hardeners to provide a continuous range of cure times. Refer to The System Three Epoxy Book to make a proper selection. System Three Multipurpose Epoxy works great for wood construction and repair, for gel-coat blister repair, and for general fiberglass repair. Use with any of the slow, medium, or fast hardeners.
Preparation
Surface must be sanded and clean, dry and free of oil-based paint, oil, wax, dust and other contaminants. Do not wipe with tack cloth.
Mixing
Ratio by volume is 2-parts resin A to 1-part hardener B. Ratio by weight is 100 parts resin A to 44 parts hardener B. Do not alter mixing ratio. Mix the resin and hardener together for at least 3 minutes. Large batches need longer mixing for uniform cure.
Application
Best results will be obtained @ 75ยบ F. To avoid waste, mix only the quantity that can be used within the cure time based on the hardener (10, 25, or 60 minutes). Using a roller, brush, squeegee, or spreader apply mixed resin/hardener to surfaces.
Cure Time
Tack-free cure in 2-8 hours; full cure in 7-to-14 days.
Caution! Vapors harmful. Keep out of reach of children.
