Resin Properties

• Resin Type: General purpose polyester laminating resin
• Color: Amber-Brown
• Cures To: Hard, rigid polyester finish
• Usage: Small repairs, patching, mold repairs, hobby fiberglass work
• Compatibility: Works with fiberglass mat, cloth, and other polyester-compatible materials
• Catalyst: MEKP (included with all sizes)
• Viscosity: Medium (typical of GP polyester)
• Odor: Typical polyester/styrene odor during cure

Application Notes

• Designed for non-critical repairs and small fiberglass builds
• Applies well by brush, roller, or squeegee
• Good wet-out characteristics on mat and cloth
• Cure time, color, and working time may vary slightly between batches
• Ideal when keeping project costs low is a priority
• Not intended for high-load or structural laminations

Cure Information

(Exact times vary based on catalyst percentage, temperature, and humidity.)

• Catalyst: MEKP
• Typical Working Temperature: ~70–80°F
• Cure Characteristics: Rigid cure similar to standard polyester resin
  Notes: Cooler temperatures slow the cure; warmer temperatures accelerate

Sizes come with corresponding MEKP catalyst:

• 1 Quart ≈ 1 oz catalyst
• 1 Gallon ≈ 2 oz catalyst
• 5 Gallon ≈ 6 oz catalyst

Safety

• Use only in a well-ventilated area
• Polyester resin contains styrene — avoid inhalation
• Wear gloves and eye protection
• Keep away from sparks, flames, and heat sources
• Follow all MEKP handling and storage recommendations
