ORTHO POLYESTER LAMINATING RESIN DETAILS:

Fiberglass Warehouse Ortho Polyester resin is a general purpose orthophthalic (ortho) polyester resin. It cures with a surface tack.  Pre-promoted for curing at room temperature with the addition of methyl ethyl ketone peroxide (MEKP) initiator. Fiberglass Warehouse Ortho Polyester resin has a clear amber tint to it. It cures with a surface tack for better bonding between layers.

VERSATILE USES FOR FIBERGLASS WAREHOUSE ORTHO POLYESTER RESIN:

• Boat construction and repair
• Molding, fabrication and repair of fiberglass laminates
• Spray up process
• Hand lay-up application
• Base resin for polyester fairing putties and structural compounds

EASY APPLICATION:

• Work area and resin should be between 70°F and 75°F for best results.
• Make sure the work area is well ventilated and wear proper safety clothing including gloves and a face mask.
• MEKP catalyst is needed for polyester resin to cure.  It should be added between 1-2% based on the volume of the resin. More or less than this will cause an improper cure.  Cure time and pot life will vary depending on percentage of MEKP added and the temperature of the room.  If 1% MEKP is added, there will be a longer pot life and it will cure slower than if 1.5% or 2% MEKP is added.  Same goes for temperature.  Lower temperatures result in a slower pot life/cure time than if working in higher temperatures.  Orca 200 is promoted to gel in 17-23 minutes at 77°F when catalyzed at 1 percent (approx. 1 tsp per pint).
• Apply using a fiberglass roller, brush, spreader or squeegee
• No need for sanding between layers
• For the final layer, a can be used to create a hard, tack-free surface. Finishing resin contains wax which rises to the top when cured and seals off the air.
• Uncured polyester resin can be removed from tools and equipment with acetone.

AVAILABLE SIZES:

• Quart, Gallon, 4 Gallon

HANDLING AND STORAGE: 

• Closed containers should be stored in a cool, dry place.  It should be stored at temperatures below 75°F and away from sunlight and heat sources.
