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 finishing resin 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
      • Drums are available. Please call for pricing.


        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. 
        • Fiberglass Warehouse Ortho Polyester Resin is guaranteed for 3 months but should last 6-12 months if stored properly.

         

        ***Always try out a small test batch first.  Working with resin is more of an art than a science***

        Great product

        This stuff is the real deal. The description is dead on. Remains tacky between coats making it super easy to lay up.

        High quality

        This is a high quality polyester resin. Perfect for fiberglass 1708 and CSM laminating. Excellent wetting out and curing properties. I add 1 percent of MEKP to the resin. You can layup multiple wet layers or add layers to cured layups with out issue. I also have not found the need to use wax or PVA after the final layup for curing.

        Question: Do I need to sand between layers?

        Answer: No. This resin does not contain wax which makes it unnecessary to sand between layers.

        Question: What do I do to get a tack free finish on the final layer?

        Answer:You can add wax/ surface seal for the final layer or use a polyester finishing resin.
