MEKP Hardener
Industry Standard Catalyst


Methyl Ethyl Ketone Peroxide, or MEKP, is required with all polyester resins, gel coats and vinyl ester resin. It is required in different concentrations as defined for each resin product.

Each resin product is available as a kit with the correct amount of hardener. However, hardener may be purchased individually as shown here.
(DDM-9)  
BPO Hardener
Cream Hardeners


White BPO, Red BPO, and Black BPO are cream hardeners for use with the following Fibre Glast polyester systems:
  • #4100 Polyester Fairing Compound
  • #4115 Carvable Low Density Polyester Filler
  • #4116 Lightweight Polyester Cosmetic Filler
Our kits ship with white hardener, but you can select either Red or Black for use as a mix indicator. All hardeners are easy to use and offer effective rapid reactions.
  • Available in 2 sizes - 1 oz. and 4 oz.

Styrene Thinner
General Purpose Styrene


Styrene is primarily used to thin polyester resin and gel coat before use. This is not a necessary step for the resins or gel coat on FibreGlast.com, but simply a preference for handling purposes.
  • When added to polyester resin, it enables and speeds the resin infusion process for vacuum bagging.
  • Fabricators may thin gel coat 2–5% with styrene to make them more suitable for heavy spray equipment.
 
Styrene Wax
Get a Complete Cure


Add Styrene Wax to non-waxed polyester resin and gel coat to prevent the prolonged tackiness associated with thin sections of polyesters in your composite.

This Styrene Wax is a 5% paraffin dissolved in styrene. When paraffin is added to resin, the wax will rise to the surface and protect the curing resin from the inhibiting action of the air. Once the resin is allowed to fully cure, it must be sanded off prior to any additional applications. Any paraffin on the surface will prevent adhesion of further coats.

Mix #71 at 5% for thin coatings—approximately one to two tablespoons for every pint of resin. When performing repairs below the water line, use with #1040 Hi-Gloss Additive. 
Duratec Clear Hi-Gloss Gel Coat Additive
Spray Gel Coat Like Paint


Duratec® Clear High Gloss Additive can be mixed in a 1:1 ratio with regular gel coat to reduce viscosity and porosity, improve gloss level, and permit a complete open-air cure. It can also be blended with a 15% ratio to tooling gel coats to upgrade mold surfaces, improve gloss retention, increase impact resistance, and reduce heat distortion.

The reduction in viscosity allows gel coats to be sprayed controllably through siphon and HVLP equipment, reducing sanding and polishing time. When used for repairs, this product will result in a low porosity surface.

When making below-the-waterline repairs on boats, for example, we recommend adding our #71 Styrene Wax to maximize hardness.

Requires 2% MEKP. 
Duratec StyroShield Primer
Spray Directly on Styrofoam


Duratec® StyroShield Primer is a polyester primer that is meant to be applied directly to polystyrene foam (also known as Styrofoam). StyroShield contains microspheres that, when cured, insulate and protect polystyrene foam from the chemicals in polyester-based laminating resins, gel coat, and other Duractec products. With StyroShield, low-cost polystyrene can be substituted for urethane foam in plug, mold, and pattern-building applications.

Spray StyroShield using an HVLP gun with a 2.5 mm or larger nozzle. Apply at least 20 mils of StyroShield to ensure complete coverage and surface protection.

When in storage, the microspheres in StyroShield will float to the top and form a hard crust, so thorough mixing is required prior to use. When possible, store StyroShield Primer container upside down.

Requires 2% MEKP.  
Dry Gas Blanket
Extend the Life of Liquids with One Easy Spray


Simply spray Poly Purge Dry Gas Blanket into an open container just before sealing the lid. This displaces the moist air inside the container, extending the shelf life of the contained liquid. Works with urethanes, epoxy resin, polyester resin, gel coat, and vinyl ester resin.
