Gel Coat Additives

Acetone is a powerful solvent used in the composite industry as the standard for cleaning and degreasing. It will dissolve and remove epoxy, polyester, and vinyl ester resin from tools, brushes, and surfaces. It will also effectively remove grease and wax for surface preparation prior to bonding or repair. Available in 5 gallons, 1 gallon, and 1 quart.

Prestec 27x1 is a clear top coat that doubles as a gel coat additive to ensure air cure and a significantly harder surface when fully cured than gel coat alone.

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

Methyl Ethyl Ketone (MEK) is an effective solvent in gel coats that allows them to spray and level significantly better than acetone in spraying applications.

Styrene can be added to gel coats and resins in order to thin them down for various applications.
