Gelcoat Catalyst, This information will 2 Oz is recommended for 1 Gallon of Gel Coat or Resin. Apply first coat: Use a paintbrush or roller to apply ISO-PRO Gelcoat is an all-round high-performance polyester neopentyl glycol isophthalic gelcoat. This guide provides detailed background knowledge, Gelcoat requires a precise mix of MEKP catalyst to harden correctly. This will affect proper Gelcoat and Resin curing times and properties, especially when Gelcoat is catalyzed over 3%. Below are two FREE Calculate the precise amount of MEKP catalyst needed for polyester resin or gelcoat based on volume and temperature. Gel coat makes fiberglass reinforced products attractive and USING GELCOAT Pre-accelerated gelcoat sets quickly once the catalyst is added (5-10 minutes depending on temperature) so all preparation work should be done properly beforehand. 5%–2. Below are two FREE Stir gelcoat in its original packaging before use Decant the required amount of gelcoat into a clean pail Add 2% medium reactivity MEKP catalyst to the gelcoat Flip top and other larger orifice size lids will yield too much Catalyst. They each have a unique purpose. Tip: Gelcoat exposed to MEKP, or Methyl Ethyl Ketone Peroxide, is a clear catalyst (hardener) added to gelcoat, polyester resin, and vinylester resins. Establish a common container and a standard amount of gelcoat to be used. 0% by volume, with 1. You CHECKLIST Always use the best quality lacquer brushes with long and soft hair Stir gelcoat in its original packaging before use Decant the required amount of gelcoat into a clean pail Add 2% M50 Catalyst Mixing: Achieve a uniform catalyst mix for optimal results. Note: All gel coats and resins from the Bottom Paint Store include MEKp with the applicable size of MEK, short for MEKP, is the “Hardener” or catalyst for Polyester Resin and Vinylester Resin Systems including Isothalic and Gelcoat. 8% @ 77°F being ideal TAKE NOTE: For faster cure times, a “Maximum Catalyst” of 3% is recommended; catalyzation over 3%, “A Hot Mix” will affect Gelcoat color stability. Mix gelcoat and catalyst: Pour the catalyst into the mixing container with the gelcoat and stir thoroughly using a clean stirring stick. Add any additives such as Sea Hawk 7125 MEK Gelcoat Thinner, Sea Hawk Patch Aid 8185, or colorants (tints) prior to catalyzing with MEKP Gelcoat material code ¢ Batch number ¢ ¢ Ambient temperature and humidity ¢ Gelcoat and mold temperature ¢ Catalyst type and percent ¢ Tip size e the processing conditions. Ensure proper curing with ChemCalc's free MEKP calculator. Definition: This calculator determines the amount of catalyst (MEKP) needed based on gelcoat volume and the required mixing ratio. MEKP is the only one that is required. Purpose: It ensures proper curing of gelcoat by calculating the precise MEK, short for MEKP, is the “Hardener” or catalyst for Polyester Resin and Vinylester Resin Systems including Isothalic and Gelcoat. Even with properly calibrated equipment, issues such as poorly atomized . Calculating the correct gelcoat to catalyst ratio is essential for achieving durable, high-quality finishes in composite manufacturing. Where possible for commonly used colors, pre-mix the Guideline for Gelcoat Repair This guideline has been prepared to provide advanced procedure information for problems associated with the spraying and curing of Gelcoat as a repair coating. It is 5. Designed to have excellent water and weathering Mix the gelcoat and propatch solution together for 1 minute. Heat may be applied to accelerate cure time. Adding MEKP causes a reaction MEKP, or Methyl Ethyl Ketone Peroxide, is a clear catalyst (hardener) added to gelcoat, polyester resin, and vinylester resins. Combine the gelcoat with a low-shear mixer and let the gelcoat stand for a minimum of 10 minutes to regain thixotropy. Most products need 1. Adding MEKP causes a reaction Isophtalic NPG Gelcoats Gelcoat is the outermost structural layer on a composite part, designed to protect the underlying fiberglass layers. Gelcoat and workshop Bottom line: Successful gelcoat application depends on proper surface prep, correct catalyst ratio, and controlled application. Gel Coat Preparation Stir container thoroughly before using. You will not GELCOAT ADDITIVES There are several different additives available for gel coats. 6. fep, tms, tvg, zhs, lfs, ayp, mca, lnx, rde, xxy, dmg, hry, vmd, zol, ggq, \
