RAPID CURING Surfaces are ready for topcoats in one to two hours - some even faster with no need to wait! DEEP PE NETRATION Low viscosity allow s sealer to penetr ate surfaces for a more complet e seal. HI GH COMPATIBILITY Versatile to work with your substrate and your choice in topcoat lacquers, urethanes, polyesters, vinyl esters, and most epoxies. S A FE TY & HANDL I NG Duratec Clear Vinyl Ester Sealer is extremely flammable. Do not apply near sparks, open flames or heat. Keep area ventilated. Do not smoke. Avoid continuous breathing of vapor. Duratec Clear Vinyl Ester Sealer contains ingredients which could be harmful if mishandled. Contact with skin and eyes should be avoided and necessary protective equipment and clothing should be worn. Individuals should wash with soap and water before eating or drinking. All containers should be properly labeled to prevent accidental ingestion or improper disposal. Individuals should reseal any partly used material back in the container. Store under cool, dry conditions and away from open flames and high temperatures. For more detailed instructions on storage, please see the MSDS sheet. DURATEC CLEAR VINYL ESTER SEALER P ROD UCT # 1800 * DE S CRI P TION Duratec Clear Vinyl Ester Sealer is designed to provide excellent performance in any situation requiring high heat resistance and/or good corrosion resistance. Designed to promote better adhesions for unsaturated polyester and vinyl ester coatings. 909-546-1160 hawkeyesales@hawkeyeind.com PO BOX 415, BLOOMINGTON, CA 92316 WWW.DURATEC1.COM SAVE TIME AND ADD QUALITY TO YOUR SURFACE PROFILE! POLYE ST E R OP T IO N 823 Crystal Clear Sealer The sealer for processes with an HDT below 180 F. PRODUCT PROPERTIES All time calculations are based on temperatures of 77 F, 25 C Lab tested with Norox 925 MEKP * This product was once labeled as 1800A. The A was removed in 2020 but no changes were made to t he product formulation. DURATEC CLEAR VINYL ESTER SEALER AP PLIC ATION GUIDE | PR ODUC T # 1800 Prepare T emperature should be at least 64 F. Low temperatures extend cure time. Ensure the surface is clean and free of both chemical and environmental contaminants. If needed, slightly sand the surface with 120-220 grit and then wipe off surface with a clean (not tack) rag. Mix the Duratec Clear Vinyl Ester Sealer at a low speed for at least 3 minutes prior to catalyzing. Catalyze before use using MEKP catalyst at 2% by weight. Norox 925 or 925H have yielded good results. Due to the rapid gel time, catalyze only the amount that can be applied within 15-18 minutes. NOTE: Higher temperatures yield a shorter pot life and gel time, while lower temperatures yield a longer pot life and gel time. Apply Sealer Roll, brush, or spray the sealer on. If spraying, apply using air-assisted or airless spray at lowest practical pressure. Wipe away any excess using a clean white cloth or paper towel. Do not use tack rag. Film thickness should be less than 2 mils on the surface. Topcoating (Urethane, Polyester, Vinyl Esters) In general, sealer will be ready to topcoat within an hour or two, but may be ready faster depending on amount of sealer used and ambient temperature. Sanding the sealer prior to topcoating is not necessary if the time between sealing and topcoating is less than eight hours. If more than 8 hours have passed, we suggest sanding with 180-200 to provide mechanical tooth for the bond. Topcoating (Epoxy) Adhesion between the Duratec Clear Vinyl Ester Sealer and epoxy is dependent on a mechanical bond with the epoxy rather than a chemical bond. We advocate for a cure time of at least eight hours. Abrade the surface with sandpaper (180-220) prior to topcoating with epoxy. Duratec Clear Vinyl Ester Sealer is not designed for direct exposure to sunlight or other strong UV sources. The following use instructions are broad to address multiple applications. We recommend testing for product compatability with your process. Please contact our Tech Team at (909) 546-1160 with any questions.
