HV'ART Advanced Hardener Crosslinker is a versatile additive that boosts the performance of coating systems. Designed for use in both HV'ART basecoats and topcoats, it initiates a powerful chemical reaction, creating a tough, resilient film with enhanced resistance to wear, abrasion, and chemicals. With its medium drying time and long pot life, it provides professionals with the flexibility needed for large or complex projects, ensuring a durable, high-quality finish. The HV'Art Advanced Additive Hardener (HVCRHRD 1%) is and optional additive to further increase the chemical and mechanical resistance of the coating. Meant to be added to the final coat of a surface finish to increase hardness. It is not advised to add to any prior coats, as this can impede best inter-coat adhesion. When added at a concentration of 0.5-1% it considerably improves hardness, abrasion resistance, resistance to aggressive household chemicals, and blocking resistance against tannins or bleed from the substrate. System HV’ART Advanced Hardener Crosslinker is recommended as an additive as part of an Interior Coatings System. Compatibility: Gesso Style Primer, Gesso Style Factory Primer, Decorative Canvas Basecoat, Lacquer Paint/Furnitura and Crystal Lacquer. DO NOT USE with Architura or Lacquer Glaze. Decorative Designs / Finishes: Primer / Undercoat Additives* HV’ART Advanced Gesso Style Factory Primer (GSF) / HV’ART Advanced Gesso Style Primer / Undercoat (GSP) Basecoat / Mid coat HV’ART Advanced Decorative Canvas Decorative Coat N/A Topcoat Additives* HV’ART Advanced Crystal Lacquer Standard Finishes: Primer/Undercoat Additives* HV’ART Advanced Gesso Style Factory Primer (GSF) / HV’ART Advanced Gesso Style Primer (GSP) Topcoat Additives* HV’ART Advanced Furnitura Please refer to the relevant Technical Data Sheets for advice on suitable coating systems. Some wood species may exhibit discoloration due to natural extractives, which can be prevented by using an isolating sealer and mid-coat. Ensure all external materials in contact with the coating system, such as putty, adhesive tapes, sealants, and cleaners, are tested for compatibility by the user to avoid any adverse reactions. More Info The HV’ART Advanced Hardener Crosslinker is a versatile, high-performance additive that significantly boosts the durability and longevity of a wide range of coating systems. This general-purpose crosslinker initiates a powerful chemical reaction, transforming both basecoats and topcoats into a tough, resilient film. By creating a dense network of chemical bonds, it dramatically improves the coating’s resistance to daily wear, abrasion, and harsh chemical exposure. Its balanced formula offers an ideal medium drying time for controlled application, while a long pot life ensures the mixed product remains usable for extended periods, reducing waste and giving professionals the flexibility needed for large-scale or intricate projects. Engineered for reliability, the HV’ART Advanced Hardener Crosslinker additive is the perfect solution for achieving professional-grade results. It’s an essential component for professionals who demand exceptional quality and lasting protection from their coatings. Whether used in a protective basecoat or a final high-gloss topcoat, this single product streamlines your workflow and guarantees superior performance. It is specifically designed to work with the HV’ART system of products, a range of water-based, eco-friendly paints and lacquers used to create specialised decorative finishes. When added to HV’ART basecoats and topcoats, it enhances the final finish’s durability, hardness, and chemical resistance. When used in the final coat, it also improves stain-blocking properties and provides excellent abrasion resistance. Areas of Use The HV’ART Advanced Hardener Crosslinker additive is designed to be added to your chosen basecoat or topcoat. Its general-purpose nature and long pot life make it a dependable choice for a variety of projects. Always refer to the product’s technical data sheet for specific mixing ratios and application instructions to achieve optimal results. Prep & Applicaiton Application Add the hardener by blending very well with a mechanical mixer. Use the product within 3 hours after adding the hardener. Do not use the remaining product after such a time. On application, the temperature of the product, the substrate, the coating and the working environment should never fall below 15°C. Product Type Mixing Ratio % HVCRHRD .5 - 1% Add the additive slowly and under mechanical mixing. When the crosslinker is used in coating systems with quick drying time, the quantity of product to be used must be decided after performing tests on the system and based on the user’s application. Mixing Ratio Up to 1% by volume of HVCRHRD Additive to the coating material, mixed thoroughly for even distribution. For each liter of coating use up to 10ml of hardener. There are two methods of mixing, Straight Mixing & the Dilution Method. See method instructions below. STRAIGHT MIXING: 1% of HVCRHRD Additive of the total volume of the coating material, mixed thoroughly for even distribution DILUTION MIXING METHOD: Measure additive needed (1% of coating) add to water and mix together thoroughly. Then add mixture to the HV’Art coating and mix thoroughly. Note: The dilution method will add 5-10% H20 to the selected coating, thus diluting the coating slightly. The dilution method is best to ensure a full and even mixing of the crosslinker/additive. If coating is already diluted then do dilute further. Application: The coating mixture containing additive should be used immediately after preparation and used within 12 hours. Drying: Recommended temperature – 20°C Relative humidity – 45-65%.
