Strong Foundation, High Transparency & Color Protection | Sanqi International HG-6 Water-Based Transparent 3D Varnish

In the thick-plate 3D screen printing process, the priming stage often determines the final texture and service life of the finished product. An outstanding primer must not only deliver exceptional adhesion and flexibility but also possess a transparent finish and stable weather resistance. Sanqi International's HG-6 Water-Based Transparent 3D Varnish is the comprehensive upgrade of the HG series, purpose-built to tackle the complex pain points of thick-plate printing. Based on high-polymer water-based resin, it constructs a tough yet transparent elastic network at the microscopic level, providing solid support and lasting protection for thick-plate printing.
True quality stems from the relentless pursuit of detail and full respect for the substrate. In its wet state, HG-6 Water-Based Transparent 3D Varnish presents as a fine, uniform paste that is easy to stir and blend, effortlessly adapting to the application requirements of thick-plate screen printing. Once cured, it transforms into a completely transparent elastic film that does not obscure the original texture and color of the substrate, allowing the three-dimensionality and color layering of the printed pattern to be perfectly showcased. This "invisible" support not only enhances the visual appeal of the finished product but also seamlessly integrates the print layer with the substrate, delivering a warm touch and outstanding texture.
As a professional priming material, HG-6 demonstrates reassuring, hardcore physical performance. At room temperature, it effortlessly withstands up to 100,000 repeated bending cycles, and even in a -20°C extreme cold simulation chamber, it maintains 40,000 bending cycles without cracking. This exceptional flexibility ensures that the print layer remains impervious to bending and stretching during daily use, eliminating the risks of cracking and delamination. Meanwhile, its tensile strength consistently exceeds 3.5KG, forming a robust molecular-level bond with various substrates — fundamentally preventing the print layer from detaching or breaking under external force, and significantly extending the product's service life.
Faced with complex and ever-changing usage scenarios, HG-6 also demonstrates stable weather resistance throughout its entire lifecycle. Its anti-yellowing performance reaches Level 4 and above, resisting yellowing under prolonged light exposure and storage, keeping prints consistently white and transparent. Its excellent hydrolysis resistance allows it to withstand moisture without degradation — even after rain soaking or routine washing, it maintains stable performance without whitening or becoming tacky. Even more impressively, it withstands hot pressing at 150°C, perfectly adapting to various downstream processing techniques without bubbling or deformation, providing a generous margin of process tolerance for production workflows.
From formulation R&D to performance refinement, every core parameter of HG-6 strictly adheres to professional printing standards. Its solid content is stably maintained at 50%–55%, ensuring uniform and controllable film thickness with fast drying — providing full, three-dimensional support for thick-plate printing, effectively reducing the number of print layers and boosting production efficiency. With a fineness below 25 micrometers, it ensures smooth mesh passage during printing with minimal screen clogging, effectively safeguarding both production efficiency and printing precision. Its pH falls within a mild range, making it extremely substrate-friendly with no corrosion or irritation.
Whether it's 3D lines on athletic shoe uppers, decorative patterns on fashion bags, or thick-plate prints on various leathers and fabrics, Sanqi International's HG-6 Water-Based Transparent 3D Varnish safeguards the printing process with its stable performance and outstanding results. It is more than just a transparent primer — it is Sanqi International's profound commitment to the manufacturing philosophy of "eco-friendly, flexible, and transparent." Choosing HG-6 means choosing professionalism and craftsmanship to lay a solid, transparent foundation of quality for every printed product.
