The Ultimate Balance of Flexibility and Transparency | Sanqi International HG Varnish: Ensuring Every Layer of Thick Plate Printing Stands the Test
ln the screen printing process for 3D thick plates, the base coating is often the invisible key that determines the success or failure of the final product. An excellent base material must not only possess outstanding adhesion and flexibility but also feature a transparent texture and stable weather resistance. Sanqi International's HG Water-Based Transparent 3D Varnish was born to overcome this process pain point. Based on an eco-friendly water-based system, it constructs a tough and transparent elastic network at the microscopic level, providing solid support and lasting protection for thick plate printing.
True quality stems from the ultimate pursuit of details and absolute respect for the substrate. In its wet state, the HG Water-Based Transparent 3D Varnish presents as a fine, milky white paste with a uniform texture that is easy to stir and blend, easily meeting the application requirements of thick plate screen printing. Once cured into a film, 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 layers of the printed pattern to be perfectly presented. This "invisible" supporting force not only enhances the visual aesthetics of the product but also seamlessly integrates the printing layer with the substrate, delivering a warm touch and superior texture.
As a professional base coating material, the HG Water-Based Transparent 3D Varnish demonstrates reassuring hardcore strength in its physical properties. At room temperature, it can effortlessly withstand up to 100,000 repeated bending cycles. Even in an extreme cold simulation chamber at -20°C, it still maintains 40,000 bending cycles without cracking. This exceptional flexibility ensures that the printing layer is impervious to daily bending and stretching, completely eliminating the risks of cracking and delamination. Meanwhile, its tensile strength remains stable above 3.5KG, forming a strong molecular-level adhesion with various substrates such as shoe uppers, leather, and fabrics. This fundamentally prevents the printing layer from peeling off or breaking due to external forces, significantly extending the service life of the product.
Facing complex and ever-changing usage scenarios, the HG Water-Based Transparent 3D Varnish also exhibits stable weather resistance throughout its entire lifecycle. Its anti-yellowing performance reaches Level 4 or above, ensuring that the printed products remain white and clear without yellowing during long-term exposure to light and storage. Its outstanding hydrolysis resistance makes it impervious to the erosion of humid environments; even after soaking in rainwater or daily washing, it maintains stable performance without turning white or sticky. Furthermore, it can withstand high-temperature hot pressing at 120°C, perfectly adapting to various downstream processing techniques without bubbling or deforming, providing a high degree of process tolerance for production lines.
From formulation R&D to performance refinement, all core parameters of the HG Water-Based Transparent 3D Varnish strictly adhere to professional printing standards. Its solid content is stably maintained at 50% to 55%, ensuring uniform and controllable film thickness, and providing full and three-dimensional support for thick plate printing. With a mild pH value between 7 and 8.5, it is extremely friendly to various substrates, causing no corrosion or irritation. A fineness of less than 25 microns ensures smooth screen passing during printing without clogging, effectively safeguarding both production efficiency and printing precision.
Whether it is the 3D lines on athletic shoe uppers, the decorative patterns on fashionable luggage, or the thick plate printing on various leathers and fabrics, Sanqi International's HG Water-Based Transparent 3D Varnish escorts the printing process with its stable performance and excellent results. It is more than just a transparent base coat; it is a profound embodiment of Sanqi International's manufacturing philosophy of "eco-friendliness, flexibility, and transparency." Choosing HG means choosing professionalism and craftsmanship to lay a solid and transparent foundation of quality for every printed product.
