Three Seven International HTPU Water-Based Ink | Hard-Core Performance, Elevating Printing Quality
In the production and processing of footwear materials, apparel, luggage, bags, and crafts, ink performance directly determines product aesthetics and durability. It must not only adapt to diverse process requirements but also withstand multiple tests of daily use. Three Seven International HTPU Water-Based Ink, with its stable physicochemical indicators and super weather-resistant durability, has become an excellent choice for multi-industry printing, serving as a core advantage for product quality enhancement.
The performance advantages of this HTPU water-based ink are embedded in every precise parameter. Viscosity is stably maintained in the range of 2.5~3.5 ten thousand, ensuring excellent printing flowability and suitability for various screen printing processes. It prevents screen clogging and sagging, maximizing operational convenience. Solid content of 45~50% ensures excellent film formation and strong adhesion, fundamentally solving issues of ink peeling and delamination. pH value of 7.5~8.5, mildly alkaline, ensures system stability, preventing deterioration during storage and use, and guaranteeing batch printing consistency. Fineness of only 10 microns results in a细腻 (delicate) and flat ink layer, providing a sophisticated printing texture. Paired with high gloss, it enhances the visual effect of finished products. Simultaneously, high opacity easily adapts to different colored base materials, eliminating the need for repeated overprinting and significantly improving production efficiency.
Durability is the core competitiveness of this ink. Targeting the daily folding and bending characteristics of products like footwear and luggage, the ink has undergone rigorous testing. It can withstand 100,000 bends at room temperature and achieve 60,000 bends at -20°C low temperature without cracking or ink loss. It maintains the integrity of the ink layer in both humid southern environments and cold northern climates. Tensile strength reaches above 3.5KG, providing excellent resistance to stretching and tearing, effortlessly handling pulling and squeezing during product use. Simultaneously, the ink possesses triple properties of hydrolysis resistance, heat press resistance, and anti-yellowing. In hydrolysis tests, coating properties remain stable, fearless of erosion by humid environments. It can withstand 180°C high-temperature heat press, adapting to subsequent processing steps without ink melting or deformation at high temperatures. Anti-yellowing tests reach a 4-grade standard, with minimal yellowing or fading under long-term light exposure, keeping product aesthetics consistently "online."
Combining environmental friendliness with adaptability broadens the application scenarios of this ink. Using water as the primary solvent, it is environmentally friendly, meeting industry VOCs reduction requirements and improving the production work environment. Simultaneously, it adapts to the printing needs of multiple industries such as footwear materials, apparel, luggage, bags, and crafts. Excellent printing performance is achieved on various substrates including TPU, fabrics, leather, and more, providing a one-stop solution for multi-category production ink needs.
From process adaptability to quality assurance, from daily use to long-term weather resistance, Three Seven International HTPU Water-Based Ink empowers production in the footwear, apparel, and luggage industries with all-dimensional hard-core performance. As a strong brand deeply rooted in the chemical industry, Three Seven International always takes technology as its core and quality as its foundation, using high cost-performance products to solve practical production pain points in the industry. Choosing Three Seven International HTPU Water-Based Ink makes printing more efficient and quality more stable, building core competitiveness for your products!
