HOW IT WORKS
The 3 steps to follow when using
Ink Formulation and Printing
Stir thoroughly: After opening the can, stir the contents thoroughly. Two-component inks must be mixed in the specified ratio.
Curing conditions
Low-temperature curing: Cure at 100–130°C for 20–30 minutes, or cure at 180°C or above for 10–15 minutes (depending on ink type).
Storage and Security
Sealed Storage: Unused ink must be sealed and stored at 0-10°C. Avoid high temperatures and direct sunlight.
Characteristics
Three Key Benefits of UV Invisible Ink
Premium Performance & Flexibility
Silicone is a high-performance, flexible, and durable material with a premium feel. It offers excellent elasticity and long-term stability, making it ideal for applications that require both softness and strength without deformation.
Outstanding Resistance & Durability
Silicone is highly resistant to heat, cold, UV exposure, water, and chemicals. Even under harsh environmental conditions, it maintains its original shape, texture, and color, ensuring long-lasting performance and reliability.
Apparel & Footwear Uses
Non-toxic and skin-friendly, silicone is widely used in the clothing and footwear industries. Common applications include T-shirt printing, underwear anti-slip patterns, shoe upper printing, heat-transfer labels, and stretch fabrics, delivering both functional performance and a high-end visual effect.
Key considerations for screen printing UV Invisible Ink:
Screen Selection and Plate Making
1. Mesh count: Recommended 80-120 mesh. Excessively high mesh counts may prevent silicone from passing through, while excessively low counts may cause uneven flow. 2. Photoresist thickness: Requires 0.1-0.5mm to enhance three-dimensional effects. Adjust based on sample thickness.
Ink Types and Curing
1.Two-component silicone: Requires mixing of A/B components, baking at 120-160°C, offers strong adhesion but requires high-temperature resistant materials. 2.One-component silicone: Air-dries naturally (6-10 minutes), suitable for fabrics or plastics that cannot withstand high temperatures.
Printing Process Control
1. Ink Layer Thickness: Conductive ink must be >30μm, with resistance <200Ω (4mm spacing) 2. Squeegee Hardness: Approx. 55° Shore A, speed 12-24 cm/s, to prevent deformation of curved key bodies 3. Design Specifications: Character spacing should not be too close; background area should be 0.1-0.2mm smaller than surface color to prevent adhesion
Environment and Safety
1. VOC Restrictions: Must comply with standards such as EU Directive 2004/42/EC to control volatile organic compound emissions. 2. Food Contact Safety: For food packaging applications, must meet migration limits and heavy metal thresholds specified in GB 4806.14-2023.
Frequently Asked Questions
1. Color Variation: A 0.1μm variation in ink layer thickness can cause noticeable color differences, requiring strict control of ink-water balance. 2. Screen Clogging: Excessively rapid solvent evaporation may clog mesh openings; add defoaming agents (e.g., SSYK defoamer at 0.5-1.0%).
