3. Scratch-Resistant Performance: Gentle on glass surfaces, preventing scratches while maintaining strong ink transfer, protecting lens integrity and reducing scrap rates by 18%.
4. Integrated Solution Compatibility: Works seamlessly with our Liquid Pad Printing Silicone and Silicone Potting Compound, enabling integrated workflows for glass lenses with electronic components (e.g., smart glasses).
5. Exceptional Durability: Wear-resistant and solvent-resistant, supporting 4000+ printing cycles to reduce silicone pad replacement costs and boost production efficiency.
6. Optical Safety Compliance: Non-toxic, odorless, and free of corrosive substances, meeting RoHS and REACH standards, safe for optical product manufacturing.
How to Use
1. Thoroughly clean the glass lens printing pad mold, wipe dry, apply a thin layer of mold release agent, and place it on a level surface.
2. Mix Silicone for Glass Lens Printing (A component) with silicone oil (adjust for desired adhesion) and curing agent (2-3% of total weight) in a clean container, stirring evenly for 2-3 minutes.
3. Slowly pour the mixed compound into the mold, ensuring full coverage of the pad shape (optimized for glass lens curves), and avoid air bubbles.
4. Cover the mold with a dust-proof board and cure at room temperature for 3-4 hours. Demold gently once fully cured.
5. For smart glass lenses, pair with our Electronic potting compound or Silicone Potting Compound for post-printing electronic component protection.
Application Scenarios
Widely used for printing patterns, logos, and functional textures on:
• Optical glass lenses (eyeglasses, sunglasses)
• Smart glass lenses and electronic display glass
• Automotive glass lenses (headlight, sensor lenses)
• Industrial optical lenses (cameras, measuring instruments)
• Decorative glass lenses and craft glass products
When paired with our Silicone Potting Compound, it offers versatile solutions for manufacturers producing optical and electronic-integrated glass products, reducing supplier complexity and optimizing procurement efficiency.
