Product Overview
As a flagship product in HONG YE SILICONE’s pad printing lineup, this Electronic Pad Printing Silicone is a specialized liquid two-component (A/B) material designed to craft high-quality pad printing heads. The core principle of pad printing lies in using the silicone pad as a carrier to transfer patterns from steel plates to electronic products—solving the challenge of printing irregular or fine designs. Our product stands out for its pure colloid (no impurities/granules), ensuring consistent performance in high-volume electronic manufacturing. Backed by 20+ years of silicone R&D expertise, it balances durability and print precision, making it a trusted choice for global electronics manufacturers.
Product Features & Advantages
Superior Print Clarity: Low viscosity (4500-7500 mPa·s) ensures seamless mold filling, while zero shrinkage preserves intricate details (down to 0.08mm lines) for sharp electronic logos and textures.
Extended Service Life: Reinforced with high-wear silicone additives, it withstands 5000+ prints per pad without deformation or oil bleeding—reducing replacement costs by 35%.
Efficient Curing: Room-temperature vulcanization (3-4 hours) eliminates the need for high-temperature equipment, cutting energy consumption and streamlining production workflows.
Broad Compatibility: Works with solvent-based, UV-curable and water-based electronic inks, adapting to diverse printing processes.
Eco-Friendly & Safe: RoHS-compliant, free of heavy metals and toxic substances, meeting global electronic industry environmental standards.

How to Use (Step-by-Step)
Mold Preparation: Clean the pad mold with a non-toxic degreaser, dry thoroughly, and apply a thin layer of release agent to ensure smooth demolding.
Material Mixing: Blend Component A (silicone base) with silicone oil (adjust ratio: 100:15 for medium hardness, 100:25 for softness). Add 2%-3% Component B (curing agent) and stir vigorously for 2-3 minutes.
Defoaming: Place the mixture in a vacuum chamber for 6-8 minutes to remove air bubbles—critical for avoiding pinholes in the pad.
Casting & Curing: Pour the bubble-free mixture into the mold slowly, cover with a clean plate, and cure at room temperature for 3-4 hours before demolding.
Optimal Application: Select pad size/hardness based on pattern: small/fine patterns use soft pads (16A°-18A°), large/bold designs use hard pads (22A°-24A°).
Application Scenarios
This product is tailored for the electronics industry, widely used in:
