Product Features & Advantages
High-Precision Printing: Low viscosity and excellent fluidity ensure full mold filling, while zero shrinkage guarantees sharp, consistent pattern replication—ideal for fine electronic textures.
Durable Performance: Infused with DuPont , it offers high-temperature resistance (up to 200℃), wear resistance and oil/solvent resistance, extending pad service life and reducing replacement costs.
Superior Elasticity: Fine colloid texture with no impurities ensures strong rebound, enabling thousands of prints without deformation—enhancing production efficiency.
Easy Room-Temperature Curing: No special equipment required; curing time adjusts with hardener dosage (2%-3% of total weight), simplifying workflow and lowering energy consumption.
Eco-Friendly Compliance: Manufactured under ISO9001/CE/UL certifications, free of harmful substances, meeting global electronic industry environmental standards.

How to Use (Step-by-Step)
Mold Preparation: Thoroughly clean the pad printing head mold with a degreaser, dry completely, and apply a thin layer of release agent for easy demolding.
Material Mixing: Blend the silicone base (Component A) with silicone oil (adjust ratio for desired hardness: 100:30 for soft pads, 100:10 for hard pads). Add 2%-3% curing agent (Component B) and stir vigorously for 2-3 minutes.
Defoaming: Place the mixture in a vacuum chamber for 5-10 minutes to remove air bubbles—critical for avoiding printing defects.
Casting & Curing: Pour the bubble-free mixture into the mold slowly, cover with a plate, and cure at room temperature for 3-4 hours before demolding.
Optimal Usage: Select pad size/hardness based on pattern dimensions (soft pads for fine patterns, hard pads for large/bold designs) to maximize printing quality.
Application Scenarios
This product is tailored for the electronics industry, widely used in:
High-end precision electronic accessories (e.g., phone cases, keyboard buttons)
