HY-928 is an addition cure high precision grade Pad Printing Silicone from HYC-Silicone's HY-9 series. Made with premium platinum catalyst and high-purity Silicone raw materials, it cures with less than 0.1% shrinkage, delivering extremely high dimensional accuracy and perfect reproduction of micro-text and fine patterns. For industries with extremely high printing precision requirements — such as high-end cosmetic packaging, precision medical devices, and micro-electronic components — ordinary condensation cure silicones often fall short in shrinkage and precision. HY-928 addition cure high precision silicone is specifically engineered for these demanding applications.
Key Features
1. Ultra-High Precision: <0.1% shrinkage, highly accurate and stable pad dimensions, exceptional fine pattern reproduction
2. Platinum Addition Cure: No low-molecular by-products, no contamination to printed product surfaces
3. Excellent Detail Reproduction: Micro-text and fine line patterns are sharp and clear with clean edges
4. Medium Hardness: Shore A 15-20°, highly versatile — works on flat surfaces and mild curves
5. Excellent Rebound Resilience: No deformation after repeated pressing, long pad service life
6. Uniform and Delicate Ink Transfer: Stable ink transfer, full and clear patterns
7. Safe and Eco-Friendly: Meets RoHS, FDA and related standards, safe and reliable

• Precision electronics printing — micro-component marking, IC chip identification
• Watch and eyewear printing — dial scales, temple logos, fine line patterns
• Stationery and office supplies — fountain pens, high-end stationery fine decoration
• Other applications with extremely high printing precision requirements
How to Use
1. Stir Part A and Part B thoroughly before use
2. Weigh accurately at 1:1 weight ratio, keep error within ±2%
3. Mix gently for 2-3 minutes to avoid introducing too many bubbles
4. Degas under vacuum for 5-8 minutes to ensure complete bubble removal
5. Pour slowly along the mold wall to minimize bubble formation
6. Cure at room temperature for 12-24 hours, or accelerate at 60°C for 2 hours
7. After full cure, let rest 4 hours before demolding for best results
Notes
• Addition cure silicone is sensitive to sulfur, tin, amines and lead — keep tools and environment free of these contaminants
• Use dedicated tools for Part A and Part B — never mix tools to prevent cross-contamination
• For high precision printing, use high-quality molds — mold quality directly affects pad precision
• Use opened material promptly, seal remaining material and store in cool place
• Always do test prints before batch production to confirm results
