In the silicone industry, when people talk about platinum catalysts, the first name that often comes to mind is the Betely CAT-SPL-XXX series.
But what you might not know is that this series is actually a whole "family," covering a full range of concentrations from 1500ppm to 20,000ppm to meet the catalytic needs of different processes and formulations.
Today, let's explore why this "low‑key yet powerful" product family has become the go‑to choice in the industry.
Full Series, Precise Matching
The CAT-SPL-XXX series of platinum catalysts is specifically designed for addition‑cure silicone systems, efficiently catalyzing the hydrosilylation reaction between ≡≡Si‑Vi and ≡≡Si‑H. It offers fast curing with no side reactions.
| Specification | Platinum Content | Platinum Grams/Kg | Features | Recommended Applications |
| 1500ppm | 1500ppm | 1.5g | Cost-effective, moderate activity | Silicone inks, general-purpose sealant silicones |
| 3000ppm | 3000ppm | 3g | Lower addition level, high curing efficiency | Thermally conductive silicones, high-performance sealant silicones |
| 5000ppm | 5000ppm | 5g | High activity, extremely low addition level | High-end electronic adhesives, fast-cure systems |
| 20000ppm | 20000ppm | 20g | Ultra-high concentration,High catalytic efficiency | Specialty silicones, high-ratio dilution applications |
From 1500ppm to 20,000ppm, Betely delivers full concentration coverage. Whether you prioritize cost‑effectiveness or ultimate catalytic efficiency, you'll find the perfect match.
High Activity + High Stability – Consistent Across the Series
Regardless of concentration, the CAT-SPL-XXX series provides outstanding stability:
• Effectively suppresses platinum black precipitation, making storage and use safer.
• High resistance to poisons – greater tolerance to nitrogen‑, sulfur‑, and other impurities.
• Excellent thermal stability – remains reliable even under high‑temperature conditions.
• High transparency – does not affect the final product's appearance.
Different Concentrations, Different Strategies
In practice, each concentration has its own advantages:
• 1500ppm / 3000ppm: Suitable for conventional addition‑cure silicone systems – moderate addition level, cost‑effective.
• 5000ppm: High activity with significantly lower addition level – ideal for high‑end applications demanding high system purity.
• 20,000ppm: Ultra‑high concentration for extreme catalytic efficiency – perfect for specialty silicones or processes requiring substantial dilution.
This is why Betely platinum catalysts cover a wide market, from silicone inks, sealants, and thermally conductive silicones to high‑end electronic adhesives.
Flexible Packaging, Safe Handling
Packaging options are flexible and diverse: 1kg, 4kg, 10kg, and other specific sizes to suit different production scales. On the safety front, Betely provides detailed TDS and MSDS to give customers peace of mind.
Conclusion
The success of the CAT-SPL-XXX series isn't built on gimmicks – it's built on:
• Proven stability through years of market validation.
• Full‑range concentration coverage.
• User‑friendly design that adapts to customer processes.
Whether you need the cost‑effectiveness of 1500ppm or the high efficiency of 20,000ppm, Betely offers a reliable solution.
