Platinum catalyst drives the hydrosilylation reaction in addition-cure silicone — it links vinyl-containing silicone polymers with Si-H crosslinkers, letting the material cure with no reaction by-products.
Times Silicone makes five grades — TPL-1000, TPL-2000, TPL-3000, PTR-3000, PTR-5000 — so you can match catalytic activity to the formulation and the process.
Key Features
- Efficient hydrosilylation catalysis
- For addition-cure liquid silicone
- Colorless, transparent liquid
- Compatible with silicone formulations
- Multiple activity levels for different processing needs
- Covers conventional, balanced, fast-curing, and inhibition-resistant applications
Platinum Catalyst Series
| Product | Main Characteristics | Typical Applications |
|---|---|---|
| TPL-1000 | Low concentration, flexible dosage | General-purpose silicone, potting, silicone ink |
| TPL-2000 | Balanced activity and working time | Two-component liquid silicone, mold materials |
| TPL-3000 | Stable catalytic activity | Food-grade, daily-use, potting silicone |
| PTR-3000 | Resists catalyst inhibition | Complex formulations, bonding applications |
| PTR-5000 | High catalytic activity | Thin coatings, rapid molding, fast curing |
How to Choose
The right grade depends on cure speed, working time, formulation, substrate, possible inhibitors, production cycle, and dosage. Quick guide:
- Conventional production — TPL-1000 or TPL-3000
- Need a balance of working time and curing efficiency — TPL-2000
- Tough, inhibition-prone formulations — PTR-3000
- Fast-curing, high-activity needs — PTR-5000
Why Times Silicone?
Instead of one universal catalyst, we offer five grades, so you pick the one that matches your formulation, curing requirements, and process — not the closest match to “one size fits all.”
We also provide product samples and formulation technical support to help you evaluate compatibility and tune your silicone system.
