Premium Silicone Accelerator for Professional Applications

PlatSil® 71/73 Part X Accelerator is a platinum-compatible accelerator from Polytek Development Corp., specially developed for use with the entire PlatSil® 71- and 73-series silicone rubbers. By adding Part X, the pot life and demold time are significantly reduced, without compromising the final quality of the cured rubber.

Key Benefits

• Faster turnaround time: 1% addition reduces pot life to ~1/3 of the normal time; 2% to ~1/6.
• Flexible dosage: Precisely adjustable based on desired processing time and production rhythm.
• Broad applicability: Compatible with all PlatSil® 71- and 73-series products (Shore A10 to A60).
• No negative effect on final quality: Cured properties such as hardness and tear strength are maintained.
• Easy to process: Add to Part B before mixing with Part A; no adjustment of mixing ratio needed.

Typical Applications

• High-volume mold production where rapid demolding is required
• Prototyping and iterative design: multiple casting cycles per day
• SFX and prosthetics: rapid on-site production of silicone parts
• Industrial casting with tight delivery times
• Brush-on molds where rapid gelling per layer is desired
• Education and workshops: shorter waiting times between steps

Technical Characteristics

Add to Part B before mixing with Part A. Maximum dosage: 3% of the total mixed weight (A+B). Exceeding this may prevent the system from fully curing. Always test on a small scale before larger mixtures. Not suitable for use with PlatSil 73-20 (fast-curing system).

Produced by Polytek Development Corp. (Easton, PA, USA) – specialist in professional casting and molding materials for industry, art, and manufacturing.
