Shin-Etsu X-93-405 Cure Accelerator, 1 Kg

Description

X-93-405 accelerator is a Shin-Etsu cure accelerator for addition-cure silicone materials, supplied here in a 1 Kg can for shops that need tighter control over molding, casting, repair, or prototype schedules. It is used when a compatible addition-cure silicone needs a shorter cure window, with the tradeoff that working time is shortened as cure speed increases. For compatible silicone systems and related casting supplies, see Chemical Concepts’ encapsulants and potting compounds category.

X-93-405 accelerator For Addition-Cure Silicone Work

This product is intended for addition-cure materials, not condensation-cure silicone systems. Shin-Etsu literature identifies X-93-405 as a cure accelerator for addition-cure products, and Chemical Concepts lists the package as a 1 Kg can with translucent appearance. Use it where the process can accept a shorter open window in exchange for faster set or cure timing. That makes it useful for trained silicone users who already know their base resin, catalyst ratio, temperature, and required pot life.

X-93-405 accelerator Handling Notes

Because accelerators affect both cure time and workable time, measure carefully and run a small trial before scaling into production. Too much accelerator can make a mix tighten faster than expected, especially in warmer work areas or thicker sections. Keep batch size, room temperature, mold temperature, and mixing method consistent when comparing results. The product is best treated as a process control additive, not a general-purpose adhesive or sealant.

Where It Fits In Production

X-93-405 is a practical choice for silicone moldmaking, casting support, and repair workflows where an addition-cure system is already qualified and the schedule needs adjustment. It can help reduce wait time between pours, demolding steps, or downstream handling, but only when the base system allows the change. For additional product-family context, Shin-Etsu publishes silicone moldmaking guidance through Shin-Etsu Silicone.

Buying And Support

Order this 1 Kg can when the application calls for a Shin-Etsu addition-cure accelerator and your team has confirmed compatibility with the silicone system in use.
