Description
  • Catalyst for mold-making rubbers. Dow SILASTIC RTV-3010-S Catalyst is used with RTV-3 series silicone mold-making rubbers, such as SILASTIC RTV-3110 Base, to cure them into firm, flexible silicone. LabPro notes it is a reformulated, REACH-compliant version of the S Catalyst, and it is supplied as catalyst only.
  • Blue for process control. The catalyst is blue, and its color helps users visually confirm that the catalyst has been thoroughly mixed into the silicone base. Once fully blended, the tint does not change the final appearance of the cured product, giving a simple, reliable mixing check on the shop floor.
  • Performance and versatility. Used with a compatible RTV-3 base, the system enables precise molding, adjustable cure times, and detailed reproduction across a wide service temperature range. Beyond mold making of patterns and shapes without deep undercuts, it can also be used in electronic potting and encapsulating applications.
  • Usage notes. Dow's mold-making data indicates RTV-3010-S is used at a 10:1 base-to-catalyst ratio with bases like RTV-3110. Note that RTV-3010-S (and RTV-3000 F) should not be used when molding polyesters because the polyester can inhibit cure; Dow recommends a different catalyst for polyester molds. Review the product and Safety Data Sheets before use.

FAQs

What is RTV-3010-S Catalyst used with?

It is the catalyst for Dow's RTV-3 series silicone mold-making rubbers, such as SILASTIC RTV-3110 Base. Mixed into a compatible base, it drives the cure to a firm, flexible silicone. It is supplied as catalyst only, so a separately purchased base is required to use it.

Why is the catalyst blue?

The blue tint lets users visually confirm the catalyst has been thoroughly mixed into the silicone base, which helps ensure a uniform, reliable cure. Once fully blended into the base at the correct ratio, the tint does not change the final appearance of the cured mold or part.

What mix ratio should I use?

Dow's mold-making data indicates RTV-3010-S is used at a 10:1 base-to-catalyst ratio with bases like RTV-3110. Accurate proportioning matters, since wide departures from the recommended ratio can alter cured properties. Always confirm the ratio for your specific base in its technical data sheet.

Are there materials it should not be used with?

Yes. Dow advises against using RTV-3010-S (or RTV-3000 F) when molding polyesters, because the polyester can inhibit the cure. For polyester molds, Dow recommends a different catalyst. When in doubt, test a small area for proper cure before committing to a full mold.

Is this catalyst REACH compliant?

According to the LabPro description, RTV-3010-S is a reformulated, REACH-compliant version of the original S Catalyst. For regulatory documentation specific to your region or program, confirm the current compliance status and request the appropriate paperwork, and review the Safety Data Sheet before handling.
