Silicone Rubber Condensation and Addition Cure Explained
Addition cure silicones use a platinum-based catalyst (usually 10%) while condensation cure silicones need a tin-based catalyst (usually 5%). The platinum catalyst used in addition cure silicones is susceptible to some chemicals like nitrogen, sulphur, phosphorus, sulphur vulcanized rubbers and condensation cure silicone rubbers.Get Price

Condensation-cure systems comprising at least one silanol-functional polyorganosiloxane and a platinum catalyst are described. The platinum catalysts include Pt(0) complexes, a Pt(II) complexes, and a Pt(IV) complexes. Condensation-cure systems comprisingGet Price
Silicone rubber may be cured by a platinum-catalyzed cure system, a condensation cure system, a peroxide cure system, or an oxime cure system. For the platinum-catalyzed cure system, the curing process can be accelerated by adding heat or pressure.Get Price
Silicone Rubber Platinum-Based Catalysts | SIMTEC
Description of the Platinum Chemical Reaction that Forms Silicone Rubber The silicone industry extensively uses the platinum-catalysed hydrosilation reaction in which a silicon-hydrogen (Si-H) bond is added across an unsaturated carbon-carbon double bond (C=C) of an olefin, resulting in the formation of a silicon-carbon (Si-C) bond.Get Price

What are the major differences between tin-cure (condensation cure) and platinum-cure (addition cure) silicone mold making rubbers?
Silicone rubber is sensitive to sulfur that can be found on different surfaces and are present in some types of modeling clay. Platinum-cure silicone rubbers are critically sensitive to sulfur and will not cure under any circumstances when exposed. Tin-cure siliconeGet Price
Why your silicone is not curing: Inhibition and poisoning of silicones - G A Lindberg ChemTech Blogg
A silicone system that uses a platinum-based catalyst (a so-called addition curing silicone) are sensitive to certain compounds that prevent curing reactions from taking place. If your silicone is not curing, then you should look for possible inhibitors or poisons that could prevent it.Get Price
Identifying Chemicals that Cause Inhibition in Platinum Silicones | Quantum Silicones
The platinum can become deactivated by coming in contact with certain chemical species. Once the catalyst is deactivated or poisoned, the affected area of silicone may never cure to the proper state of cure – meaning the inhibited area may stay runny, sticky, or fluid.Get Price
What is silicone rubber? - Smooth-On, Inc.
Tin catalyst silicones will shrink somewhat and do not have as long of a library life compared to platinum-cure silicone or urethane rubber. Tin Cure Silicone: Also called condensation-cure silicone, these are high-tear silicone rubbers that are known as the “work horse” of the industry because of their performance and economy.Get Price
Silicone Technologies Uncured Silicone Sealants Adhesives Gels Coatings Cure Systems
Silicone elastomer can be crosslinked ("cured" or "vulcanized") into solid forms through a variety of cure systems. The most common curing systems are: 1) addition cure chemistry (platinum catalyst) which does not require moisture or open air, and 2) condensation cure (tin catalyst) chemistry which requires airborne moisture.Get Price
