Platinum Cure is Emerging as the Alternative to Peroxide Cure

For decades, the industry standard for cured silicone elastomers has been peroxide curing.platinum curing However, a new method of cure called “platinum curing” has emerged as an improved process that yields higher-quality, stronger products with better resistance to heat and water. To learn more about this innovative technology, here are some of the important things to know about platinum curing.

While peroxide-cured silicones have been the industry standard for years, platinum-cured silicone elastomers are increasingly becoming the preferred choice in many applications.platinum curing This is due to a number of factors, including their superior mechanical properties and the fact that they produce significantly less volatile byproducts than peroxide-cured materials. In addition, platinum-cured silicones can be formulated to cure at room temperature and without the use of heat – making them more convenient for many users.

In the production of platinum-cured silicone rubber, a small amount of pure platinum is added to the mixture to serve as a catalyst.platinum curing This initiates a chemical reaction between the si-H groups of the crosslinkers and the vinyl functional groups in the base silicone polymer to create a hardened elastomer.

The process of platinum curing is much faster than peroxide curing, meaning that the material can be molded and used sooner. This is a huge benefit for those in the manufacturing of industrial silicone rubber parts and gaskets, as it reduces production times and helps increase productivity. Another factor that contributes to the popularity of platinum cured silicone is its high tolerance for both temperature and moisture. This makes it suitable for a wide range of environments and applications.

Platinum cured silicone also has lower shrinkage rates than tin-catalyzed systems, and is less sensitive to inhibition from materials that poison the catalyst. However, it is still essential to avoid exposure to organotin, organosulfur, and some amines if using a platinum-cured silicone.

This type of silicone is ideal for use in manufacturing processes that require a quick reaction time. It is also a great choice for projects that require high adhesion and good weathering, such as in the aerospace and automotive industries. It is also popular in fluid-handling applications for its durability and strength.

When working with platinum-cured silicone, it is essential to follow all of the product instructions. The most common precautions are to wear latex gloves and not mix it with any solvents or other chemicals. The platinum catalyst in the product can be permanently damaged by these contaminants, so it is important to avoid them as much as possible. Primasil technicians are always available to provide guidance as to what situations to avoid when working with these materials.
