SiSiB® PCA-25 is a two-component platinum-catalyzed curing agent. It is a pasty platinum catalyst masterbatch used to vulcanize high-consistency rubber (HCR).
Post curing is not required.
No odor or flavor is produced (e.g. for food-contact applications)
No volatile peroxide by-products are released.
Meet ROHS, FDA, and LFGB requirements.
Transparent articles do not discolor.
Fast curing, resulting in shorter cycle times.
Improved tensile strength, tear strength, and resilience.
Component A | Colorless transparent gel |
Component B | Colorless transparent gel |
SiSiB® PCA-25 is a pasty platinum catalyst masterbatch used to vulcanize high-consistency rubber (HCR). This curing process ensures that there is no odor or taste, making it suitable for food contact applications. It also prevents the release of volatile peroxide by-products, ensures clear articles do not discolor during post-cure, provides a fast cure for shorter cycle times, and allows for easy demolding of cured products with a dry surface.
SiSiB® PCA-25A/B is available in 1Kg bottle and 20Kg pail.
In the unopened original container, SiSiB® PCA-25 has a shelf life of 12 months in a dry and cool place.
SiSiB® PCA-25A/B should be packaged separately in sealed bags in plastic cans and avoid direct sunlight.
SiSiB® PCA-25A will turn black when exposed to air for a long time. It is recommended to be refrigerated.
To prevent the volatilization of inhibitors in SiSiB® PCA-25B from causing dead glue during use, SiSiB® PCA-25B must be sealed and refrigerated.
