Momentive Performance Materials, a global provider of silicones and advanced materials, has introduced an innovative polymer and catalyst technology that enable the use of SilForce UV curable release coating products for odor sensitive applications.
Carlos H. Flores, Momentive Performance Materials’ Global Marketing Director, Release Coatings and PSAs, stated that the novel system can help their customers to differentiate Momentive’s products in the market. The SilForce coating is an ideal solution for coaters, when odor-free performance is required for disposable diaper tapes and various other personal care products. In addition, the product helps to save energy costs as it requires a low-temperature cure process, noted Flores.
SilForce UV9880C, an odor-free catalyst, is developed for application with the company’s SilForce line of low odor UV curable polymers. It does not contain organic solvents and is compatible with medium pressure mercury vapor UV lamps. Other features of SilForce UV9880C include cationic type photocure; fast photocure in ambient atmosphere; high reactivity; and low temperature cure usually required for thermally sensitive film and paper substrates.
Momentive has released two silicone release polymers, SilForce UV9815 and SilForce UV9800, for use with UV9880C photoinitiator. The odor-free polymers offer several benefits, including stable release from a broad range of adhesives; highly crosslinked coating with minimal silicone transfer; a rating of 1 on a 1 (none or slight) to 5 (strong) scale utilized in independent odor panel testing; and extended catalyzed bath life while stored in dark, cool conditions.
