B2-Coating

A innovative coating for elastomers

B2-Coating, developed by Daikyo Seiko, Ltd., is a cross-linked mixture of high- and low-molecular weight silicone oils that are cured through the application of UV rays and heat. Because it is a spray-on coating applied to molded closures before the trimming process, B2-Coating can be applied at various levels on the bottom and top of closures.

Overview

Benefits of using B2-Coating on an elastomer product include:

A reduction in the amount of extracted silicone oil, particularly at higher pH levels
Lower levels of particle compared to conventional silicone oil

With the growth in protein-based and large molecule drug products, silicone oil sensitivities are increasingly common. B2-Coating is an alternative to conventional silicone oil for these applications and may reduce the amount of protein aggregation due to silicone.
