The Silicone Conundrum Part II: “Low Outgassing” Silicones

Silicones have many desirable properties and as a result are incorporated into a wide range of products. However, they present unique problems that result from their propensity to outgas resulting in residue formation at unexpected places. Hence, the silicone conundrum—when to use these materials and when to beware of potential pitfalls. In this article, an outgassing mechanism unique to “low outgassing” silicones is discussed. Examples are given where this has led to failures and remediation steps are highlighted.
