Abstract: Regulatory considerations are key when determining material selection for product formulations. The list of regulations impacting the electronics industry includes REACH, RoHS, OSHA, and DOT, as well as regionspecific requirements such as California Proposition 65. Electronics manufacturers need a proactive approach to manage these regulations. In this paper, we will share an overview of relevant regulations, approaches for managing information, and some of ResinLab’s work to formulate or reformulate products with exceptional performance that also meet these requirements.

One example of a success story within ResinLab is the identification of a substitute for alkylphenols. Alkylphenols such as nonylphenol are commonly used as accelerating agents in epoxy formulations. However, this class of chemicals is classified as an endocrine disruptor. Nonylphenol and ethoxylated nonylphenol are listed as REACH Substances of Very High Concern (SVHC). For existing formulas, it was critical to identify a substitute for nonylphenol that generated similar performance, both in liquid form and after the material had cured and hardened. Equally critical was that the substitute’s health, safety, and toxicology profile be outside of the ‘class’ of alkylphenols so that the substitute would not land on the same set of regulatory lists. ResinLab has identified such a substitute. Substitutes were also identified for diundecylphthalate and bisphenol A monomer. Data will be shared demonstrating the match in performance with this substitute.
