| Epic S7351 is a two component, room temperature cure, polybutadiene based polyurethane. S7351 was specifically formulated for potting electronic marine modules (EMM) and is also an excellent candidate for potting electronic control modules (ECM). Due to its low hardness and flexibility, S7351 will not exert stress on delicate surface mounted devices (SMD) on printed circuit boards (PCB) when exposed to extreme thermal cycling typical of marine and automotive electronics applications. S7351 is an excellent alternative to rigid systems that cause failures by not allowing expansion and contraction of delicate components. S7351 provides excellent high temperature properties up to 125C and good chemical resistance. |
