Epic S7310 - 2 Component Urethane Potting Compound

Timer encapsulated with polyurethane potting compound

Epic S7310 is a black two component urethane potting compound that features:

  1. Low viscosity
  2. 1:1 volumetric mix ratio
  3. Good resin/hardener compatibility
  4. Good durometer stability after exposure to elevated temperatures.

Based on thermally aging data, Epic S7310 will work in the -55C to 125C operating range, providing stress relief to sensitive surface mount components.

Epic S7351 - 2 Component-Room Temperature-Polybutadiene Based Polyurethane

Epic S7351 is a two-component, room temperature cure, polybutadiene based polyurethane potting compound. Epic S7351 was specifically formulated for electronic marine modules (EMM's) and is also an excellent candidate for electronic control modules (ECM's). Due to its low hardness and flexibility, S7351 will not exert stress on delicate surface mounted devices (SMD's) on printed circuit boards (PCB's) when exposed to extreme thermal cycling typical of marine and automotive electronics applications. This polyurethane potting compound is an excellent alternative to rigid systems that do not allow expansion and contraction of delicate components, causing failures. Also, due to the polybutadiene chemistry used in this formula, the product provides excellent high-temperature properties up to 125C and much-improved chemical resistance.

Epic S7475 - 2 Component Polyurethane Potting Compound

Control module potted with polyurethane encapsulant

Epic S7475 is a two-component polyurethane compound for potting electronic control modules (ECM’s) and a wide variety of electronic devices. The low mixed viscosity of the S7475 allows the material to flow into intricate areas under printed circuit boards and other tight tolerance areas. Another key property of this product is the 4:1 by volume mix ratio that allows the system to be very adaptable for meter mix and dispense processing. The very low hardness of S7475 in combination with the low Tg provides excellent flexibility, therefore allowing delicate surface mounted devices (SMD's) to expand and contract during thermal cycling and thermal shock. For applications that generate a great deal of heat, S7475 has shown extremely low weight loss at 130°C. S7475 is UL 94 V-0 recognized at 4.8 mm and is RoHS compliant.

Epic S7391-03 - 2 Component Polyurethane Gel Potting Compound

Epic S7391-03 is a two-component polyurethane gel potting compound designed for potting sensitive electrical components. Epic S7391-03 features a convenient 1:1 volumetric mix ratio as well as a very low mixed viscosity. Epic S7391-03 encapsulating urethane makes an excellent replacement for more expensive silicone potting materials.

Epic S7287 - 2 Component Polyurethane Potting Compound

Epic S7287 is a low cost, two-component polyurethane potting compound that is used in various electrical and electronic potting applications. Epic S7287 features a low viscosity which imparts good flowability for the ease of potting of parts. Epic S7287 is recommended for products that require the encapsulating compound to flow into intricate and tight tolerance designs.

Epic S7325 - Aromatic Urethane Potting Compound

Urethane potting compound for electronic circuitry

Epic S7325 is a low hardness aromatic urethane potting compound. S7325 has been designed with a convenient 1:1 by volume mix ratio. Epic S7325 is especially useful for applications requiring removal of the potting material for easy access to circuitry and components so that repair can be performed on expensive control modules. S7325 has a proven track record of performance in under the hood automotive applications.

Epic S7302 - Polyurethane Room Temperature Cure System

Epic S7302 is a tough, medium durometer, polyurethane potting and encapsulating material. S7302 is a room temperature cure system that may be accelerated by increased temperatures. S7302 is suitable for applications that require operating temperatures between 110 to 120C. Epic S7302 exhibits good adhesion to many types of thermoplastic cases, without the need for surface preparation. Epic S7302 is a great product for applications that will see vibration, thermal cycling and/or thermal shock.
