Urethane Potting Material

They offer a unique blend of properties for structural bonding coating sealing and potting applications.
Urethane potting material. This potting compound is formulated for use in sensitive applications such as manufacturing semiconductors. Epoxyset urethane potting materials have low cte rates ensuring flexibility at even extremely low temperatures. They have been formulated in convenient 2 1 mix ratios and provide strong protection from moisture sea water solvents and mechanical stress. Mg chemicals offers polyurethane potting compounds as a cost effective alternative to other chemistries for protecting printed circuit boards and electronic devices.
These materials are especially suitable where low temperature flexibility is required. Following is a table of generic uncured and cured properties for epoxy urethane and silicone potting compounds. Polyurethane covers a broad range of materials and can replicate virtually any type of hardness for products including gel glass thermoplastics rubber and led. The thermoset material is usually an epoxy a urethane or a silicone potting material.
The main constituents resin and hardener are already mixed together with no additional mixing required. It is ideal for electronic applications surface mount technology and when thermal cycling resistance is a requirement. 4 major constituents of potting material 1 k and 2 k potting one component 1k potting. Urethane withstands a wide range of temperatures and is the best choice for cold temperature applications.
The best way to remove an electronic urethane potting compound is by using a solvent which will slowly soften the potting compound and picking away at it with a sharp tool such as a putty knife or file. The other silicone chemistry is the condensation type which uses tin salts as catalysts. Motor potting is the process of filling in all the air gaps around the coils in a motor usually the stator but sometimes also the rotor with some type of thermoset material. These formulations usually offer better adhesion but are not good for potting very large masses due to unevenness of cure.
S7475 2 component polyurethane compound epic s7475 is a two component polyurethane compound for potting electronic control modules ecm s and a wide variety of electronic devices. Many urethane products epoxyset offers use renewable raw materials making it less harmful to the end user. Encase electronic assemblies in a layer of material for protection from dust moisture chemicals mechanical shock and vibration. 1k potting materials are therefore ready for use.
The low mixed viscosity of the s7475 formula allows the material to flow into intricate areas under printed circuit boards and other tight tolerance areas. High quality microelectronics potting and encapsulating formulations and products. Urethane modified compounds were developed by master bond to solve design manufacturing and specialty applications across a broad range of industries.
