Clear urethane system for protecting circuit applications. The material is UL recognized (file E116296) and is commonly used in casting applications. It is a re-workable material.

Benefits

• Strong in-use product history
• No primers & excellent adhesion
• UL-recognized products
• Made with electronics-grade raw materials

Specifically designed for the encapsulation by casting of completed circuit board. The cured material meets the flammability requirements of UL 94, V-O at thickness of 0.070 in. and greater (UL File Number E116296) and provides long term circuit protection from -55ºC. to 125ºC.. The material bonds well to most metals, ceramics and plastics as well as to epoxy and paper phenolic circuit boards and, when necessary, allows repair by cutting away material in the area of the affected component, replacing the component and repotting. Some of the important properties of PNU 46201 are highlighted below:

* Low Shrinkage During Cure

* Excellent Flexibility At Low And High Temperature

* Excellent Flow Before And During Cure

* Water White Color And Smooth Surface After Cure

* Excellent Heat Resistance

* Room Temperature Repairability

* Excellent Adhesion To Most Substrates Without Primers

* Flame Retardant

* Excellent Humidity Resistance
