Apply with a Brush
PU140 polyurethane lacquer immaculately protects the strain gauge from humidity, moisture, condensation, salt air, tropical climates, oils, and greases through its excellent physical and chemical characteristics.
PU140 is an easy-to-apply, one-component covering material that ensures strain gauge protection. The polyurethane lacquer is applied to the measuring point with a brush integrated into the bottle’s screw cap and cures very quickly at room temperature.
PU140 immaculately protects the strain gauge from chemical and physical impacts. It is resistant to chemicals and solvents, such as ethanol, oil, or diesel (However, it is not resistant to most organic solvents and chlorinated hydrocarbons). PU140 protects the strain gauges from moisture, humidity, condensation, salty atmospheres, tropical climates, oils, and lubricants. After curing, PU140 also provides mechanical protection.
In many applications, the use of a combination of multiple covers is recommended to achieve optimal measuring point protection. With PU140, please note that the product must not be used in combination with NG140 covering material.
