Chemical Resistance of HIS Monitors and Touchscreens

Other than stainless steel, there are four separate polymeric materials that are exposed to the environment on the front of our panel mount monitors. The chemical resistance of each is outlined below.

Resistive Touchscreen

The surface of the resistive touchscreen is made of polyester and is resistant to the following chemicals when exposed for a period of one hour at a temperature of 70 deg F (21 deg C):

• Industrial Chemicals - Acetone, Methylene chloride, Methyl ethyl ketone, Isopropyl alcohol, Hexane, Turpentine, Mineral spirits, Unleaded Gasoline, Diesel Fuel, Motor Oil, Transmission Fluid, Antifreeze, Automotive Hydraulic Fluid, Skydrol.
• Food Service Chemicals - Ammonia based glass cleaner, Laundry Detergents, Cleaners (Fantastic, Formula 409, Joy, etc.), Vinegar, Coffee, Tea, Grease, Cooking Oil, Salt.

Panel Sealing Gasket

The panel sealing gasket material is a polyether / polyester urethane blend. It is unaffected by mild inorganic acids and bases. It shows modest swelling with oils, greases and other linear hydrocarbons. Strongly polar solvents will greatly swell the material. In most cases, physical properties recover to a great extent as the solvents evaporate.

More specifically, the gasket material is resistant to the following chemicals: Industrial Chemicals Acetone, Methanol, Kerosene, cutting fluids, hydraulic oil, Isopropyl alcohol, mineral spirits, motor oil. Where the chemical resistance of the gasket is inadequate, it is possible to protect the gasket with a bead of Polysulfide sealant.

Protective Tempered Glass Window (non touchscreen units)

The anti-reflective coating on the tempered glass for non-touch monitors is resistant to the following chemicals: Industrial Chemicals Acetone, Ethyl Alcohol, Isopropyl Alcohol(50%), trichloroethylene.
