Scripting
A process in which a clear doming material (urethane or epoxy) is applied to labels, decals or nameplates that feature scripted lettering, graphics or symbols. XYZ automation is often used to control the deposition path of the doming material.
Shelf Life
The amount of time a material may remain useable in its original containers.
Shore Hardness
The reading of a material's hardness on a durometer similar to the Shore A durometer. The scale of 0-100 is used on rigid and semi-rigid materials. Consists of a pin point depression into the material. Both the Shore A and Shore D instruments are made by the Shore Instrument Manufacturing Company, Inc., Jamaica, NY.
Silicone
Polymeric materials composed of molecules of silicon and oxygen.
Solvent
A liquid substance which dissolves other substances.
Specific Gravity
The ratio of the weight of any volume of a mass or substance to the weight of an equal volume of water at given temperature. The specific gravity of a substance times the density of water equals the density of the substance.
Substrate
Any material on whose surface an adhesive is spread for bonding or coating.
Surface Resistivity
The resistance of a material to the flow of electric current over its surface. Measured in ohms/centimeter

Tensile Shear Strength
See Lap Shear Strength.
Tensile Strength
The ultimate pulling force required to break a material. Measured in pounds/sq. Inch or megapascals.
Tg
See Glass transition temperature
Thermal Conductivity
A measure of a material's ability to conduct heat. Measured in BTU-inch/hours-square foot/°F or calorie-centimeters/second-square centimeters/°C.
Thermal Expansion
See Coefficient of Linear Thermal Expansion.
Thermoplastic
A plastic which will repeatedly flow under the application of heat and pressure.
Thermoset
A plastic material that is capable of being changed into a non-melting or insoluble product by heat or chemical means.
Thixotropic
Describes materials that will not flow unless agitated or forced through an orifice. Shear thinning.
Thixotropy
False body. The property of a paste or fluid to thicken or set up to a paste or a semi-gel when allowed to stand. Agitation breaks it down but further standing will again permit a viscosity rise.

Urethane
A polymeric material that is formed by the use of an Isocyanate base chemical.
