MIL-HDBK-1110
SSPC.
Steel Structures Painting Council.
STEL.
Short-term exposure limit.
TCLP.
Toxic characteristic leaching procedure.
Thermoplastic. Paint softened by heat or solvent (type of one-
component coating made up of high molecular resins which dry/cure
by solvent evaporation, e.g., vinyls).
Thermosetting. Paint that cures by undergoing a chemical
reaction leading to a relatively insoluble material (e.g.,
epoxies, polyurethanes).
Thinner. Reducer; solvent added to reduce paint viscosity for
easier application.
Thixotropic. Paint of gel consistency in the can that becomes a
liquid paint when stirred or brushed but becomes a gel again upon
standing.
Through Drying. Curing of paint film through the entire
thickness as opposed to curing only on the surface.
Tiecoat. Thin coat applied to a cured paint to enhance the
bonding of a topcoat.
TLV.
Threshold limit value.
Tooth.
Profile; mechanical anchorage; surface roughness.
Top Coat.
Finish coat.
Triggering.
Intermittent squeezing and releasing of spray gun
trigger.
TWA.
Time weighted average.
Ultraviolet Radiation. Portion of sunlight having a shorter
wavelength than visible light.
Undercutting. Blistering and/or peeling of paint from underfilm
corrosion in areas of a paint defect.
Urethane Resins.
A particular group of film formers.
Useful Life.
The length of time a coating is expected to remain
in service.
