OMEGALAQ ® Temperature Indicating Liquids
GENERAL DESCRIPTION: OMEGALAQ ® Temperature Indicating Liquid (LAQ) OMEGAMARKER ® consist of a temperature
melt material in a liquid form. They are made from the same material used in the OMEGAMARKER ® temperature indicating
products this time in a lacquer suspension. Lacquer serves as a transport function only. The OMEGALAQ ® temperature
indicating liquids are used to tell temperatures on surfaces such as polished metal, glass, plastics, rubber, fabrics or
electronic components. They can be used for making large marks which can be viewed at a distance. These temperature
indicating liquids are widely used for monitoring critical temperatures in the electronics field, such as preheat temperatures for
wave soldering. Other applications include dielectric heatsealing, postforming plastic laminate, and annealing polished metal
surfaces.
The OMEGALAQ ® liquids (LAQ) have a time response on the order of milliseconds (0.001 sec.). They are available in many
temperature ratings. The OMEGALAQ ® liquids have an accuracy of ±1% of the rated temperature.
DIRECTIONS FOR USE:
LIQUID TYPE: Shake and/or stir jar contents well just prior to use. Apply a thin coating by using a brush to the surface being
tested before the object being tested is brought up to temperature. It dries almost instantly to a dull opaque finish. When its
specific temperature is reached, the opaque finish liquifies abruptly. The melted material does not revert to its original opaque
appearance but remains glossy and transparent upon cooling.
OMEGALAQ ® liquids can be diluted to any desired consistency without changing its melting point. The thinner the coating
used, the quicker the reaction time will be when the rated temperature has been reached. When thinning, use OMEGA’s
OMEGALAQ
® Green Label Thinner only.
REMOVAL AND CLEANING: For lacquers with temperature ratings of 650°F or below, the unheated mark can be removed
with alcohol or water. For ratings above 650°F, use water only. If the mark has been heated well above the rated temperature
and has become charred, an abrasive procedure may be required for removal.
OMEGALAQ ® LIQUIDS IN A VACUUM: The following rated OMEGALAQ ® liquids are the best candidates for high vacuum
work. They show relatively little loss of substance in a vacuum at the temperature level of their respective melting points,
compared to other OMEGALAQ
® products of nearby temperatures.
TEMPERATURES (°F)
175 200 475 1150 1500 1800 2000
225 488 1200 1600 1900
325 500 1250 1700
700 1300
750
Bear in mind that prolonged heating in a high vacuum, or heating to a temperature well above the melting point, some
sublimation or evaporation is to be expected. Thus, the user needs to check the suitability of OMEGALAQ
® products under
the temperature/pressure/time regime planned. OMEGA assumes no responsibility for the use of OMEGALAQ ® products
under vacuum conditions.
SHELF LIFE: Temperature indicating Products have a limited shelf life. By verifying the melting point of the lacquers at six-
month intervals, the effective shelf life of these products may be extended indefinitely. If they have dried out, OMEGALAQ
®
products may be liquefied by using the Green Label Thinner. See directions for use and warranty for further information.
