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.

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.
