Quick Overview

LMM-14 is one of two general purpose laser marking compounds recommended for creating a black mark on most metals,specifically specialty metals. The combination of its flexible process window and wide range of applicable substrates makes LMM-14 very easy to use. In general, if you are looking for one laser marking product to keep on your shelf, we recommend LMM-14. LMM-14 dries quickly as a light-gray powder coat and is extremely easy to wash after laser marking. This coat should not be extensively handled prior to laser marking, and should be marked shortly after application.

Recommended substrates:
LMM-14 is a flexible metal marking product recommended for most standard metals. The following provides a list of substrates on which LMM-14 works well. This list is not exhaustive, however, so if your substrate does not appear on this list, please call or email LJS for suggestions and recommendations for your laser application.

Lasers that work:
LMM-14 works equally well with CO2 and solid state lasers.


Dilution Recomendation:
LMM-14 requires different dilution ratios depending on your desired application.

  • Air Brush Application: Ratio of 1:1 (1 part in volume of LMM-14, 1 part in volume of denatured alcohol) is recommended. Please refer to your air brush manual for information about material thickness for your model type.
  • Foam Brush (hand) Application: Ratio of 2:1 (2 parts in volume of LMM-14, 1 part in volume of denatured alcohol) is recommended.


Application Methods:
Please make sure the marking surface is free and clear of oils, cleaning agent films, dust, and lacquer coating before applying TherMark™ to ensure best marking results.

  • Aerosol Application: Shake the aerosol can thoroughly before use to achieve a homogenous suspension of marking material inside the can. When applying LMM-14 from an aerosol can, the resulting coating of LMM-14 should be about 1 mil thick (~25 μm). Spray uniformly at a 10” distance from the surface and move the nozzle from one side to the other covering the whole substrate area. Start spraying away from the area to be marked and move towards the opposite side and past the target area. Over-spraying before and after the target area allows constant velocity of movement and will help provide an even coating on the substrate. Make sure the bare metal is not visible underneath. If necessary spray one or two more times. In general 2-3 strokes are enough to generate the desired coating.
  • Air Brush Application: When airbrushing use the above mentioned procedure for aerosol application.
  • Foam Brush (hand) Application: When hand applying LMM-14 the resulting coating of LMM-14 should be 1-2 mils thick (~25-50 μm). Use about a 1” wide foam brush and soak less than ¼” of the brush with LMM-14. Increased brush soaking is not necessary, otherwise the ink may splash and result in an uneven coat thickness. Apply with smooth, even strokes. Note: Aerosol and air brush application are both preferred over foam brush applications. Even coating of laser marking material can be challenging to achieve for optimal marks when using a foam brush. We only recommend foam brush application if you do not have an air brush or are coating a small surface area.


Drying Time & Methods:
If left to air dry, LMM-14 is normally fully dry within about two and a half minutes. If air drying takes too long, however, a hair drier or forced air heater may be used to speed up the process. LMM-14 can be fully dried with an average household hair dryer in 5-7 seconds.


Laser Settings:
Power and speed are the two most important variables to control when using TherMark laser marking materials with any laser, but there are other relevant variables depending on which laser you are using, such as length of lens, PPI, DPI, frequency, or hatch spacing.


Product Appearance:
LMM-14 liquid will often separate and needs to be well-stirred or shaken prior to use. The dense, heavy part of the marking material containing frit and pigment is silver/gray in color, while the thin, light part of the marking material containing mainly thinning agent may be yellowish green or greenish blue.

Once applied to the substrate and dry, LMM-14 will be a light-gray powder coating.


Shipping Options:

  • LMM-14 aerosol is considered by the US Department of Transportation (DOT) to be “ORM-D” or “Consumer Commodity”. This product may be shipped via ground or air. TherMark does not add any additional charges for ground shipping of this product, but LMM-14 aerosol is subject to an additional $40 hazardous materials packing fee if shipped via air. This is due to regulations around the shipping of pressurized cans on airplanes.
  • Overnight Shipping of LMM-14 is not available!
  • LJS Ships all Metal Marking Compound (LMM-6000 and LMM-14) via FedEx Ground unless otherwise indicated.


Product Storage:
All LMM-14 products should be stored between 40ºF (5ºC) and 95ºF (35ºC) in a dark, dry place. Aerosol cans should be stored on their side rather than their bottom, as the LMM-14 material can settle and clump together inside the can. Side storage allows for even dispersion upon shaking.


Disposal:

LMM-14 is a water-based material and is environmentally safe and non-hazardous. After laser bonding, any excess, un-bonded material can be washed off the substrate and down the drain into your normal water/sewer waste area.Note: Using hot water and rubbing the substrate surface with rubber or latex gloves works the best with regard to cleaning parts/materials after laser processing.

Unused aerosol cans that are still pressurized should be de-pressurized in a well-ventilated area (the propellants should be completely expelled from the can) and disposed of in your regular trash and solid waste area.

Unused containers of liquid ink/paste can be safely disposed of in your regular trash and solid waste area.
