Tape, Cermark \ TherMark:
Certificate of Compliance: FERRO Inc. (‘seller”) warrants Cermark™ branded laser marking materials to be free from defects in materials and workmanship under normal use, and to have an effective shelf-life under normal use, for a period of six (6) months from the date of invoice. The shelf-life will be longer as long as the product is kept air tight and liquefied.
Recommended use: LMM6018.LF is a self-adhesive, paper-backed tape designed with similar pigments and formula as our liquid LMM products. It works well on most metal surfaces, offering a dry processing alternative to those not interested in or unable to work with wet products. It is also easier to use: the tape delivery system insures that a consistent layer of marking material is present on the substrate, entirely removing the variables of dilution and coat thickness.
Additionally, LMM6018.LF is TherMark’s recommended product for marking on clear or colored anodized metal. LMM6018.LF’s unique capability of marking on top of an anodized layer, rather than through it, is a major step forward in marking anodized surfaces. An important point in considering LMM6018.LF is the speed of marking which is significantly slower than for liquid/paste products. The main reason for this decrease in speed of marking is the thickness of the tape (both material and paper backing), which slows down the heat transfer process such that more time is required for the laser to fuse the ink to the substrate.
If you have a cycle time requirement per part, speed may be a relevant factor in deciding if LMM6018.LF is the right product for your application. For high volume, inline manufacturing jobs, TherMark recommends its LMM200 non-adhesive, PET-backed tape.
Important Note: This tape is only available from TherMark and TherMark authorized distributors. It is a different product than the LMM6018 (non-LF) tape sold by Ferro and their distributors. TherMark discontinued the old thicker tape with the release of this new and improved product. If you used that product without success in the past, we urge you to give this product a try.
Recommended substrates: LMM6018.LF is a fairly flexible product which is recommended for many metals, including those which are anodized. The following list is made up of substrates on which LMM6018.LF works well. This list is not exhaustive, however, so if your substrate does not appear on the list, this does not mean LMM6018.LF will not mark it.
| Stainless Steel | Chrome Plating |
| Stainless Steel - Bright Annealed | Nickel Plating |
| Galvanized Steel | Gold Plating |
| Brass | Titanium |
| Aluminum | Pewter |
| Anodized Aluminum |
Lasers that work: LMM6018.LF works well with both CO2 and solid state lasers. When using a solid state laser with LMM6018.LF you may wish to laser bond with pulsed operating mode, as CW operating mode requires a very slow marking speed.
Application method: LMM6018.LF is a self-adhesive, paper-backed tape. Please make sure that the surface to be marked is free and clear of oils, cleaning agent films and dust.
- Tape application: To apply, unroll a sufficient amount of tape to cover the surface area to be marked and stick the black adhesive side down carefully. It is important the tape have uniform contact with the substrate surface otherwise some areas may not bond properly during laser marking. Care should be taken to remove any air bubbles from under the tape: smoothing down gently with fingers should be adequate to remove air bubbles. If you wish to mark on a surface that is highly irregular with too many bumps or crevices, self-adhesive tape may not be appropriate because uniform tape to substrate contact may be impossible.
Drying time & methods: LMM6018.LF does not need to dry and can be laser marked immediately after application.
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. To read more detailed information on laser settings please see below.
Product Appearance: LMM6018.LF self-adhesive, paper-backed tape comes on a plastic core. The adhesive side containing the laser marking material is black; the paper backing is a waxy white.
Shipping options: LMM6018.LF tape is a non-hazardous product and can be shipped via ground or air with no additional charges.
Product storage: LMM6018.LF should be stored between 40ºF (5ºC) and 95ºF (35ºC) in a dark, dry place. If you plan to leave LMM6018.LF unused for longer than a week, the roll should be stored in a Ziploc bag or wrapped in plastic wrap to prevent the tape from drying out due to long-term air exposure.
Disposal: LMM6018.LF tape is an environmentally friendly, non-hazardous product. Excess tape material can be easily and safely disposed of by discarding in the regular trash.

Testing & Power Grids: The process of establishing the correct laser settings to make TherMark laser marking materials successfully bond can be time consuming because of the number of variables involved. To expedite this process, it is possible to quickly determine the optimum settings using what is known as a “power grid”. In the laser bonding process, the two most important variables are the laser power and the speed with which the beam passes over the material. A power grid is a graphic file constructed to apply different speeds and powers to different parts of the image; this allows the user to test multiple settings with a single pass of the laser, greatly reducing the time taken to find the best setting. In the picture below, each square in the grid has a different combination of power and speed settings as illustrated in the axes. The Y axis decreases power in increments of 10% from top to bottom (100% power at the top, 30% power at the bottom), while the X axis increases speed in increments of 10% from left to right (10% speed at the left, 100% speed at the right). As you can see, optimal marking will only take place when the right amount of energy is transferred by the laser. Section (1) shows that when power is too low and speed is too high there is not enough energy to create a bond. Likewise, section (2) shows that too much power at a low speed causes the material to be removed, possibly causing damage to the substrate surface. The ideal “process window” lies in section (3) of the photo. Any of these settings will produce excellent marks on the substrate. Picking a setting in the middle will allow maximum latitude for variability between machines and material. In other cases such as a production environment, the fastest speed possible to create a mark may be preferred. In summary, when using a TherMark product for the first time on a new substrate, it is advisable to run a power grid on a scrap part in order to determine the optimal settings for your laser/substrate/material/coating combination. |
