Question- Can a light plastic bristle brushing with IPA be done to check adherence?

Answer- One Rule Of Thumb When It Comes To Using The CerMark. The Laser Mark Can Only Be As Durable As The Substrate It Is Applied To. I Can Suggest Testing To Determine The Best Setting.

Question- Where you can find a distributor in Mexico or you can make the purchase directly with you? 

Answer- We Have A Distributor In Mexico For Some Of Our Products And Some Can Be Purchased Directly, We Also Have A Representative In Costa Rica  

Question- My ink/paste has solidified. Can I re-liquify it?

Answer- Yes. You can re-liquify the ink by using small amounts of denatured alcohol or demineralized water. This process may take several hours or even days depending on how much material was in the container. Please remember that the more thinning agent you use, the lighter the pigment may become.

Question- am getting a brown rust color instead of a black mark. Are the CerMark laser marking materials bad?

Answer- No, the marking materials are fine. The browning or rusting occurs when you have applied too much thermal energy either due to slow speed or excess power. In this case, you have actually burnt the CerMark material. To fix this you should increase the marking speed or lower the laser power.

Question- I am marking glass with LMC products and get micro-fracturing. How can I prevent this from happening?

Answer-  Micro-fracturing occurs when the glass substrate is heated beyond its melting temperature and then rapidly cooled to room temperatures. These strong variations in temperature lead to local expansion and contraction and subsequently to micro-fracturing. There are two mechanisms of heating glass substrates: through conduction (ink heating the glass through thermal conduction), and through direct absorption. The latter is present mostly in CO2 lasers due to the absorption at CO2 lasers’ wavelength of operation. Consequently, solid-state lasers generate smoother marks. In both cases the micro-fracturing can often be minimized by lowering the power and the speed, thus creating gentle conditions for bonding – heating the ink just enough to bond to the surface and scanning slowly enough to deposit enough heat to bond.
