The L-TEC® additive works by absorbing the laser energy and causing some very localised heating, for a very short time. This creates a dark mark obtained from the burning or charring on the surface or a light mark obtained when the laser causes the polymer to foam. Both light and dark marks are permanent and resistant to light, abrasion and chemicals. High contrast marks can be achieved quickly, and in virtually any colour and shade. Using our in-house laser, every formulation is fully tested and the right balance is achieved between the additive and colourants.
L-TEC® can also be incorporated into transparent polymers either as a natural or coloured tint, creating a dark mark.
In general, laser marking can be used to identify part numbers or product information to be permanently marked compared to a label or print which may peel off or wear off over time.
Ideal for: security applications, such as tags and seals, intricate decorative markings.
At Colloids we understand that developing a laser marking product is more complex than just colour, which itself is complex enough. That’s why our R&D team work on every laser enquiry to fully optimise each formulation, ensuring your product is the right colour, marks at the fastest speed with the highest contrast, and at the right cost.
