Dry barrel polishing is an essential step in the manufacture of cellulose acetate frames.
For over 60 years, TCN has been designing and manufacturing a complete range of polishing compounds for eyewear professionals.
This process involves several successive stages: sanding, semi-sanding, polishing, and, optionally, buffing. Each of these phases produces a uniform, shiny finish while respecting the delicate curves and edges of the frames.
Our polishing compounds are constantly evolving to meet user expectations and anticipate regulatory requirements. Several formulations are available for each stage: a traditional version and a “green” version, which is completely free of substances that are harmful to users and the environment.
All of our products are manufactured in our workshops, close to the eyewear manufacturers.
We also offer all the ancillary products required for the process: detergents, wooden pegs, and process oils.
Cellulose acetate, prized for its lightness, strength, and malleability, is the material of choice for designers of high-end eyewear.
Our TACC concentrated dyes enable simple, rapid coloring of parts made from cellulose acetate, cellulose propionate, or bio-derived materials.
The colors obtained retain their brightness over time, without migration or discoloration.
Available in solid colors or gradients, the range allows you to create an infinite number of different shades, customize frames on demand, or reinvent previous season’s collections.
We formulate epoxy resins designed to embellish cellulose acetate eyewear temples. Our epoxy resins are used in eyewear for the inclusion of metallic logos. This step is carried out before your barrel polishing.
We offer two ranges for coloring epoxy resins:
Hot and cold adhesives enable the assembly of different cellulose acetate parts of eyewear frames for increasingly creative handmade collections.
Color customization of TR90 injected eyewear frames is possible with our universal coloring range, GTC.
Eyewear frames made from additive manufacturing can be dyed with our high-performance GTD range.
