Coating of glass work

Depending on the final application of the glasswork, we can treat the glass surface in several ways

  • Coating: application of an elastic layer made of TEFLON, PVC, or another material. In case of breakage, this layer will protect the user against glass splinters or the content. We can offer several coatings depending on the temperature of use, the chemical resistance or other requirements.
  • Non-actinic: application of a thermal layer in the form of a brown and see-through varnish. This type of covering protects the content from radiations, that can cause photochemical reactions.
  • Silver layer: application of an opaque and silver solution on the double wall of the glasswork. This provides a better thermal (warm or cold) and optical isolation.


Glass cylinders

If required, we can cover the glass work with a TEFLON COATING.
The COATING that we use has many advantages:
- The glass work obtains an excellent mechanical resistance. The cover is placed in such a manner that it fits perfectly to the glass and keeps its elastic qualities. Therefore in case of damage the dissipation of the content is avoided. In that way the content can be raptured and the security of the user is guaranteed.
- The COATING has a good heat resistance. The maximal use temperature is 260°C.
- The cover is transparent, therefore the glass work conserves its principal feature.
- The surface of the COATING is completely dry. In consequence dust does not attach itself.
- Each possible glass work can be covered with this COATING, regardless of its shape.

On the photo you can see two cylinders of 2000 ml and 3000 ml, graduated and covered in and with a layer of our COATING TEFLON (PTFE).

Non-actinic application on a double walled reactor

Upon request of the client, we have manufactured a double-walled reactor with a DN200 lid. In order for the reactor to resist external radiation, we treated the glasswork with a non-actinic, brown and see-through layer.

Thermo flasks

These Thermo flasks are a nice example of a covering of the surface of glasswork. We have treated the double wall with an opaque silver layer and we created afterwards a vacuum. This provides a better thermal (warm or cold) isolation. On the picture you can see the assembly of this glasswork in a protective packaging to facilitate the transport.
