Coating Glassware

We need more info like what will the glass be used for? How big is the object to be coated? Does the coating have to be heat proof, acid proof, alkali resistant?

The more you give the better the answers can be.

There are plastics that might do the job if we knew more about it.

Glass breaks and is hard and brittle. Any covering that would reduce this has to be softer, so the impact will not propagate into the glass. This means clear ABS plastuc etc. These things will work, but up to a point, then they are penetrated and the shattering impact hits the glass.

There is a new armored material, based on alumina and nitride (aluminium oxynitride). This is made and powdered to below 1/4 wave of light and a small % of inclusions are added, also below 1/4 wave of light in size. The powder is then sintered at high temperature under a vacuum between flats. The high temperature and vaacuum and pressure compress the material into a clear solid, with no crack propagation method. Any crack soon hits an inclusion and stops. Currently used as strike plates (first to get hit by a bullet) backed up by lesser(but cheaper) armor plate glass laminate, it it the current best material.

Best would be 1.5" of this stuff made up of 6-8 plates with ABS in between, but each one costs $15-20 per square inch, so 8 =~$120 per square inch, 1 square foot thus costs $18,000 = too much. But the first hoit stroke plate backed up be cheaper stuff will deal with armour piercing rounds.

For the curious

Once upon a time there used to be a commercial product called 'siliclad' which had many uses. One side benefit was that glassware coated with this stuff suffered less breakage during routine washing.

I did not work on the project, but I understand a former employer of mine developed a polyurethane elastomer coating for chemical bottles. The system was fairly clear.

When we buy acids they come in glass bottles which have a clear plastic coating to make them shatterproof. Perhaps a little research will tell what this coating is.

Dear sir,

we are interested to have plastic coating on our lab glass wares. pl.send the details

where it can be done in India
