Not sure where I mentioned a 340F temp ?
Some of the info I related about his material in an earlier post is not completely accurate (Alzheimer's?) What follows is closer to the facts.
I am reading off a can of "Ceramit" as I write these notes. Here is my interpretation.
This material is an Acetate based resin, it contains Xylene, it is flammable. So it might attack some of the plastic based print media. Because of it's solvent base, proper ventilation and good housekeeping is a must for safe working conditions. As with any resin product it can be messy and a nightmare to clean up. Plan on this! Don't use this stuff in you kitchen!
It comes in many colors including a group of transparents. When cured it is quite hard and tough. No, it is NOT glass hard but it will not scratch off with you fingernail and it is much more durable than Pebeo and other heat cured acrylic paints. In many ways it is similar to working with epoxy or polyester resins. It is better to build up several thin layers rather than filling deep pockets all at one time. Applying too much at one time can cause bubbles to form and this is not pretty.
Ceramit cures
most effectively between 200F -300F (93C - 149C). But it will also cure at room temperature (above 70F) if left for 24 -48 hours. Once mixed, the working pot life is 14-16 hours. This can be extended by refrigeration. Personally, I only mix tiny amounts, use what I need then dispose of leftovers.
The working properties of Ceramit can be tailored to specific requirements of your project. Viscosity can be altered to optimize methods of application, such as: brush, spatula, spray, eye dropper, etc. Also, depending on mix ratios, you can adjust the final hardness of the coating. So if you apply this material to a springy plastic part you might want a more flexible coating. If it is applied to glass or metal you can adjust the ratio to get the hardest surface possible. Nice feature that!
It is an interesting product. It is modestly priced. Because it allows the user to alter it's working properties it encourages experimentation, and I am all for experimenting these days!
Now you know what I know, have at it.
