Polyurethane can be recycled.
Crystal glass contain lead.
Newsprint does not contain lead. It is typically made from wood pulp and does not require the use of lead in its production process.
yes they do
No, Armetale is a type of aluminum-based alloy that does not contain lead. It is safe for use with food and does not leach harmful chemicals.
If a polyurethane varnish (not lacquer) contained linseed oil, it COULD have lead in it - lead is a drying agent for that oil. It was mostly used in paints as a pigment. Varnish has no pigment and it dries by chemical reaction, so most polyurethane varnishes don't need lead.
Urethanes react with water and alcohols. To use lacquer thinner you need to be sure that it contains no IPO or IPA. Cheap lacquer thinners probably contain mainly toluol xylol and ketones; these should be OK. Just thin a little urethane lacquer and its hardener with the lacqer thinner and let it stand or apply to a small test patch. If it froths or goes funny in any way; forget it
spray polyurethane is best, but lacquer will work as well, it is cheaper and dries in an hour versus 24-48, but you should apply multiple layers. 3 layers with poly, 6-10 with lacquer
No. You can use lacquer on oil too. Varnish will work well with oil stain as do any of the wax finishes
If you are using polyurathane paint, using a general purpose lacquer thinner is not recommended, other than for cleaning equipment afterwards. For application, use only the correct thinners, of the same brand as the paint.
Lacquer thinner evaporates quicker. It is cleaner or leaves less of a film than paint thinner. Lacquer thinner will thin most solvent based paint but paint thinner shouldn't be used to thin Lacquer. Lacquer dries from the surface painted out and enammal dries from the surface of the paint down to the surface painted. Using the wrong thinner affects how the paint dries and may affect the final finish.
Generally speaking, you don't brush lacquer....it has to be sprayed. With that being said there are probably some products that you can brush on if you feel that you must. You would want to use either a china bristle brush, or a "natural" brush. Please know that when you use lacquer thinner to clean your brushes, it may soften the glue that bonds the bristles to the handle. I would use a polyurethane or urethane if you need to apply it by brush. You can put either on top of lacquer if you want to (but you cannot put a lacquer on top of the poly).
Lacquers contain many volatile organic componds undesirable by inhalation.
If you don't want to alter the wings structurally or add too much weight, I would say spray the outer surface with a polyurethane lacquer.
When polyurethane is exposed to chlorine, it can undergo a chemical reaction that can result in degradation of the material. This reaction can lead to discoloration, embrittlement, and reduced mechanical properties of the polyurethane. It is important to avoid exposing polyurethane to chlorine-containing substances to maintain its integrity and performance.
Yes, that was the original intention of urethane.
No. It doesn't contain lead.
