A thermoset is a material that cures or sets into a given shape, generally through the application of heat. A cured, thermoset material will not remelt or otherwise regain the processibility it had before being cured. Curing changes the material forever.
A thermoplastic material softens (becomes pliable and plastic) when heated, but it does not cure or set. It can be reheated to be reformed.
The main difference between polyurethane and thermoplastic polyurethane is that PU is chemical bonded while TPU is heat bonded. TPU tends to feel softer and more like fabric than PU which has a more plastic feel.
In thermoplastic polyurethanes , phase separation dose not exist but in thermoplastic elastomer polyurethanes phase separation has occured .
Doas anybody knows?
Yes. Because a chemical bond is no longer possible because the epoxy coating has dried, a mechanical bond is required. This merely means that the cured epoxy must be lightly sanded before applying the next layer: the first coat should have a matt, nearly white finish.
A woody stem is usually much bigger and has a woody coating, like a tree. A herbaceous stem is softer and more flexible, like a flower stem.
Non metallic coating is not very stable except Graphite coating other coating includes Sulphur coating and organic coating of polymers the temporary coating of wax ,grease and oils also may be used.

Epoxy and polyurethane can be mixed. An epoxy and polyurethane coating system is often used in the marine industry to protect against the weather.

Powder coating is commonly used on metals to give a smooth finish. The materials used in it include thermoplastic or thermoset polymers.
Pipe Lining refers to the internal diameter, pipe coating is external.
It is a waterproofing seal but heat readily passes through it.

The difference between the conventional coating and film coating depends with the material used. The film coating uses a film to coat while the conventional coating does not use any type of material to coat.
Epoxy-polyester powder coating is a hybrid of epoxy and polyester powder coating, and galvanised is coating thickness for steel bars and components is between 3 and 4 mils.
Yes. There is a product called Bar Top that dries as a clear, thick coating on wood.
Doas anybody knows?
EC has a time release coating on it. Sh
Powder coating is free-flowing, dry powder. It differs from regular paint in that paint requires a solvent while powder coating does not. The coating is usually applied electrostatically.
