Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
A powder product containing plastic particles and metal flake particles yielding in a continuous film an 85° gloss of at least 80%, a total reflectance of at least 50%, and a 45° gloss of at least 55% (half-scale reading), wherein the metal flake particles are aluminum and the plastic particles are based on thermosetting epoxy resin, have a specific gravity of 1.15 to 1.98, a melting point of 185° to 205° F., a time to gel of approximately 100 to 120 seconds at 360° F. and volatiles of less than one weight-%.
Claim 2
Dependent Claim
92 words
A powder product containing plastic particles and metal flake particles yielding in a continuous film an 85° gloss of at least 80%, a total reflectance of at least 50%, and a 45° gloss of at least 55% (half-scale reading), wherein the metal flake particles are aluminum and the plastic particles are based on thermosetting epoxy resin, have a specific gravity of 1.15 to 1.98, a melting point of 185° to 205° F., a time to gel of approximately 100 to 120 seconds at 360° F. and volatiles of less than one weight-%.
Claim 3
Dependent Claim
33 words
A powder product as claimed in claim 1, wherein the metal flake particles are present at less than 30 weight-% as based on the total weight of metal flake particles and plastic particles.
Claim 4
Dependent Claim
95 words
A powder product consisting essentially of plastic particles and metal flake particles and capable of being melted to yield in a continuous film 20°, 60°, and 45° (half-scale reading) glosses of at least 100% and a total reflectance of at least 50%, wherein the metal flake particles are aluminum and the plastic particles are based on thermosetting epoxy resin, have a specific gravity of 1.15 to 1.98, a melting point of 185° to 201° F., a time to gel of approximately 100 to 120 seconds at 360° F. and volatiles of less than one weight-%.
Claim 5
Dependent Claim
95 words
A powder product consisting essentially of plastic particles and metal flake particles and capable of being melted to yield in a continuous film 20°, 60°, and 45° (half-scale reading) glosses of at least 100% and a total reflectance of at least 50%, wherein the metal flake particles are aluminum and the plastic particles are based on thermosetting epoxy resin, have a specific gravity of 1.15 to 1.98, a melting point of 185° to 201° F., a time to gel of approximately 100 to 120 seconds at 360° F. and volatiles of less than one weight-%.
Claim 6
Dependent Claim
33 words
A powder product as claimed in claim 3, wherein the metal flake particles are present at less than 30 weight-% as based on the total weight of metal flake particles and plastic particles.
