摘要： A beard iron for straightening beard hairs includes a handle having a proximal end, a distal end, a dorsal side, and a ventral side. A hair iron is coupled to the distal end and comprises a heating plate and a heating element. The heating element warms a bottom side of the heating plate. A power source is coupled to the handle and is in operational communication with the heating element. A guide is coupled to the ventral side proximal the distal end and extends to rest adjacent the bottom side of the heating plate.

摘要： A method for converting spherical or amorphous metal particles into lamellar flakes that promote improved adhesive and cohesive characteristics when incorporated into coating compositions. The metal flakes produced exhibit properties compatible with binder chemistries such as isocyanates, titanates, titanate hybrids and are suitable for use in conjunction with advanced top coating techniques, such as electrodeposition. The particles produced by the method may be used in coatings and may exhibit improved substrate adhesion and improved cohesion characteristics when used in conjunction with an electrodeposition top coat.

摘要： The present development is a process for coating a substrate with a microlayered extrusion coating, or for producing a laminate from a first substrate, a microlayered extrudate and a second substrate. The present development also includes a microlayered extrusion coating used for laminating two or more plastic extrudates. The microlayered extrusion coating comprises a microlayer core comprising a plurality of layers of gas barrier material having a thickness of less than five microns per layer with alternating tie layers. The microlayer core is sandwiched between polymeric boundary layers which are further sandwiched between polymeric skin layers. The present microlayered extrudate surprisingly exhibits a gas barrier significantly better than conventional thicker single barrier layers and increased opacity in the extrudate using white pigmented LDPE enhances the printed graphics in a laminate structure using a printed substrate.
