The present invention relates to a substrate having (a) a first material applied to at least a portion of the substrate, and (b) a coating layer deposited from a powder coating composition including a film-forming resin, and optionally a crosslinker that is reactive with the film-forming resin, in direct contact with at least a portion of the substrate to which the first material has been applied. The first material is (i) a catalyst that catalyzes cure of the powder coating composition, (ii) a component reactive with the film-forming resin and/or the crosslinker of the powder coating composition, and/or (iii) a rheology modifier.

Coated substrates and methods of preparing the same

Disclosed is a system for treating a surface of a multi-metal article. The system includes first and second and/or third conversion compositions for contacting at least a portion of the surface. The first conversion composition includes phosphate ions and zinc ions and is substantially free of fluoride. The second conversion composition includes a lanthanide series metal cation and an oxidizing agent. The third conversion composition includes an organophosphate compound, an organophosphonate compound, or combinations thereof that optionally may include at least one transition metal. Methods of treating a multi-metal article using the system also are disclosed. Also disclosed are substrates treated with the system and method.

Two-step pretreatment system and method

The present invention is directed towards an aqueous alkaline cleaner composition comprising: an iron cation, a molybdenum cation, a cobalt cation, or combinations thereof; and an alkaline component; wherein the pH of the aqueous alkaline composition is at least 10, and the aqueous alkaline composition includes no more than 50 ppm of phosphate. Also disclosed are treatment systems comprising an aqueous alkaline composition for treating at least a portion of a substrate, and a pretreatment composition for treating at least a portion of a substrate. Also disclosed are substrates treated according to the disclosed treatment systems.

Alkaline molybdenum cation and phosphonate-containing cleaning composition

Polysulfide compositions having a polyether synergist are disclosed. Polysulfide compositions that contain polyether synergists exhibit a rapid onset of cure and have acceptable final properties. The polysulfide compositions can be used as sealants.

Controlled cure rate using polyether-coated synergists

Compositions include a polythiol and a wetted filler. The composition comprises from 0.1 wt % to 10 wt % water based on the total weight of the composition. The compositions exhibit an extended working time and a rapid onset of cure. The compositions can be used as sealants.

Controlling cure rate with wetted filler

The present invention includes a process for producing treated filler that includes (a) treating a slurry that includes untreated filler, where the untreated filler has not been previously dried, with a treating composition that includes a treating agent, thereby forming a treated filler slurry, and (b) drying the treated filler slurry to produce treated filler. The treating agent can include a polymer having (i) at least one first group that interacts with the untreated filler and (ii) at least one second group that interacts with a rubber matrix into which the treated filler is incorporated. The present invention also is directed to treated filler prepared by the process, as well as rubber compounding compositions and tires including the treated filler.

Treated fillers, compositions containing same, and articles prepared therefrom

An optical system for the detection of skin disease, such as melanoma, acquires images of a lesion on a subject's skin at different wavelengths and utilizes a sweeping arm rotating about the lesion in a clock-like sweep to produce diagnostically relevant metrics and classifiers from the image data so as to enhance detection of the skin disease.

System and method for optical detection of skin disease

The present invention includes a process for producing treated filler that includes (a) treating a slurry that includes untreated filler where the untreated filler has not been previously dried, with a treating composition that includes a treating agent, thereby forming a treated filler slurry, and (b) drying the treated filler slurry to produce treated filler. The treating agent can include an unsaturated fatty acid, derivative of an unsaturated fatty acid, or salt thereof. The present invention also is directed to treated filler prepared by the process, as well as rubber compounding compositions and tires including the treated filler.

The present invention is directed to a separation medium comprising rotary dried or spray dried precipitated silica. The silica has a pore surface area P wherein logP&#x3e;2.2, and the ratio of BET to CTAB is at least 1.0 measured prior to any surface modification of the silica. The present invention is further directed to a method of separating suspended or dissolved materials from a fluid stream, comprising contacting the stream with the separation medium described above.

Precipitated silica sorbents and method of separating materials from a fluid stream

The present invention is directed to a process for producing treated filler including (a) treating a slurry of untreated filler which has not been previously dried, with a treating composition including an organosilane material of specified structure (I); and (b) drying the treated filler slurry. The present invention also is directed to treated filler prepared by the process, as well as rubber compounding compositions and tires including the treated filler.
