Abstract: A paint bell cup for directing a spray of paint onto a surface includes a cup body having an outer surface, an inner conical surface having a circumferential edge, and a stem extending from the outer surface. The stem includes a passage that delivers paint toward the inner conical surface. The cup body includes one or more spray control features that extend along the inner conical surface toward the circumferential edge. The one or more spray control features promote a selected uniform droplet size of the paint traveling from the stem toward the circumferential edge.

Abstract: A heating system includes a conveying system configured to transport a plurality of vehicle body-in-whites (BIWs) sequentially through an oven room to cure paint applied in a paint room. A preheating system includes one or more robot arms. A heat source is connected to the one or more robot arms. A controller is configured to control the one or more robot arms based on a position of one of the vehicle BIWs on the conveying system and to position the heat source near or in direct contact with one or more inner components of the one of the vehicle BIWs to heat the one or more inner components prior to the one of the vehicle BIWs entering the oven room.

Abstract: An adhesive composition includes an epoxy component and an additive component reactive with the epoxy component. The additive component includes an imidazole present in an amount of less than or equal to 10 parts by weight based on 100 parts by weight of the adhesive composition, and an amine present in an amount of less than or equal to 5 parts by weight based on 100 parts by weight of the adhesive composition. The epoxy component and the additive component are present in the adhesive composition in a ratio of from 1:1 to 15:1. A method of forming a component includes curing the adhesive composition at a temperature of less than or equal to 150° C. for less than or equal to 30 minutes to thereby join the first substrate and the second substrate.

Abstract: During an example coating method, a metallic substrate is provided. A foundation coat precursor is applied on the metallic substrate. The foundation coat precursor includes a matrix and a plurality of capsules present in the matrix. Each capsule includes a shell and a healing agent surrounded by the shell. A basecoat precursor is applied, and a clearcoat precursor is applied. The metallic substrate, the foundation coat precursor, the basecoat precursor, and the clearcoat precursor are heated i) after each respective application or ii) simultaneously, in order to cure the foundation coat, basecoat, and clearcoat precursors and respectively form a foundation coat, a basecoat, and a clearcoat. The foundation coat is ultraviolet (UV) stable and bonds the metallic substrate to the basecoat and the clearcoat.

Abstract: A method of forming a cured film on an aluminum substrate includes depositing a film formed from a sol-gel coating composition onto the aluminum substrate without disposing a conversion coating composition onto the aluminum substrate. The method also includes, after depositing, curing the film. A coating system includes an aluminum substrate having a surface and a cured film disposed on and in contact with the surface. The cured film is formed from a sol-gel coating composition. The coating system is free from a layer formed from a conversion coating composition.
