The present invention discloses a hybrid (mixed) formulation composition for 3D additive manufacturing and a manufacturing process. The hybrid formulation composition possesses capability of UV radiation curing and thermal curing. The hybrid formulation composition is designed to be cured by UV radiation in the 3D printing/additive manufacturing process and then post cure by heat to get its final properties. The hybrid formulation composition consists of acrylates (oligomer, monomer, and diluent), photoinitiators, and isocyanate-containing prepolymers which comprises polyols (di-ol, tri-ol) and isocyanates. The hybrid formulation composition may also include reaction accelerator, dye, pigment, and fillers. The finished products of the hybrid formulation composition possess rubber-like properties and can be used in the applications such as shoe sole, toys, medical, and wearables goods . . . etc.

Coating compositions are disclosed that include corrosion resisting particles such that the coating composition can exhibit corrosion resistance properties. Also disclosed are substrates at least partially coated with a coating deposited from such a composition and multi-component composite coatings, wherein at least one coating later is deposited from such a coating composition. Methods and apparatus for making ultrafine solid particles are also disclosed.

This invention relates to urethane acrylic hybrid polymer dispersion with robust dry/wet adhesion and the basecoats prepared therefrom for automotive applications. In this system, the polyurethane dispersion (PUD) prepolymer is based on a combination of polyols and aliphatic diisocyanates. The acrylic portion is based on (meth)acrylated monomers. A combination of this hybrid polymer dispersion and other resins having defined glass transition temperature (T.sub.g) values, organic and/or inorganic rheology modifiers, and different additives including pigment, dispersant, and defoamer are used to prepare waterborne basecoats having modified appearance and performance. The final coatings show excellent dry/wet adhesion to the primer for automotive applications.

A composition and a method for manufacturing the composition are provided that includes a thermoplastic polyurethane (TPU) and a second component in an amount in the range of about 3% to about 60% by weight of the composition. The second component includes at least one reactive diluent, monomer, or oligomer (RDMO). The RDMO and/or the TPU may be cross-linked to form a semi-interpenetrating polymer network or an interpenetrating polymer network. The RDMO provides improved physical properties, such as rigidity, durability and strength, to the TPU. The polymer network may be bonded to other layers for certain applications, such as windows and flooring, to improve flexibility and strength, inhibit shattering and/or resist scratching and staining.
