摘要:
A diffusively reflective paint composition is disclosed for use in reflectors in lighting fixtures. The paint is formed by blending macroporous polymeric particles with a paint carrier. The macroporous polymeric particles are formed by reducing a reflective macroporous sheet material. The paint can further comprise solid or hollow microspheres. The paint can be applied to a variety of substrates to form diffusely reflective articles.

Ophthalmic lenses, coatings for ophthalmic lenses, and methods for manufacturing ophthalmic lenses are provided herein. In one exemplary embodiment, an ophthalmic lens comprising a polymeric lens has a first surface and second surface. A coating overlies the first surface. The coating comprises a polysiloxane, a polyurethane, an oligomer derived from a polysiloxane or a polyurethane, a polymer derived from a polysiloxane or a polyurethane, or a combination thereof, and a fluorinated material. The coating exhibits a water contact angle of greater than 90° as measured by a goniometer.

An abrasive article includes a backing having first and second major surfaces, an abrasive layer overlying the first major surface, and a backsize layer overlying the second major surface. The backsize layer is formed from a formulation including a cationically polymerizable component, a radically polymerizable component, and at least 5% by weight of a nano-sized filler based on the weight of the formulation.

A radiation curable resin composition suitable for making three dimensional objects comprising at least one epoxy compound, a cationic photoinitiator, wherein the resin composition has a first color or no color before cure and wherein a three dimensional object made from the resin by subjecting the resin to radiation shows a second color which is different from the color of the resin composition before cure.
摘要:
A radiation curable composition comprising 10-90 wt % of a cationically polymerizable compound, 0.1-10 wt % of a cationic photoinitiator, 1-40 wt % of a radically polymerizable compound, 0.1-10 wt % of a radical photoinitiator and 5-70 wt % of a filler having a mean average particle size of between 3 and 500 nanometer.
摘要:
A method of forming a coated abrasive article includes providing a composite binder and abrasive grains on a backing. The composite binder includes at least 5 wt % of a particulate filler having an average particle size of less than 100 nm. The method also includes curing the composite binder.
摘要:
An optical filter composite is provided having effective filtering of infrared emissions, such as solar or laser emissions, while providing very high visible light transmission, preserving the ability to differentiate and recognize colors and providing a pleasing overall color as compared to the prior art. The present invention provides for filters that are formed by lamination, infusion and/or coating processes using filtering assemblies having a neutral color with high visible light transmission while also producing high levels of filtration in the infrared and near infrared range to provide effective protection against harmful emissions in these ranges while also producing a filter that has a color that is more pleasing and desirable to the wearer.
摘要:
The present invention relates to resin compositions suitable for making colored three dimensional objects and to methods for making colored three dimensional objects.

Optical filters, infrared (IR) blocking assemblies, and methods for fabricating optical filters are provided herein. In an embodiment, an optical filter includes a transparent base lens having a first surface and a second surface. The optical filter includes an anti-fogging layer as an outermost layer connected to the first surface of the base lens. Further, an infrared (IR) blocking film is bonded to the second surface of the base lens. The IR blocking film includes reflective layers configured to transmit no more than about 40% of IR light.
