A hardenable (e.g. dental) compositions is described comprising an encapsulated material. The encapsulated material comprises a basic core material and an inorganic shell material having certain viscosity criteria. Also described are dispensing devices and kits are described comprising a hardenable (e.g. dental) composition comprising a liquid material and an encapsulated material wherein the encapsulated material comprises a basic core material and an inorganic shell material comprising a metal oxide surrounding the core. The dispensing devices and kits can facilitate the methods of applying the hardenable composition. The hardenable or hardened (e.g. cured) composition can provide various technical effects such as a delayed release of a basic core material, a delayed increase in basicity, promoting remineralization of a tooth or bone structure, and increasing the average alkaline phosphatase (ALP) activity of pulp cells. In some embodiments, the composition is a dental (e.g. sealant) composition for application to a tooth structure.

A method of applying a two-part dental sealant is described comprising providing a syringe device () comprising a cartridge () including first and second chamber. The first chamber contains a first part of a dental sealant comprising a (meth)acrylate resin and an oxidizing curing agent. The second chamber contains a second part of a dental sealant comprising a (meth)acrylate resin and a reducing curing agent that reacts with the oxidizing curing agent of the first chamber. The first and/or second part of the dental sealant further comprise a single component or multiple components that neutralize acid and promote remineralization. The syringe device comprises a dispensing nozzle () comprising a static mixer and an outlet at one end of the cartridge and a plunger () at the opposing end of the cartridge. Also described is a kit for storing and applying the dental sealant is described.

A plurality of non-white roofing granules is provided. The roofing granules include a plurality of particles including mineral fines and a calcia-based cement binder; and a non-white pigment-containing coating disposed on at least a portion of exterior surfaces of the particles. Methods of making the roofing granules are also provided. One method includes: mixing material including mineral fines and a calcia-based cement binder to provide agglomerates; curing the agglomerates to provide particles; and coating at least a portion of exterior surfaces of the particles with a non-white pigment-containing coating. Another method of making the roofing granules includes: providing an aqueous dispersion in a tool having cavities, the aqueous dispersion including mineral fines and a calcia-based cement binder; curing the aqueous dispersion in the tool to provide particles; and coating at least a portion of exterior surfaces of the particles with a non-white pigment-containing coating. The roofing granules exhibit an intrinsic total solar reflectance greater than 0.3. Often, the roofing granules contain by-product mineral fines.

The disclosed retroreflective element includes a polymeric core that is loaded with a plurality of first beads and second beads distributed at the perimeter of the core. The first beads are different than the second beads. Because of the beads in the core, the retroreflective element remains useful for returning light even after portions of the core begins to wear away. Further, when the retroreflective elements get wet, water will settle to the bottom of the perimeter of the core. Therefore, using the second beads with a refractive index suited for wet conditions, while the first beads have a refractive index suited for dry conditions allows the retroreflective element to be useful in both wet and dry conditions even while the retroreflective element wears during use.
