Disclosed are methods of protecting porous substrates and/or increasing the peel-resistance of coatings and stains for porous substrates. The methods may include providing a stain or coating comprising a microencapsulated self-healing material; and applying the stain or coating to a porous substrate. Damage to the stain or coating may release the self-healing material at a site of damage, such as a crack or scratch in the stain or coating. The self-healing material may be a polymeric precursor, an unsaturated polyester resin or alkyd, a fatty acid-based natural oil or derivative thereof, or a cross-linkable silane or siloxane monomer or resin. The microencapsulated self-healing material may include a microcapsule having a shell wall that includes a thermosetting polymer or a thermoplastic polymer; the thermosetting polymer may include urea-formaldehyde, melamine formaldehyde, polyurethane, polyurea, or polyacrylate; and the thermoplastic polymer comprises poly(methyl methacrylate), poly(lactic acid), or poly(glycolic acid).

Compositions, methods, and products that improve the adhesion of markings, for example, thermoplastic road markings, to substrates are disclosed. In some embodiments, such thermoplastic road markings include, but are not limited to, striping, solid lines, broken lines, and other traffic safety or informative markings placed on a substrate.

A porous material having a hierarchical pore structure, wherein a size and shape of interconnection parts of at least one level pore cavities is consistent with a size and shape of interconnection parts between the level pore cavities and the previous level pore cavities thereof, and an average value of equivalent diameters of the interconnection parts is larger than 45% of that of a diameter of small pore cavities of two adjacent pore cavities of the interconnection parts. The method for preparing the porous material includes: mixing a raw material powder with a pore-forming agent used for preparing the smallest level pores to formulate a slurry; uniformly filling the slurry into a polymeric material frame, and drying and crushing to form mixed grains; then uniformly mixing the mixed grains with the pore-forming agent used for preparing the upper-level pore cavities, forming a compact green body and sintering.

A preform intended for the production of a dental prosthesis. The preform includes a group of agglomerated ceramic, glass-ceramic or glass particles, such that, as volume percents: more than 40% and less than 90% of the particles of said group have a size greater than 0.5 ?m and less than 3,5 ?m, said particles hereinafter being denoted enamel particles, and more than 10% and less than 60% of the particles of said group have a size greater than 3.5 ?m and less than 5.5 ?m, said particles hereinafter being denoted dentine particles. The microstructure of the preform is such that there is an axis X, termed axis of variation, along which the Ve/(Ve+Vd) ratio changes continuously, Ve and Vd denoting the volume percents of enamel particles and of dentine particles, respectively. The enamel and dentine particles representing, together, more than 90% of the volume of the agglomerated particles.

The invention relates to a device for guiding liquid, in particular a drainage channel, comprising a guiding section (10) and at least one functional region (11), wherein the guiding section (10) is formed of concrete, which has a binder and a filler having a first grain size K.sub.1, wherein the functional region (10) is formed at least partially of a filled reaction resin, which has a filler having a second grain size K.sub.2, wherein K.sub.2<K.sub.1.

A ceramic and plastic composite and a method for fabricating the same are disclosed. A chemical cleaning treatment, a microetching treatment, a hole reaming treatment, and a surface activating treatment are performed on the surface of a ceramic matrix to form nanoholes with an average diameter ranging between 150 nm and 450 nm. Plastics are injected onto the surface of the baked ceramic matrix to form a plastic layer. The plastic layer more deeply fills the nanoholes to have higher adhesion. Thus, the higher combined strength and air tightness exist between the ceramic matrix and the plastic layer to improve the reliability and the using performance of the ceramic and plastic composite.
