10-Methacryloyloxydecyl dihydrogen phosphate (10-MDP, MDP Monomer) is a chemical compound used in dental adhesive materials. This organophosphate monomer was developed in 1981 by the Japanese company Kuraray for the preparation of dental adhesion polymers [ 1 ]
A water-based primer, used primarily on wood. A primer (/ ˈ p r aɪ m ər /) or undercoat is a preparatory coating put on materials before painting.Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted.
The first use of compound adhesives was discovered in Sibudu, South Africa. Here, 70,000-year-old stone segments that were once inserted in axe hafts were discovered covered with an adhesive composed of plant gum and red ochre (natural iron oxide) as adding ochre to plant gum produces a stronger product and protects the gum from disintegrating ...
Thinset (also called thinset mortar, thinset cement, dryset mortar, or drybond mortar) is an adhesive mortar made of cement, fine sand and a water-retaining agent such as an alkyl derivative of cellulose. [1] It is usually used to attach tile or stone to surfaces such as cement or concrete. [2]
Methyl cyanoacrylate (MCA; also sometimes referred to as α-cyanoacrylate or alpha-cyanoacrylate) [3] is an organic compound that contains several functional groups: a methyl ester, a nitrile, and an alkene. It is a colorless liquid with low viscosity. Its chief use is as the main component of cyanoacrylate glues.
The wear of an adhesive tape as it slides across a substrate can be estimated using Archard's Law of Adhesive Wear, where and are the hardness and wear coefficients of the adhesive tape, is the distance the adhesive is dragged across the substrate surface, is the total normal load acting on the adhesive tape, and is the volume of the adhesive ...
As adhesives, epoxies bond in three ways: a) Mechanically, because the bonding surfaces are roughened; b) by proximity, because the cured resins are physically so close to the bonding surfaces that they are hard to separate; c) ionically, because the epoxy resins form ionic bonds at an atomic level with the bonding surfaces.
