An adhesive composition of general use is described, and particularly suitable for welding plastic parts, in the form of a two-component composition. The first of the two components being a cyanoacrylate based glue, and the second of the two components includes a blend, in powder form, of a polymeric origin component and an organic origin component.

A loupe is bonded to a glasses-type holder to be worn around a head of a user. The loupe includes: a tube framework inserted into a hole or a cutout formed in the glasses-type holder and bonded with a UV adhesive; and a lens held in the tube framework. At least a portion at which the UV adhesive is applied in the tube framework is made of a resin not resistant to acetone and is covered with a paint resistant to acetone.

The invention relates to a method comprising the following steps: first, mixing ground ABS and acetone, the latter varying according to the desired viscosity; second, beating the mixture; third, leaving the mixture to rest in a sealed environment; and fourth, beating the mixture again until same is homogeneous, and leaving to rest for 24 hours.

An antistatic composition contains an ambient-temperature molten lithium salt dihydrate, and one of a polymerizable compound, a plastic resin, an elastomer and an adhesive resin in which the lithium salt dihydrate is dispersed. The lithium salt dihydrate contains two types of lithium salts with different molecular weights from each other. The two types of the lithium salts are selected from a group of lithium salts each containing an anion having a fluoro group and a sulfonyl group.

Process for producing a pressure-sensitive adhesive comprising expanded microballoons, wherein the constituents for forming the adhesive are mixed in a first mixing assembly, the mixed adhesive is transferred into a second mixing assembly into which, at the same time, unexpanded microballoons are fed, the microballoons are expanded in the second mixing assembly or on exit from the second mixing assembly, the adhesive mixture with the expanded microballoons is shaped to a layer in a shaping assembly in which expanded microballoons which have broken through the surface are pressed into the layer surface and the layer of adhesive mixture together with the expanded microballoons are optionally applied to a weblike backing material.
