Applicant:

THE PATENT WELL LLC [US]

FR_3120809_A1

Absstract of: GB2608669A

Coated metal particles 10 comprise a coating 14 derived from a molybdate solution that is reactive to the uncoated metal. Typically, the metal is aluminium or aluminium alloy. Preferably, the coating comprises a molybdate oxide and is electrically conductive or semiconductive, with a thickness of 1 nm to 5 microns. The coating is normally free from chromium and/or lithium. The molybdate solution may comprise potassium molybdate with potassium permanganate and/or potassium hexafluorozirconate. The solution may be aqueous with a pH of 2-4 or 9-11. A corrosion-resistant composition comprising the coated metal particles and a binder is also disclosed, wherein the composition is suitable for application onto a metal substrate. The composition may comprise an ionic or organic corrosion inhibitor, which is lithium-free and may comprise synergistic combinations of metal oxalates, metal pirates, metal succinates, metal tartrates, and metal adipates. A method of manufacturing the coated particles is further claimed.

KR_20220020865_PA

Absstract of: CN112126372A

The invention provides an antistatic surface-protective film which has balanced adhesive force at a low peeling speed and a high peeling speed and can achieve both antistatic property and anti-foulingproperty. As a solution, a release film (5) on which a release agent layer (4) containing an antistatic agent is laminated is bonded to the surface of an adhesive layer (2) formed by crosslinking anadhesive composition via the release agent layer (4), and the antistatic agent of the release agent layer (4) is transferred to the surface of the adhesive layer (2). The adhesive composition comprises: (A) an acrylic polymer which is obtained by polymerizing an acrylic polymer and a (meth)acrylic acid ester having at least two or more alkyl groups having C1-C10 carbon atoms in a total of 100 parts by weight of the acrylic polymer; 2-Ethylhexyl acrylate is contained in an amount of 50 parts by weight or more, and one or more monofunctional methacrylate monomers having a homopolymer Tg of 0 DEGC or more are contained in an amount of 5-40 parts by weight in total; (C) an isocyanate compound having a trifunctionality or higher; (D) a crosslinking retarder; (E) a crosslinking accelerator other than a stannide.
