The present invention is a thermal inkjet ink that provides good reliability at a wide range of industrial print conditions from both low temperature to high temperature environments across a broad range of humidities. It is particularly advantageous in low-temperature applications, for example, printing at temperatures down to 5° C. or lower continuously for 8 hours without developing print defects which can lead to unreadable codes; and, in the meantime also maintains other critical functional aspects including contrast, wetting, decap time, dry time, adhesion, ink cartridge stability, etc. The inks contain one or more binder resins that exhibit a hydroxyl number or acid number of at least 100 mg KOH/g; one or more terpene phenolic resins; one or more volatile organic solvents; and one or more dyes, and optionally further components.

The present application discloses an insulated wire and a preparation method thereof, a coil and an electronic/electrical device. According to the insulated wire, a bonding layer containing PEEK nano-powder is arranged between a conductor and a PEEK resin insulating layer, and a bonding agent for forming the bonding layer contains organic solvent, polyamide-imide resin and PEEK nano-powder material which are mixed. The bonding layer can be well bonded with both the conductor material and the PEEK resin insulating layer, so that the produced insulated wire rod has good adhesion, and cracking and detachment will not appear during application.

The present invention relates to a fire protection composition comprising a component A and a component B. Component A comprises an epoxy liquid resin and ammonium polyphosphate. Component B comprises an adduct B1 of (i) at least one polyamine having at least three amine hydrogens reactive toward epoxide groups with (ii) at least one epoxide, an ether group-containing aliphatic primary diamine B2, and an aliphatic or cycloaliphatic primary diamine B3. The fire protection composition has good adhesion to metal, and after passing through burning-in ovens in the automotive industry still shows good fire protection values with a low mass loss and is suitable for spray application.
