Thread-locking fluid or threadlocker is a single-component adhesive, applied to the threads of fasteners such as screws and bolts to prevent loosening, leakage, and corrosion. Most thread-locking formulas are methacrylate -based and rely on the electrochemical activity of a metal substrate to cause polymerization of the fluid.
Loctite is an American [1] brand of adhesives, sealants, surface treatments, and other industrial chemicals that include acrylic, anaerobic, cyanoacrylate, epoxy, hot melt, silicone, urethane, and UV/light curing technologies. Loctite products are sold globally and are used in a variety of industrial and hobbyist applications.
Adhesive removers are intended to break down glue so that it can be removed from surfaces easily. [1] [2] [3] Formulations may be designed to remove a broad range of adhesives or to address a specific bond. [1] Many general purpose removers are intended to remove residue from adhesive tape.

Thermal paste consists of a polymerizable liquid matrix and large volume fractions of electrically insulating, but thermally conductive filler. Typical matrix materials are epoxies, silicones (silicone grease), urethanes, and acrylates; solvent-based systems, hot-melt adhesives, and pressure-sensitive adhesive tapes are also available.
A cooling bath or ice bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C. These low temperatures are used to collect liquids after distillation , to remove solvents using a rotary evaporator , or to perform a chemical reaction below room temperature ...
Limescale build-up inside a pipe reduces both liquid flow and thermal conduction from the pipe, so will reduce thermal efficiency when used as a heat exchanger.. A descaling agent or chemical descaler is a liquid chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, and kettles.
A standard flexible intermediate bulk container can hold 500 to 1,000 kg (1,100 to 2,200 lb) and manufacturers offer bags with a volume of 285–2,830 litres (10–100 cu ft). [2] Flexible intermediate bulk containers are made of woven polyethylene or polypropylene or other heavy polymers.
The bonding temperature is lower than with most other HMAs, only about 50 °C (122 °F) to 70 °C (158 °F), when the adhesive behaves as a soft rubber acting as a pressure-sensitive adhesive. The surface wetting in this amorphous state is good, and on cooling the polymer crystallizes, forming a strong flexible bond with high cohesion.
