WEICON AT-44 Allround-Spray is a multi-purpose technical spray with PTFE and no silicone, designed to combine lubrication, water displacement, cleaning, corrosion protection, and surface protection in a single product. With a formula aimed at a low coefficient of friction, it offers a practical solution for maintenance needs such as loosening seized fasteners, reducing squeaks, and leaving a thin protective film. After application, it forms a \u201crazor-thin\u201d layer on the surface, helping reduce run-off and stickiness while providing an advantage in general maintenance thanks to its non-dust-attracting character. The product is developed by WEICON GmbH & Co. KG (Germany) and is supplied in aerosol form for industrial maintenance use.<\/p>\n
AT-44 Allround technical spray: product description and intended use
\nThis technical spray penetrates moving mechanical components quickly, helping address issues caused by rust and seizure, and is positioned as an all-purpose maintenance oil solution. It targets a loosening effect on \u201cstuck\u201d parts such as threaded connections, bolts, fittings, and valves, while also covering use cases aimed at displacing moisture on electrical cables and reducing the risk of leakage currents. It is preferred in maintenance applications to reduce squeaking and friction noises in door hinges, guide rails, bearing seats, and various joint\/coupling types. It also cleans dirty surfaces and leaves a protective film that helps safeguard tools, machines, and sensitive electrical and mechanical devices.<\/p>\n
Technical features and performance parameters
\nThe product is described as pale yellow and transparent with a vanilla-like odor profile, and it is specified to have a minimum shelf life of 24 months at room temperature. Its kinematic viscosity values are given as 21 mm\u00b2\/s at 40\u00b0C and 4 mm\u00b2\/s at 100\u00b0C, which technically describes how its lubrication behavior changes with temperature. With a temperature resistance range of -50\u00b0C to +210\u00b0C, it offers practical applicability in technical spray form for maintenance points requiring a wide operating range. On the approvals\/codes side, ISSA Code 53.402.24 and IMPA Code 450830 are provided, which are useful for matching in industrial procurement and marine purchasing processes.<\/p>\n
Chemical composition and working principle
\nThe nature of the formulation is described through its PTFE content and silicone-free approach, aiming to support smooth operation in moving surfaces by creating a lubricating film with low friction. Safety documentation lists propane and butane as aerosol propellants, while the carrier\/solvent phase includes component classes such as hydrotreated petroleum distillates and hydrotreated naphtha, providing a framework that explains the product\u2019s \u201cpenetration + film-forming\u201d behavior. This structure enables multiple functions\u2014forming a thin layer on the surface while displacing moisture and providing corrosion protection\u2014in a single application. The role of PTFE is associated with a surface film approach that reduces friction and increases lubricity.<\/p>\n
Application method, compatible surfaces, and practical usage tips
\nIt is recommended to shake the can well, apply from approximately 5 cm, and allow about 30 seconds of dwell time; this duration serves as a practical reference for penetration and spread on the surface. It is compatible with maintenance\/lubrication applications on moving metal parts, fasteners, hinge-guide systems, and various machine components, and it also includes moisture-displacement use cases on electrical cables. Since the thin film it leaves is described as \u201cnon-smearing\/non-sticky,\u201d it can offer an advantage where a clean finish and low dust pick-up are desired after maintenance. As it is a pressurized aerosol, it is critical for storage to protect it from direct sunlight and avoid exposure to temperatures above +50\u00b0C.<\/p>\n
Sector-based applications and key advantages
\nIn maintenance and repair (MRO) operations, it is a widely used auxiliary product for quick interventions aimed at periodic protection of equipment on production lines and reducing downtime due to \u201csudden failures.\u201d In automotive and the supply industry, it can be used on door lock\/hinge mechanisms, fasteners, and moving joint areas; in machinery manufacturing and maintenance services, it is suitable for general multi-purpose use around bearings, slide\/guide assemblies, and overall assembly parts. In electrical and electronics maintenance, applications around cables\/connectors stand out with the aim of displacing moisture and protecting surfaces; in marine and industrial procurement, the ability to identify it via ISSA\/IMPA codes provides operational convenience. Being silicone-free can be a selection criterion in maintenance areas where silicone contamination is undesirable, while the PTFE content supports a low-friction, lubricating film approach.<\/p>\n","protected":false},"excerpt":{"rendered":"
