Weicon Surface Cleaner 400 ml is a solvent-based technical spray developed to degrease surfaces during assembly and maintenance operations. In preparation before bonding or sealing, it helps reduce oil, dirt, and film layers on the surface, supporting more stable downstream processes. Thanks to its fast-evaporating formula, it creates a working-ready surface without leaving residue after application. The manufacturer is WEICON GmbH & Co. KG, headquartered in Germany.

Surface pretreatment with Weicon Surface Cleaner
This technical spray is positioned for cleaning and degreasing surfaces that will be joined or sealed. Its transparent (colorless) nature and residue-free evaporation help maintain a “clean surface” standard, especially on parts with tight tolerances. Being silicone-free is a design choice that can help reduce the risk of unwanted slippery films in certain processes. Its AOX-free composition can be considered a practical advantage for operations seeking compatibility with specific industrial cleaning approaches and specifications. The minimum shelf life at room temperature is stated as 24 months; since the container is pressurized, storage conditions should be observed carefully.

Chemical composition and performance characteristics
The product has a blend that mainly contains aliphatic hydrocarbons (C6–C7 range) and alcohol-based solvents, focusing on dissolving oils and similar contaminants. Rapid volatility can shorten waiting time after cleaning and positively support cycle times on production lines. However, because the aerosol format is classified as “extremely flammable,” it must be used away from open flames, sparks, and hot surfaces. Good ventilation at the application area is important to reduce exposure to solvent vapors. The product is also listed in the cleaning/degreasing category with marine and industrial supply codes (IMPA/ISSA).

Application method and process integration
Before use, shake the can thoroughly to stabilize the spray pattern and ensure even distribution on the surface. A typical approach is to spray in short bursts, allow a brief contact time, then wipe off the loosened contamination with a clean cloth; the procedure can be repeated for heavy soiling. This technical spray can be integrated as the first step in processes that require an “oil-free surface,” such as before bonding, sealing, labeling, or painting. Since solvent sensitivity can vary across plastics and painted surfaces, it is good practice to check compatibility on a small, inconspicuous area first. Due to the pressurized packaging, the product should not be exposed to direct sunlight and must be protected from temperatures above 50°C.

Sector-specific applications and compatible substrates
In metalworking and machine manufacturing, it can be widely used for degreasing prior to part assembly and for cleaning mechanical equipment components during maintenance. In automotive and supply industries, it supports surface preparation before sealing applications or taping/labeling; in maintenance workshops, it offers a practical technical spray option for quick cleaning needs. In electrical/electronics assembly, reducing oily films on surfaces can support reliability; in HVAC and general facility maintenance, it can help with cleaning connection areas and similar steps. Compatible substrates include metal, glass, ceramic, and most plastics; however, controlled testing is recommended on sensitive plastics, varnished/coated surfaces, and freshly painted areas. WEICON Surface Cleaner is a functional pretreatment product focused on meeting the “clean and dry surface” requirement before applying adhesives and sealing materials.
