Orapi 507 NDI is a solvent-based technical spray developed for the rapid removal of oil, grease, and contaminant residues from industrial surfaces. It is especially suitable for pre-assembly cleaning and surface preparation before painting, helping to achieve a dry and residue-free surface. Official technical information highlights its fast evaporation, chlorine-free solvent formulation, and its ability to prepare surfaces for subsequent bonding or painting processes. Manufactured by ORAPI in France, this technical spray is supplied in a 650 ml aerosol can.

Product Description and Technical Structure of Orapi 507 NDI
507 NDI is defined as a cleaner and degreaser classified for professional use. The official safety documentation indicates that the product consists of a mixture containing hydrocarbons, ethyl acetate, methylal, isopropanol, and acetone; this composition supports its fast-cleaning and quick-drying performance. Its technical spray form allows controlled application on parts, pipes, and hard-to-reach industrial areas. In this respect, the product is positioned as a functional technical spray solution used for surface preparation in maintenance and production environments.

Performance Features and Surface Preparation Capability
Official product pages state that the product evaporates very quickly and completely, providing residue-free cleaning. In addition to removing oils, greasy deposits, and harmful contaminants, it is also reported to dissolve certain acrylic-type varnishes. For this reason, it stands out in pre-assembly cleaning, pre-paint preparation, and applications requiring a completely dry surface. Since official sources also clearly state that it can be used before bonding and painting, this technical spray is particularly suitable for process-oriented surface conditioning.

Application Method and Compatible Surfaces
The product can be used on metal surfaces, locks, chains, cables, various parts, and pipe systems requiring a completely dry surface. Official sources also emphasize its suitability for applications where dry surfaces are required in lines that come into contact with certain gases or oxygen. For plastics or different materials, a compatibility test is recommended in advance; therefore, it should not be generalized for all surfaces without verification. It should not be sprayed onto hot surfaces, and application must be carried out in well-ventilated areas.

Areas of Use, Advantages, and Safety Framework of 507 NDI
This technical spray can be used in metalworking, maintenance workshops, assembly lines, pre-paint preparation processes, mechanical part cleaning, and the cleaning of industrial pipe equipment. Its main advantages include rapid evaporation, residue-free cleaning, a chlorine-free solvent formula, and the ability to prepare surfaces for subsequent processes. Official safety classifications indicate that the product is highly flammable, may cause skin and eye irritation, and its vapors may cause dizziness; therefore, it should be handled in accordance with professional-use practices. The same documentation also includes a warning regarding long-term toxicity to aquatic life, making controlled use and proper waste management important.
