The brand has established itself worldwide as a specialist in high-performance cleaning chemicals, precision tools, and consumables used in sensitive and demanding applications.
Whether it’s printed circuit boards, sensitive contacts, fiber-optic connections, or complex electronic assemblies—Chemtronics develops products that meet even the highest purity and performance requirements. The company combines decades of experience with continuous innovation to offer users safe, efficient, and sustainable solutions.
As part of Illinois Tool Works Inc., Chemtronics benefits from a strong global network and extensive technical expertise. The result is a broad portfolio—ranging from precision cleaners and desoldering braids to protective coatings and specialized fiber-optic cleaning systems.
In industries such as electronics manufacturing, telecommunications, aerospace, medical technology, and industrial maintenance, Chemtronics is regarded as a reliable partner when it comes to maximizing process reliability, product quality, and performance.

Cleaning swabs

Chemtronics cleaning swabs are suitable for precise cleaning tasks in electronics and sensitive technical environments. Depending on the model, they are available as standard cleaning swabs or for applications with ESD requirements, and they ensure reliable removal of particles, flux residues, and contaminants—even in hard-to-reach areas. High-quality foam or polyester tips enable effective cleaning with minimal lint and particle shedding. The various models are suitable for manufacturing, repair, maintenance, and other applications in the electronics industry.

Flux Pens

Chemtronics flux pens enable the precise application of flux directly to solder joints. The marker-like applicator allows for controlled dispensing of the required amount, preventing drips and waste. Special formulations promote optimal wetting of the solder surfaces, support even solder flow, and reliably remove oxide layers. Chemtronics also offers no-clean- and lead-free flux pens, which have been specifically developed for lead-free solders and low-maintenance applications. The pens are suitable for repairs, prototyping, or mass production and guarantee controlled processes and high-quality soldering results.

Flux remover

Chemtronics’ flux removers reliably dissolve rosin, no-clean, and lead-free flux residues and enhance the electrical reliability of assemblies. The Flux Remover Pens are ideal for precise cleaning, effectively removing residues from hard-to-reach areas. For large-area applications or mass production, the Flux-Off® Sprays are ideal: they coat circuit boards quickly and evenly, and some come with a brush attachment for stubborn residues. Both solutions ensure clean assemblies, reliable processes, and minimal rework.

Chemask®

Chemask ® from Chemtronics offers temporary protective masks for printed circuit boards and assemblies. The liquid masks are easy to apply and form a flexible, durable layer that protects sensitive areas during soldering, coating, or cleaning processes. Once the work is complete, the mask can be peeled off without leaving any residue or damaging circuit traces or components. Resistant to heat and chemicals, Chemask® is suitable for wave soldering, selective soldering, or conformal coating and guarantees clean delineation and process reliability.

Soder-Wick ® desoldering braids

Soder-Wick ® from Chemtronics enables the clean and controlled removal of solder. The finely woven copper mesh with integrated flux ensures efficient heat transfer and high capillary action, allowing molten solder to be absorbed quickly. Various strand widths adapt optimally to small SMD components or larger through-hole connections. Soder-Wick® reduces rework and ensures precise desoldering and reliable results.
