Koube Química consolidates expansion with "workshop tests" and launches financial challenge to prove the effectiveness of its products
In a scenario of strong competitiveness in the auto parts industry, Koube Química do Brasil, headquartered in Araucária (PR), recorded an expansion of 40% in 2025. The result made the brand one of the most advanced in the automotive chemical solutions segment in the country, paving the way for the 2026 strategy, which includes entering the electrified vehicle niche.
The company, founded 23 years ago, uses a validation methodology that is uncommon in the industry: the “workshop proof”. Before reaching the shelves, the products developed in the company’s laboratories need to be approved by a group of mechanics in real use situations. The practice is inherited from the founder himself, a former mechanic who decided to manufacture his own additives dissatisfied with the ineffectiveness of the options available on the market at the time.

To ensure effectiveness, the company even adopts aggressive marketing strategies. In the case of the Konvertech line, aimed at decontaminating cooling systems, Queiroz keeps an open challenge: he promises an immediate payment of R$ 5 thousand via Pix to any customer who proves that the product, applied correctly, did not work.
With an eye on the modernization of the national fleet, Koube starts 2026 with two strategic launches. The first is the Hybrid and Electric Ready-to-Use Additive, formulated with low electrical conductivity to protect sensitive components such as batteries and inverters. The second is the Organic Concentrated Additive Plus, focused on combustion engines (flex and diesel), which promises to raise the boiling point and prevent cavitation corrosion.
Currently, the brand’s portfolio has more than 150 items divided into eight families, ranging from heavy line and agro to motorcycles, keeping production concentrated in Paraná under strict quality controls.
