About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

Product description of the manufacturer

TECPO windscreen adhesive is a high-quality product that has been specially developed for fixing car windscreens. In terms of adhesive strength, the product can be rated as excellent, with reliable adhesion guaranteed even under extreme conditions. In addition to its strong adhesion, the adhesive is characterised by its long durability and is resistant to water and other environmental influences. Due to its elasticity, the adhesive is equally suitable for professional applications and for use in the hobby sector. The use of this adhesive helps to minimise the risk of stress cracks and ensures an optimum bond between the pane and frame. In addition to these technical properties, the product impresses with its ease of use and consistent quality with every application.

  • Strong adhesion
  • Water resistant
  • Easy handling
  • Very small font on the tube

The packaging of the TECPO windscreen adhesive creates a mixed first impression. The colour scheme is clear and reduced to the essentials, clearly highlighting the key product information. At first glance, the packaging conveys an impression of robustness and high-quality workmanship, which emphasises the quality of the product. The adhesive is packaged in a user-friendly cartridge that enables precise and clean dispensing. In addition to the adhesive itself, clear instructions are included on the tube, which are easy to understand even for inexperienced users. Unfortunately, however, the font is too small. Overall, the packaging gives a professional impression that inspires confidence in the quality of the product.

The application of TECPO windscreen adhesive is consistently convincing. During application, the adhesive presents itself as a homogeneous mass that enables even distribution. Even after curing, the adhesive is highly elastic, allowing it to adapt to different material movements. In addition, the easy visibility of the adhesive after application contributes to an aesthetic result. No unsightly residues or stains are left behind, which contributes to a clean and professional finish. The sophisticated composition of the product facilitates application and ensures an optimal end result.
