Product description of the manufacturer
The product silicone sealant from the TEPCO brand is a silicone sealant.
The versatility of this product makes it an ideal solution for elastic bonding and sealing in bus, train and vehicle construction. It is ideal for a wide range of materials, including metal, plastic, glass, ceramics and wood. This flexibility enables a wide range of applications to meet the requirements of a wide variety of projects.
An outstanding feature is its extreme temperature resistance. Once cured, the product remains elastic and stable, even at extreme temperatures from -40°C to +260°C. This property ensures reliable performance under demanding conditions, which is particularly important in the automotive industry.
In addition, the product offers long-lasting protection. It is UV-resistant, climate-resistant and resistant to water, salt water, oil, coolant and many chemicals. This robustness ensures that the bonds and seals retain their functionality even under adverse conditions.
Precise and efficient processing is supported by the high viscosity of the product, which makes it easy to handle . It bridges large sealing gaps and reliably fills unevenness , making application considerably easier.
In the practical test, this product impressed with its ease of use and good silicone quality.
Advantages
- Easy to use
- Good curing, but still retains elasticity
- UV-resistant, climate-resistant, hard-wearing
Disadvantages
- Some practice is required for even application
The first impression
Packaging and contents
Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

This product was delivered in a product box that was well matched to the size of the carton.
A positive aspect to emphasise is the fact that no environmentally harmful materials were used in the packaging.
The product does not come with separate instructions for use, but relevant instructions for use can be found on the surface of the bottle.

When you pick up the product for the first time, you immediately notice its pleasant size. The bottle sits comfortably in the hand and can also be easily used by people with smaller hands.
The first thing that catches the eye on the outside is the clear step-by-step instructions for use.
The cap fits tightly and is well sized. It can be pulled off with a little effort, but is not too loose to come off easily.
Overall, the sealing bottle makes a solid and stable first impression.

The silicone seal was subjected to extensive practical testing.
In terms of adhesion, the tests showed that the silicone is suitable for a wide range of materials such as wood, glass, plastic and ceramic. After the drying process, a slightly elastic, very well adhering black mass was created.
The heat and cold resistance was particularly evident when exposed to sunlight and sub-zero temperatures overnight. No weaknesses in the material could be recognised here.
A minimal odour was noticeable when applying from the bottle, but this dissipated fairly quickly.
The resistance of the silicone to various cleaning agents was also tested. The material proved to be very resistant and showed no weaknesses.
In the practical test, this product impressed with its easy handling (uncomplicated application after a little practice) and the hard-wearing silicone.

At the time of testing, the product had not been listed on Amazon for long enough. Therefore, the existing reviews do not sufficiently reflect the advantages and disadvantages of the product, so this point is neglected in the evaluation.
Prices of up to €25.00 are charged on the Internet for equivalent products. Very cheap products are available from as little as €11.00 . The silicone seal from TECPO is therefore currently in the middle price segment with a price of €16.99. For the quality and performance received, the price-performance ratio is very good.
