Features

Liquid Seal 300M is an innovative sealing technology developed in Germany that offers an advanced solution for sealing small leaks. This one-component liquid sealant is designed to completely seal tiny holes (such as hairline cracks and pinholes) ranging from 0.1 to 0.5 mm, commonly found in castings and welds. By simply applying the sealant, it penetrates deep into the tiny holes through capillary action, ensuring a tight and secure seal.

What makes Liquid Seal 300M especially effective is its ease of use—no special equipment is required. It works just like Liquid Seal airtight sealants but with improved continuous heat resistance compared to the conventional Liquid Seal WF-Macro. As a result, users can achieve more reliable and long-lasting seals in their applications, providing an efficient solution for plugging leaks in a variety of settings.
