Liquid Seal 300DP introduces an innovative sealing technology developed in Germany. This one-component liquid sealant is specifically designed to completely seal tiny holes, such as hairline cracks and pinholes of 0.1 mm or less, which often occur in castings and welds. By simply applying it, Liquid Seal penetrates deep into these small holes through capillary action, effectively plugging leaks. No special equipment is required, making it easy to use and highly efficient. As a result, Liquid Seal 300DP offers a convenient, reliable solution for sealing leaks, ensuring durability and preventing further damage without complicated procedures.
