These include: • Joint sealants for construction and glazing joints, silicone   sealants, acrylate sealants, (one-component and   two-component polyurethane sealants) • Joint sealants for floor joints as well as for sealing drain   pipes (one-component and two-component polyurethane   sealants and polysulphide sealants) The following list summarizes the most important tests that help to evaluate the efficiency of joint sealants and to classify them: Adhesiveness and elasticity, tensile strength, loss of volume and mass, resilience capacity, creep resistance, processability, weather resistance. The sealants are either stored in a variety of storing liquids before they are tested or they are tested under different climatic conditions as it is appropriate according to the specifications of the test standards and regulations.
