Sikaflex 221 is for sealing applications in automotive, transportation, Wind, Solar industry.
This application is successfully executed for sealing of a cable joint in an electric motor of a giant industrial fan. In many end use these fans are used in outdoor areas or in locations where rain water can come into contact through roof holes. It was found that water would generally find its way through the cable groove and seep inside the motor windings causing malfunction. The problem is resolved by a slight modification in design and using Sikaflex 221 Polyurethane sealant.
