Welcome to Namtvedt Group - Company History

Through Namtvedt Sealmaker Services AS we have over a short period of time become one of the leading Differentially Activated Sealant Technology Company in Europe together with our partner Sealmaker International Inc. Sealmaker sealants are engineered to remain liquid and inert until exposed to pressure differential and positive displacement through a point of convergent flow.
