NM 791 is an epoxy-based, two-component, solvent-free, elastic jointing compound. NM 791 is elastomeric and does not become brittle even at low temperatures. Adheres well to most materials.
Surfaces and joints requiring high resistance to mechanical and chemical weathering.
Base seals with closed surface structures should also be used in joints.
NM 791 should be used if contact with chemical agents is constant.
