DESMOSEAL M 280 is an aromatic prepolymer based on diphenylmethane diisocyanate used as a binder in the formulation of one-component polyurethane sealants. DESMOSEAL M 280 offers medium viscosity and high NCO content which makes it suitable for applications requiring moisture curing properties. As a binder, DESMOSEAL M 280 helps formulate durable and flexible sealants providing long-lasting protection from external elements. Its properties like adhesion, flexibility and weather resistance make the sealants incorporating DESMOSEAL M 280 ideal for sealing and bonding in construction applications.
