Applications:
OraRez® MS is an outstanding oral mucosal adhesive suitable for denture adhesive formulations. The ionic bridges inside the OraRez® MS molecule results in both adhesive and cohesive adhesion to generate long lasting and durable oral denture adhesive systems. OraRez® MS acts as an adhesive cushion between the denture and gums to strongly adhere the denture to the gums and reduce the likelihood for irritation due to a loose fitting denture. The use of OraRez® MS based denture adhesives is an essential component for obtaining natural and comfortable feeling dentures.
