A number of adhesion promotion methods have been developed to enhance PTFE bond strength. The primary methods currently used in industry are sodium etching and plasma etching. Results of ion beam treatment and laser surface roughening have also been reported in the literature, but do not have a significant presence as commercial processes.
An adhesion barrier is a medical implant that can be used to reduce abnormal internal scarring following surgery by separating the internal tissues and organs while they heal. Surgeons have realized that proper surgical technique is crucial to reduce adhesion formation.
An increased residence time through adhesion to the mucosal surface, such as in the eye or the nose can lead to an improved absorption of the drug. [ citation needed ] Long-duration continuous imaging of diverse organs (via a wearable bioadhesive stretchable high-resolution ultrasound imaging patch, potentially enabling novel diagnostic and ...
Adhesives are typically organized by the method of adhesion followed by reactive or non-reactive, a term which refers to whether the adhesive chemically reacts in order to harden. Alternatively, they can be organized either by their starting physical phase or whether their raw stock is of natural or synthetic origin.
A release agent (also mold release agent, release coating, or mold release coating) is a chemical used to prevent other materials from bonding to surfaces. Release agents aid in processes involving mold release, die-cast release, plastic release, adhesive release, and tire and web release. [ 1 ]
The process is highly regulated by cell adhesion molecules, particularly, the addressin also known as MADCAM1. This antigen is known for its role in tissue-specific adhesion of lymphocytes to high endothelium venules. [23] Through these interactions they play a crucial role in orchestrating circulating lymphocytes.
