Pdms treatment with silane and glutaraldehyde
Splet18. maj 2024 · Abstract. Three-dimensional (3D)-printing techniques such as stereolithography (SLA) are currently gaining momentum for the production of miniaturized analytical devices and molds for soft lithography. However, most commercially available SLA resins inhibit polydimethylsiloxane (PDMS) curing, impeding reliable replication of … Splet02. jan. 2016 · 9. Polydimethylsiloxane (PDMS) is the main ingredient in Rain-X, a treatment that adheres to windshields. How does PDMS adhere to class? It can't form covalent Si-O bonds with glass, according to one source. Makes sense, as the Si is already coordinated with four groups in PDMS and none of them seem to be easily removable.
