Process
Porosity sealing is a four step process:
- Air within the pores is expanded under reduced pressure (vacuum).
- Pressure reversal (adding pressure outside the part) saturates pores with monomer.
- Excess monomer is rinsed from the exterior surfaces of the part.
- The liquid monomer within the porosity is polymerized into a solid to seal the passage.

Famous quotes containing the word process:
“Interior design is a travesty of the architectural process and a frightening condemnation of the credulity, helplessness and gullibility of the most formidable consumers—the rich.”

“Experiences in order to be educative must lead out into an expanding world of subject matter, a subject matter of facts or information and of ideas. This condition is satisfied only as the educator views teaching and learning as a continuous process of reconstruction of experience.”
—John Dewey (1859–1952)
“Any balance we achieve between adult and parental identities, between children’s and our own needs, works only for a time—because, as one father says, “It’s a new ball game just about every week.” So we are always in the process of learning to be parents.”
