Materials which is required to produce an correction pen?
Answers
Answer:
A correction fluid or white-out is an opaque, usually white, fluid applied to paper to mask errors in text. Once dried, it can be written over. It is typically packaged in small transparent bottles, and the lid has an attached brush (or a triangular piece of foam) which dips into the bottle. The brush is used to apply the fluid onto the paper. It can be used for many purposes.
Before the invention of word processors, correction fluid greatly facilitated the production of typewritten documents.
One of the first forms of correction fluid was invented in 1956 by the secretary Bette Nesmith Graham, founder of Liquid Paper.[1]
With the advent of coloured paper stocks for office/typing/photocopier/calender use, correction fluid manufacturers began producing their product in various colours, particularly reds, blues, and yellows, so that corrections made on these papers would be less visually invasive
Answer:
The exact composition of correction fluid varies between manufacturers, but most fluids are composed of an opacifying agent, a solvent (or thinner) and an adulterant 'fragrance' to discourage abuse. The opacifying agent can be composed of a mixture of titanium dioxide, latex, and other polymer resins.
