generally used to bring down the viscosity of paints to the desired level‚ which also reduces the cost of paint formation. They constitute 70%-75% of the paint liquid and ultimate escapes into the atmosphere when the fluid dries. Solvents such as ethylene glycols and alcohols are finding wider use as co-solvents in new water-borne formulations. Binders are generally oils‚ resins and plasticisers that give paints its protective property. Most resin manufacturers make alkyds‚ polyesters‚ emulsion

Should NASA continue to be funded by the U.S government? Remember the “Space Race” against Russia? What would have happened if we had shut down NASA before that? Getting a man to the moon was a Cold War victory! Shutting down funding for space exploration would be utterly devastating. Did you know that we can do research in space that we can’t do on earth? In space‚ we can understand more about gravity‚ and how machines work in different conditions‚ special medical research can be done in space

During the war nylon replaced Asian silk in parachutes. By the 1950s man-made fibres took 20% of the fibre needs with another fibre called Acrylic. Meanwhile another fibre named polyester was invented in Britain by condensation polymerization of ethylene glycol with terephthalic acid. The best thing about polyester is its strength. The suitability of polyester over nylon helped it to occupy 54% of the textile market. So‚ by the 1953 the majority of man-made fibres were discovered. After that some

were treated differently for quality sake. One was by boiling the samples in 100ml denatured alcohol for 1-2 minutes and the other was for 3-5 minutes in100ml water then‚ cooled and strained using a piece of cloth. Add calamansi juice with 25ml ethylene glycol and 15ml phenol for the improvement of quality. Each was evaluated using a rating scale of 1-5‚ having 5 as the most acceptable in terms of color‚ odor and texture. The experiment was observed by the researchers within 14 days and rated

Formaldehyde is known to be one of the most reactive organic compounds. It can be produced by various reactions. It can produced by methods such as: Methanol undergoes an oxidation reaction in the presence of catalysts‚ ethyl-alcohol‚ coal gas‚ ethylene‚ methane‚ glycol‚ glycerin‚ and carbon monoxide Production of formalin form methanol: Formaldehyde is manufactured from methanol and air either by using a silver catalyst or a metal oxide catalyst. Using Silver Catalyst: To convert methanol to
