The ratio is 1:4 (1kg Smil-o-Cold to 4 litres of Water). Take water in a container and stir it with a stirrer at 900-rpm. While the stirring is in progress, add Smil-o-Cold gradually into the vertex of water formed by stirrer
The Smil-o-cold to water ratio may however, be changed to ensure required viscosity depending on the gsm, quality of paper and single facer or double backer bonding. |
