Smil-O-Spray is a modified starch possesses no ionic charge. Smil-O-Spray shows consistently excellent strength properties under a variety of kraft paper/board paper machines and paper making conditions. The retention of Smil-O-Spray sprayed in the wet paper web is much higher than that of conventional starches. As a result, BOD and COD of white water are kept at lower levels. Smil-O-Spray granules are entrapped by the fibrous web and subsequently gelatinized by heat available in the dryer section.

The use of Smil-O-Spray in cold water suspension of 1 to 10% solids (by metering pump) and 3 to 5% solids (by spraying method) is recommended to achieve excellent improvement in the paper physicals. However, the dosage levels could be maximized depending on the properties required and quality of paper products.
