In the production c>f base papers for silicone coating, one of the most important variables is the holdout capability of the ' base sheet. The holdout is primarily affected by the surface characteristics of the sheet relating to the smoothness and surface structure.
An experiment was designed to look at the effects of several different commercial film forming agents in a standard size solution on the holdout properties of the sheet. A laboratory size press coater was assembled and used for application of the size solutions. After supercalendering, the sheets were silicone coated with an aqueous silicone solution and then tested for release properties.
Results show that CMC and Kelgin provide the best release properties. By evaluation of both physical and financial properties, the use of CMC would be recommended.
