- Application
Clear Sizing Paper Because of their excellent water holding and film forming properties, ETHYLEX starches are highly recommended for surface sizing papers. Availability in a wide viscosity range permits their usage at the size press or calender stack; ETHYLEX films give papers better surface strength and hold out properties than those provided by other starches commonly used. As a result, ETHYLEX starches are products of choice for surface sizing fine quality papers. The properties of film clarity and continuity permit the use of ETHYLEX starches in transparentizing papers. In these, and other applications, the thinner ETHYLEX starches - 2015 can be used in the high solids range of 15 to 20%. Their stability and the minimal retrogradation which they exhibit enhance their value in this type of application. Size Press Paper Coating EHTYLEX starches provide process advantages such as viscosity stability and improved runnability to metered size presses. These advantages are not seen in other starches. ETHYLEX starches are especially useful as co-binders in both clear and pigmented surface sizes in conjunction with synthetic resins, polyvinyl alcohol, latexes and other film formers. Hydroxyethylated starches are fully compatible with these materials, and act with them to contribute to the barrier properties that impede the migration of moisture, wax, lacquer and varnish. Paper Coating Certain grades of coated paper, such as label paper, require especially high print quality. ETHYLEX starches are used in these high-solids, pigment-binder systems because they possess unusually high adhesive strengths and provide good compatibility with latex. The ETHYLEX starches also contribute water holding ability, viscosity stability, and consistent rheological properties to coating mixtures. The trend to increased coating speeds necessitates the consistent, stable viscosities of ETHYLEX starches.
