Wax compositions are provided with improved properties for various applications, such as coating of composite cellulosic materials, e.g., composite wood material, more specifically oriented strand board. As described herein, wax compositions include a kinematic viscosity measured at 100&#xb0; C. of &#x2264;13.1 mm/s; and a contact angle on glass of &#x2264;34.4&#xb0;, which provide enhanced water proofing properties. The wax composition may have a flash point of greater than 450&#xb0; F. Wax composition are provided with improved properties for candle jars. As described herein, candle jar wax compositions include 150N foots oil and 600N slack wax. The wax composition can include up to about 80% 150N foots oil.

Coating compositions for oriented strand boards and associated methods of use

Wax compositions are provided with improved properties for various applications, such as coating of corrugated cardboard or other cellulosic paper materials. As described herein, paraffin waxes having a very broad molecular weight distribution are provided, e.g., 95% carbon number spread of at least 18 carbon atoms, which result in wax compositions with a relatively hard needle penetration value, suitable blend kinematic viscosity, and provide equivalent or better wet strength and water proofing properties as compared to waxes currently commercially used in corrugated coating. The paraffin wax compositions described herein also provide a higher congealing point, thereby benefiting the high temperature properties such as oil bleed, appearance and friction coefficient of the corrugating wax coating.

Saturating wax coating composition and associated methods of use

Wax compositions are provided with improved properties for various applications, such as coating of composite cellulosic materials, e.g., composite wood material, particleboard, medium density fiberboard, construction board or combination thereof. As described herein, paraffin wax compositions are provided that have n-paraffin content of from about 30% wt to about 95% wt, and a 95% carbon number spread of from about 1 carbon atoms to about 23 carbon atoms, which provide enhanced water proofing properties as compared to waxes currently used.

Wax coating and associated methods of use

Wax compositions are provided with improved properties for various applications, such as coating of corrugated cardboard or other cellulosic paper materials. In addition to wax, the compositions include a polymer with a hydrophobic backbone that is 'functionalized' to incorporate a limited percentage of hydrophilic and/or polar groups. The compositions can optionally also include inorganic nanoparticles such as clay particles.
