Provided are material testing devices and methods for measuring certain physical properties of materials, such as for example, drying, curing, film formation, friction, adhesion, print resistance, and scratch resistance. The testing device includes a platform, a stylus comprising a probe, an angle sensor, a linear position sensor, a control system with a power supply and a control center which may be programmed with testing parameters.

Device for measuring various properties of coatings and materials and methods of using the same

Provided is an apparatus and technique for monitoring the drying, cure, film formation, and viscoelastic properties of liquids, solidifiable liquid films, and the insitu measurement of viscoelastic properties of solidified films.

Device for measuring drying, curing, film formation, and rheological properties of liquids and films

A method for improving holdout on a coated, cellulosic substrate, such as a man-made fiber board. The process comprises the steps of applying an aqueous carboxymethyl cellulose acetate butyrate size composition to a man-made fiber substrate, forming a sized substrate. The sized substrate is then dried. Next, an aqueous coating composition is applied to form a coated, sized substrate. The coated, sized substrate is then dried. According to the invention, the aqueous carboxymethyl cellulose acetate butyrate size composition used in the process comprises carboxymethyl cellulose acetate butyrate, water, and an organic solvent. The invention also relates to a sized, man-made fiber substrate comprising a man-made fiber substrate and a carboxymethyl cellulose acetate butyrate size. The carboxymethyl cellulose acetate butyrate may be either an internal sizing agent, or an external sizing agent.
