Dennison Standard Test Wax Sticks

About Dennison Standard Test Wax Sticks

DESCRIPTION:                     

Dennison paper testing waxes are designed for use by paper and coated paper manufacturers, printers, lithographers, and other concerned with the development, inspection and control of paper for coating and printing purposes.

Dennison Standard Test Wax Sticks are used for determining the resistance to surface pick of paper and board.

APPLICATION:

The integrity of a paper or board surface depends both on the characteristics of the fibre matrix and those of the applied printing inks. The coating must have the correct ratio of pigment and binder to correlate both with the base paper quality to ensure strong adhesion with desired finish to the product. The degree of adhesion and hence surface integrity maintained under conditions imposed by subsequent drying, calendaring and printing operations is widely measured with Dennison waxes.

TEST DESCRIPTION:

The Dennison wax set consists of a series of hard resin, non-oily waxes with graded degrees of adhesion. In operation, the appropriate wax is softened over a spirit lamp and pressed onto the test piece held in place with a hollow wooden block. After cooling, the wax is pulled vertically from the sheet and the surfaces inspected. The test is repeated using the waxes in numerical order until the sample surface blisters, breaks, picks or lifts. The samples may be graded in terms of the critical wax strength numbers which is the highest number of wax stick that does not disturb the surface of the sample.
