The growing concern with sustainability has led to numerous developments in the paper industry, for example the replacement of plastic film as a waterproofing barrier.

In this trend, Mark has developed the Topping™ Line, with technology that promotes uniform paper coating to provide the necessary barrier to water, vapors, or oil.

Meeting different demands, the Topping™ Line is composed of products formulated from synthetic, vegetable, and mineral raw materials, following the sustainable trend. Relying on a new polymerization concept, associated with high performance additives, the Topping™ Line allows the desired level of waterproofing to be obtained, according to the end use of the paper.

Versatile, the Topping™ Line waterproofing resins can be sized for use in both on and off-line application systems, providing high operational performance and an excellent cost-per-ton produced ratio.
