Coated paper 

Technological improvement as competitive advantage

Enhancing productivity and quality

Enhancing productivity and quality

The optimization of coating formulations in graphic and packaging paper is a crucial task in modern papermaking. Competition pushes all producers to differentiate themselves and contain costs. Both differentiation and cost optimization must be driven in the direction of a technological improvement so that the competitive advantage is based on added value rather than reduction in quality.

We provide solutions for enhancing productivity and quality of the final products, in a process that exploits our rheology expertise and considers runnability, output optimization, energy demand reduction and paper/board surface characteristics’ improvement.

Product portfolio

Rheology modifiers

Thanks to proprietary technologies, Lamberti offers a full range of natural and synthetic polymers for tailoring the coating color rheology:

Natural polymers

Consciously developed anionic waterborne thickener, our CARBOCEL® CMC is based on natural cellulose with certified sustainable origin representing an entirely ethical solution. These derivatives enhance coating color water retention and contributes in OBA carrying. Based on our long experience we manufacture special grades too for fulfilling specific needs. 

Synthetic polymers

VISCOLAM® are  alkali swellable emulsions (ASE and HASE) engineered for the stabilization and control of coating color rheology. VISCOLAM® thickeners provide rheology and water retention control, coating color’s solids stabilization together with cost effectiveness. Our range of products is specifically designed in order to optimize blade load control and reduce the most common coating defects such as bleeding, misting and orange peel.

Gloss enhancer

LAMLUX is an aqueous emulsion of polyoxyethylenic polymer designed to deflocculate coating pigments and increase final paper gloss and brightness.  


LAMKOTE, our dispersion of calcium stearate, is used as a lubricant to provide good gloss, preventing dusting and fold cracking in paper and paperboard making. It also reduces coefficient of friction under the blade.

Dispersing agents

REOTAN® are acrylic-based dispersing agents designed to deflocculate clay and calcium carbonate particles and to prepare a stable, free-flowing suspension at high solid content. Low to high molecular weight polymers are available.

Pigment dyes

LAMPRINT are dispersed pigment dyes with high light fastness for shading and tinting.


DEFOMEX is a fatty ester based defoaming agent for coating colours and surface treatments.
