Innovative VAcA binder


Does your paper need a little push? Is your board missing some boost?
- You’ve come to the right place. VAcA binder gives you plenty of new, exciting things to take you to that next level.

Liquorice, anyone?

Fulfilling market’s needs by adjusting coating

The interest towards newly developed VAcA binder has increased rapidly as the industry is seeking new opportunities in a dynamic market environment. In today’s market place the traditional coated paper or board product needs to fulfill several new requirements coming for instance from converters, brand owners, end-users or regulators. In order to meet these needs in a cost-effective way, the manufactures are looking at their coating formulations. The mindset is clear: minimize the changes from the current status quo, but maximize the value added.  In other words, coated paper and board producers are looking for a simple solution that allows them to broaden the business potential of their existing products. VAcA binder is a perfect solution for this approach.


VAcA and the special features

What makes VAcA special compared to traditional binders such as SB and SA is the hydrophilic character and its ability to create a specific pore structure. These features are created by the VAM monomer that is polymerized into VAcA together with Acrylate monomer using newly developed CH Polymers technology. Thanks to this Next-Gen polymerization technology the dispersion is very stable and particle size is kept small.


Remarkable properties for coated paper and board

The unique properties of VAcA binder can be seen in superior wet and dry strengths, but also as improved brightness and more bluish shade of the paper/board. By controlling the pore structure of the VAcA coating, the ink setting can be adjusted or alternatively the offset printed paper can be used for other printing methods where a high void volume of coated paper is important to ensure a good ink drying,  as an example in inkjet or flexo printing. Also the controlled pore structure allows optimization in coating pigment selection. For packaging paper and board the VAcA binder gives a very high UV-varnished gloss and superior PE adhesion. In commercial scale trials it has been also noted that VAcA coating improves the paper profiles by enhanced rheology and interestingly the on-machine drying energy could be reduced by 10 – 15 %.


The bottom line

But what does all this tech-talk mean for the bottom line? Well, simply put, it means that the VAcA binder is a great tool in adding value to your coated paper or board. Reade more about our case studies to learn how to leverage on VAcA and CH Polymer’s knowhow.

“Via VAcA binder we are doing our part in the forest industry renaissance. Printed communications are not going anywhere and with our VAcA binder the image quality is our competitive edge. We want to offer our extensive knowledge in polymer chemistry and binder application to our customers – and believe that we can be a valuable partner to the customer’s product development team.”

Barrier Coatings


Feel like you hit a wall dealing with all those industry rules and restrictions?
- Let us tell you how water-based Barrier Coatings can get you out of a jam!  

Sustainable solutions

Forest industry faces increasing restrictions set by different authorities. New statutes for packaging material and waste, taxes for plastics, arguments for more sustainable and safer products and consumers’ preference for “green” products have set the packaging industry on a quest for new solutions. CH-Polymers helps the packaging industry to develop sustainable solutions for a changing marketplace.


Environmental solution

Today, the most commonly used barriers in packaging industry are PE-plastics, wax and different fluorochemicals. Water Based Barrier Coatings (WBBC) can be used as a more environmental solution to replace PE, Wax and Fluorochemicals in several application areas, where the need for absolute barrier properties is not essential.


Possible application areas

The barrier properties of the WBBC can be modified, achieving, as a consequence, good grease resistance, moisture and water resistance as well as oxygen barrier. Possible application areas for WBBC products include, for example, ream and reel wraps, fast food packages, frozen food packages, cereal boxes, salt, sugar and flour packages.


Recyclable and compostable

CH-Polymers has a long history and excellent knowledge in developing recyclable and compostable water-based barrier dispersions. With the help of various R&D Centers, universities and brand owners, we are constantly working to come up with cutting-edge sustainable solutions – all targeted to help our customers better meet the new environmental statutes and laws.


“The market is developing fast and the global packaging industry has great need of these products. With our broad experience from the field, supported by fast and focused product development, we can react according to market needs quickly and deliver the solutions that benefit the most.”

New Emulsion Polymers


Just when you thought you’d seen it all in the field of emulsion polymers…look out, here come the New Emulsion Polymers!

Game changer

We firmly believe that New Emulsion Polymers (NEP) represent a real game-changer.  But what is NEP all about? - Through hundreds of laboratory synthesis, piloting and application testing we have been able to develop a revolutionary way of producing value added binders and additives: New Emulsion Polymers.

Versatile functionalities

With the NEP technology, we can create versatile functionalities out of various new raw material sources. We can, for instance, take the environmental approach and utilize biostreams – or we can design a cost-effective binder that minimizes raw material cost fluctuations.


Endless possibilities

Under the NEP concept, it is also possible to produce functional binders that improve hydrophobicity, PE adhesion, barrier properties or 2D/QR code readability... With the NEP approach, the possibilities – and the inherent commercial potential – are quite endless.
