Fine-tuning the characteristics of water-borne paint

 

Bermocoll in latex paint

We at AkzoNobel have been serving the paint industry for more than 50 years with Bermocoll, a range of non-ionic cellulose ethers. Bermocoll is used as a thickener, stabilizer and water retaining agent for water-based decorative paints.

When we make Bermocoll the cellulose reacts with substituents, such as methyl, ethyl and hydroxyethyl or hydrophobic groups. This process, called etherfication, makes Bermocoll water soluble.

Bermocoll for latex paint:

• E grades are ethyl hydroxyethyl cellulose
• EM grade is a ethyl methyl hydroxyethyl cellulose ether, and is a high  efficiency thickener
• EBS and EBM grades are resistant against enzymatic attack
• EHM grades are hydrophobically modified EHEC and are resistant against enzymatic attack

Bermocoll cellulose ethers can be regarded as polymeric surface active agents. They can contribute to dispersion of pigments by improving the flow during grinding.

We produce Bermocoll in wide range of viscosities in order to enable our customers to choose the  required application viscosity of the paint. 

We want to avoid the lump formation that can occur when Bermocoll is added to water. That is why we treat all paint grades of  Bermocoll with controlled amounts of glyoxal.

Bermocoll is used in textured paint, chemical plaster, flat paint, satin paint and semi-gloss paint.

Bermodol additives are polyurethane- or surfactants-based and can be used  to modify rheological properties in paint and aid in dispersing pigments.

Please, welcome to join us in the world of  Bermocoll  and Bermodol – it can make a difference.
