New Raw Materials Page

We are glad to announce the new RAW MATERIALS page.
A collection of raw materials which are compatible with cationics and can be used in architectural coatings, will be updated regularly.

Cationyl by PurpurLab

 

Cationyl is a registered brand from the German company PurpurLab. Cationyl is a series of water-based and VOC-free pigment dispersions suited for use with a broad range of cationic formulated coatings that are based both on cationic binding agents as well as on cationic dispersions and emulsions. The Cationyl product line covers the entire color spectrum. Transparent pigments are available as Cationyl pigment preparations for coloring wood and cork surfaces.

Vernis Claessens

Vernis Claessens is one of the few paint manufacturers claiming cationic technology as an asset for their products. Most of their competitors seem to use cationic as a complement for their assortment, but Vernis Claessens seems to make it an specialization. We'll follow their next steps.

How to know whether it is a cationic paint?

There are not too many companies willing to fully communicate they are using cationic technology. In most of the cases cationics are used only to complete their portfolio and are niche products. And this makes marketing does not spend a lot of resources communicating about. Probably one of the few doing some communication on cationics are the Swiss company Vernis Claessens with its brand Classidur (you can see their products in our section about paints).
Switzerland companies are quite weird in terms of communication,, as some of them disclose their recipes even in their website... amazing!

PigaPur IsoPrimer
Bosshard Farben

You can find here the Technical Data Sheet in German:
http://www.bosshard-farben.ch/content/download/307/2692/version/29/file/tm_d_PigaPur_Isoprimer.pdf

Then, here you are the Safety Data Sheet, also in German:
http://www.bosshard-farben.ch/content/download/307/2690/version/29/file/sdb_PigaPur+Isoprimer_51122-010000_DE_0800.pdf
You can see in that SDS, section 9, that pH is acidic, and this is a good indication that we have a cationic product.

Finally, you have the composition in the product declaration the company makes to the Swiss Union of Paint and Ink Manufacturers:
http://www.bosshard-farben.ch/content/download/307/2691/version/29/file/vslf_d_PigaPur_Isoprimer.pdf

23-24 % Acrylic dispersion
  4.70%  Ester
42-43 % Water
 18.00% Titanium dioxide
  0.50% Silicone additive
  0.95% Thickener
  1.00% Wetting agent
  0.25% Defoamer
  5.00% Kaolin
  1.60% Silice oxyde
and MIT:BIT 1:1 100 ppm

Ok, it's not exactly the recipe but you have a clue of what are they doing, isn't?

MFFT - Minimum Film Forming Temperature

M.F.F.T. is the lowest temperature at which a polymer or solid portion of an aqueous polymer dispersion (also called latex or emulsion) self coalesces in the semi dry state to form a continuous polymer film, which in turn acts as a binder for the rest of the solids in the paint film. At temperatures at and above the M.F.F.T. of the polymer the film is formed.

"Coming to Terms: M.F.F.T. = Minimum Film Forming Temperature" is an original publication of Vincentz's European Coatings Journal, 03/2003, p.112. Follow the link:
http://www.european-coatings.com/content/download/61618/712441/version/1/file/45179.pdf

At temperatures below its M.F.F.T. the polymer cannot coalesce to form a continuous film and thus cannot bind together itself (or any pigments and extenders that may be present) and a "cracked, crazed" powdery layer results.
