New paint thickener and rheological components: Solvitex & Solvizen

For Paint Producers worldwide, a radical new improvement has arrived within the legion of thickening brokers and colloidal stabilizers for water-based latex paints. Till now, a lot of the corporations that produced aqueous emulsion Paint, essentially the most most well-liked thickening agent was Hydroxy Ethyl Cellulose (HEC). HEC based mostly thixotropic components are manufactured by a number of the well-known multinational corporations like Hercules, Akzo Nobel & Dow.

Right here we confer with a polysaccharide-based biopolymer derived from the managed derivatization technique of plant origin. The product developed by Asian Commerce Hyperlink Chemical substances Division in India has already been a profitable HEC substitute enterprise for a lot of paint corporations. The product is called Solvitex thickening agent and colloid stabilizer.

The solvitex product vary is offered in a variety of aqueous answer viscosities. It is available in off-white powder kind and the thickening properties are much like HEC.

However some great benefits of Solviex in opposition to HECs are many. The principle issue is stability and financial value. It has been noticed that for a spread of medium viscosity merchandise equivalent to Natrosol 250 HBR or Bermcoll 381, the preliminary shrinkage after softening is 20% after which the completed paint adheres to stay secure for six months. and the viscosity drops additional. Solvitex has an preliminary settling drop of 10% and the product is secure beneath bodily remark for greater than 1 12 months displaying the identical viscosity.

As many Paint technicians know, it’s inevitable that the steadiness of the thickening agent after incorporation into the Paint system shall be delicate to vast temperature variations. Particularly relevant for export shipments when the Paint goes via totally different temperature situations throughout its transit. A sudden drop and rise in outdoors temperature can have an effect on stability. Solvitex has confirmed probably secure beneath these situations.

Amongst HEC, I personally discover Cellosize of Dow to be essentially the most sturdy product in comparison with Bermocoll & Tylose.

As a paint formulator and different colleagues working in numerous corporations I had a dilemma in regards to the choice. For cheaper colours, stronger product or excessive viscosity grades had been used as such, however there was at all times a flocculation after a sure interval of storage on the shelf. For the costly ones we should always have most well-liked the medium viscosity class to beat the shelf life. Most corporations have the identical observe.

After I got here throughout the Solvitex vary of Thickeners I used to be given very aggressive costs. Priced no less than 10% decrease than HEC based mostly merchandise, however my predominant concern was to manage the colloidal stabilization. The product was instantly examined and located to work nice.

As well as, Solvitex has offered higher shade acceptance and functionality.

We quickly got here throughout Solvizen developed by the identical firm for a extra economical and cheaper value. The thickening and sturdiness traits had been the identical, however at a cost-effective value.

Nonetheless, the readability of the aqueous answer of Solvizen was not as clear as that of Solvitex or HECs. It was a little bit of a blur. However when included in Paints, we could not discover any distinction. Once more the ink was noticed to be bodily secure.

As a paint formulator from final 2 many years and based mostly on my experiences, I counsel all these technicians in the identical area to strive Solvitex & Solvizen vary of thickening brokers.
