New-age Paint Thickening & Rheological Additives : Solvitex & Solvizen

For Paint Suppliers worldwide, there has appear a radical new enhancement in the legion of Thickening Brokers & Colloidal stabilizer for Aqueous Latex Paints. So much most of the businesses producing aqueous Paint emulsions, the most preferred thickening agent was Hydroxy ethyl cellulose (HEC). The HEC based mostly thixotropic additives is produced by some of the renowned multi-nationwide organizations these kinds of as Hercules, Akzo Nobel & Dow.

In this article we refer to a Biopolymer primarily based on Polysacchride derived from managed derivatisation method from plant origin. The merchandise made by Asian Trade Backlink Chemical compounds Division in India has previously been a productive undertaking for substitution of HECs for quite a few paint businesses. The Item is known as Solvitex thickening agent & colloidal stabilizer.

The solvitex range of goods is supplied in extensive array of viscosities of aqueous remedies. It arrives in Powder variety of Offwhite colour and the thickening homes are similar to HEC.

But the Pros of Solviex towards HECs are lots of. The primary aspect is the security & financial pricing. Its been noticed that for a Medium viscosity selection of items such as Natrosol 250 HBR or Bermcoll 381 the initial drop soon after settling is by 20% and then the concluded paint adheres to be secure for 6 months.and the viscosity more drops. Solvitex has an original drop of settling to 10% and the products is secure in bodily observation for far more than 1yr exhibiting the identical viscosity.

As acknowledged by several Paint professionals, its inescapable that the steadiness of thickening agent soon after incorporating in the Paint program, is fragile to vast temperature adjustments. In particular applicable for Export shipments when the Paint underneath goes by numerous temperature ailments all through its transit. A unexpected fall & increase in outdoors temperature can influence the security. Solvitex has most likely demonstrated to be secure beneath these conditions.

Amongst HEC, I individually obtain Cellosize of Dow as the most stable solution in comparison to Bermocoll & Tylose.

Myself as Paint formulator & other colleagues functioning in various corporations had a problem present for selection. For more affordable Paints the More powerful products or Significant Viscosity grades have been employed these but there generally was a flocculation soon after some period of time on shelf storage. For the Highly-priced types we experienced to prefer Medium Viscosities quality to overcome shelf storage time. Most of the businesses carry the similar apply.

When I came throughout Solvitex vary of Thickeners I was specified substantially competitive price ranges. Priced at minimum 10% lower than HEC primarily based Solutions, but my significant problem was to test the colloidal stabilization. The Product was right away tested and was discovered to execute great.

Apart from that, Solvitex has supplied better colour acceptance & and coatabilty.

Sooner we came across Solvizen created by the exact same corporation for additional financial & much less expensive Value. The thickening & security attributes was the similar but economically priced.

Having said that, The Water answer clarity of Solvizen was not as crystal clear as of Solvitex or HECs. It was slight turbid. But when included in Paints, we could not come across any distinction. Once more the Paint was secure physically observed.

As a Paint formulator from past 2 a long time and based mostly on my encounters, I propose to all people experts in the same field to attempt Solvitex & Solvizen array of Thickening brokers.
