For Paint Producers globally, there has arrive a radical new enhancement in the legion of Thickening Agents &ampampampamp#038 Colloidal stabilizer for Aqueous Latex Paints. So far most of the businesses generating aqueous Paint emulsions, the most favored thickening agent was Hydroxy ethyl cellulose (HEC). The HEC mainly primarily based thixotropic additives is produced by some of the nicely-known multi-nationwide businesses this kind of as Hercules, Akzo Nobel &ampampampamp#038 Dow.

Right here we refer to a Biopolymer mainly primarily based on Polysacchride derived from managed derivatisation process from plant origin. The merchandise produced by Asian Trade Hyperlink Chemical substances Division in India has presently been a efficient enterprise for substitute of HECs for a number of paint businesses. The Item is acknowledged as Solvitex thickening agent &ampampampamp#038 colloidal stabilizer.

The solvitex variety of products is supplied in broad variety of viscosities of aqueous choices. It arrives in Powder kind of Offwhite colour and the thickening attributes are comparable to HEC.

But the Benefits of Solviex in opposition to HECs are a number of. The prime element is the stability &ampampampamp#038 financial pricing. Its been observed that for a Medium viscosity variety of products this kind of as Natrosol 250 HBR or Bermcoll 381 the intial drop subsequent settling is by 20% and then the completed paint adheres to be constant for 6 months.and the viscosity additional drops. Solvitex has an first drop of settling to 10% and the merchandise is constant in bodily observation for a great deal a a lot more than 1year exhibiting the exact same viscosity.

As acknowledged by a number of Paint technicians, its unavoidable that the stability of thickening agent subsequent incorporating in the Paint technique, is fragile in the path of broad temperature modifications. Especially applicable for Export shipments when the Paint beneath goes by way of various temperature circumstances all through its transit. A sudden drop &ampampampamp#038 rise in outside temperature can influence the stability. Solvitex has most likely confirmed to be constant beneath these circumstances.

Among HEC, I personally discover Cellosize of Dow as the most constant merchandise in contrast to Bermocoll &ampampampamp#038 Tylose.

Myself as Paint formulator &ampampampamp#038 other colleagues running in various businesses had a issue current for choice. For a lot much less expensive Paints the More potent merchandise or Greater Viscosity grades had been utilized this kind of but there usually was a flocculation subsequent some time time time period on shelf storage. For the Costly ones we had to choose Medium Viscosities grade to conquer shelf storage time. Most of the businesses have the exact same practice.

When I arrived across Solvitex variety of Thickeners I was supplied a great deal aggressive expenditures. Priced at minimal 10% decrease than HEC mainly primarily based Products, but my primary problem was to seem at the colloidal stabilization. The Item was instantly examined and was found to have out excellent.

Apart from that, Solvitex has supplied a a a lot better colour acceptance &ampampampamp#038 and coatabilty.

Quicker we arrived across Solvizen produced by the exact same business for a great deal a a lot more financial &ampampampamp#038 a lot much less expensive Cost. The thickening &ampampampamp#038 stability attributes was the exact same but economically priced.

Nevertheless, The H2o answer clarity of Solvizen was not as apparent as of Solvitex or HECs. It was slight turbid. But when integrated in Paints, we could not discover any distinction. As quickly as a a lot more the Paint was constant physically observed.

As a Paint formulator from prior two decades and mainly primarily based on my experiences, I suggest to all these technicians in the exact same region to attempt Solvitex &ampampampamp#038 Solvizen variety of Thickening agents.
