Lansperse RPS43

Product Category: Coatings Additives

Biobased Dispersing Agent

Quick Links

Lansperse RPS43 is one of our new rapeseed biobased range of products, and is the last one in this particular series. Lansperse RPS43 is the most hydrophilic one as shown by its HLB value. Rapeseed is a good sustainable crop with no environmental concerns. These are based on our proprietary BioLoop technology in which two hydrophobes attach to particle surfaces to stabilise the dispersing action.
