Diamine OLBS is produced by Akzo Nobel Surface Chemistry an active adhesion promoter for hot bitumen, cut back bitumens, soft bitumens and emulsions used in surface dressing (chipseal), and cold and warm mixes, including those using reclaimed materials. It is a liquid product for excellent active adhesion in chipseal and soft bitumen mixes

Benefits and Features

• Active adhesion: Treated bitumen has the ability to displace water and finds use in spray applications whenever the aggregate could be wet or in mix operations at lower temperatures.
• Easy to use: The product has significantly lower viscosity than other concentrated adhesion promoters, even in cool temperatures, making for easy dosing.
• Patch mix: The excellent active adhesion of the product makes it the best choice for patch mixes based on cut back and fluxed bitumens.
• Emulsion quality: The quality of cationic rapid and medium setting emulsions is improved by the addition of Diamine OLBS to the bitumen
