Unlock the full potential of your bitumen applications with A S Harrison & Co’s comprehensive range of cutting-edge bitumen additives. Our meticulously crafted additives cater to diverse applications, enhancing crucial aspects such as adhesion, viscosity, and environmental sustainability.
Explore our Adhesion Promoters, integral for extending the service life of roads by fortifying the bond between aggregate and bitumen. These additives not only enhance adhesion but also boost hardness, soften points, and improve deformation resistance.
Discover the versatility of Bitumen Emulsifiers, including both amphoteric and cationic varieties, providing efficiency in overheated and cutback forms. Emulsifying bitumen not only reduces viscosity without constant heating but also introduces eco-friendly benefits, minimising Volatile Organic Carbon (VOC) and lowering storage and transportation costs.
Discover the applications of Amphoteric Emulsifiers, ideal for stable emulsions in low temperatures and compatible with cold, damp aggregates. Explore the dynamic range of Cationic Emulsifiers, featuring Cationic Rapid Setting emulsifiers (CRS) for quick reactions with aggregates and Cationic Slow Setting Emulsifiers (CSS) for maximum mixing stability.
Elevate road construction with our Crumb Rubber Additive, a patented blend of polyoctenamer and ground tire rubber. Derived from innovative rubber recycling, Vestenamer® forms a durable, non-sticky binder for asphalt, improving road longevity, resistance to heavy traffic, and efficiency in preventative maintenance
Revolutionise your asphalt performance with our Viscosity Modifiers, designed to lower viscosity in warm mix asphalt, enhance hardness, soften points, and elevate deformation resistance. Elevate your bitumen projects with A S Harrison & Co’s transformative additives, setting the benchmark for excellence in the industry.
Product and customer insights
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
The East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
