Polubutene improves the durability and ageing of undercoats based on rubber or hydrocarbon resins and can provide waterproofing protection to permeable substrates like concrete and wood.
| Product | Description | Benefits | Applications |
|---|---|---|---|
| Polubutene | Conventional Polybutene is a liquid polymers with an average of 250 to 2,500 molecular weight, with isobutylene as the main structure. | Colourless/odourless. Excellent chemical stability against heat, reagents and UV. Easy to store due to no coagulation or vaporisation. High solubility in kerosene, coal tar, aromatic compounds, hydrogen carbonate, lubricating oil. | Formulation of various types of adhesives such as Pressure Sensitive Adhesive (PSA) and Hot Melt Adhesive (HMA). Low temperature flexibility, waterproof, tackiness in the case of asphalt sheet. Dispersing agent for the pigments, inks, assistant material of foaming agent of synthetic resin including polystyrene, polyethylene and polypropylene. |

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.
