Escat® range of catalysts can be used to enhance reactivity in all major powder coating chemistries. The products are supplied as either 100% active or adsorbed onto a carrier via Estron’s proprietary adsorption process
| Product | Description | Benefits | Applications |
|---|---|---|---|
| Escat® ST-70 | Escat ST-70 is the tin-based liquid catalyst stannous octoate adsorbed onto a silica carrier. | Escat ST-70 is incorporated as a raw material during the premix stage of processing. Typical dosage ranges from 0.1 – 1% based on total formula weight. | The additive may be used in both e-caprolactam blocked polyurethane powder coatings and the internally blocked uretdione systems. |
| Escat® BT-71 | Escat BT-71 is a tin-based catalyst comprised of dibutyltin dilaurate adsorbed onto a silica carrier. T | Escat BT-71 is incorporated as a raw material during the premix stage of processing, and a laboratory investigation is recommended to optimise the concentration and processing conditions for a particular formulation. Typical dosage ranges from 0.1 – 1% based on total formula weight. | This product may be used in both e-caprolactam blocked polyurethane powder coatings and internally blocked uretdione systems. |
| Escat® 124 | ESCAT 124 is a Tetrabutyl Ammonium Bromide combined with inorganic carrier. | Escat 124 is highly reactive catalyst | The product is used to accelerate the cure of powder coatings as polyester-epoxy, carboxyl acrylic-epoxy, polyesters cured by GMA-functional acrylics, polyester-TGIC and polyester-PT-910. |
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.
