Two coatings were developed for the intended purpose of maintaining steel sheet pile at the waterfront. The new splash zone coatings are free of VOC’s and HAP’s thereby providing a more environmentally friendly alternative to the standard coal tar epoxy system. The new coatings are also more abrasion and impact resistant and applied at more than twice the thickness of coal tar epoxy. All of these factors add up to an anticipated service life of 3 to 4 times that of coal tar epoxy leading to reduced life cycle costs.
BASF has developed a novel crosslinking isocyanate-free coating technology based on carbodiimide chemistry. A polycarbodiimide crosslinker with suitable functionality for coating applications and ultra-low free monomeric isocyanate has been introduced to the market. We formulated a 60% solids industrial primer using the new isocyanate-free coating technology and applied it on different metal substrates.
Seawater biofouling is a major threat in heat exchanger operations. It decreases the heat transfer efficiency and service life of heat exchangers1,2. The formation of deposits caused by biofouling on the heat exchanger metal surfaces increases surface roughness and decreases cross-sectional flow area, which leads to higher friction loss in fluid flow3,4. Mitigation methods, including surface scrubbing, fluidizing bed heat exchangers, cleaning-in-place and dosing anti-fouling chemicals, are the main ways to tackle biofouling5. Conventional approaches to treat biofouled components by periodic electrochlorination or acid flushes are costly and environmentally hazardous. Huge costs are associated with heat exchanger biofouling losses, but there is still a lack of research to develop heat-conducting antifouling coatings to heat exchangers3.
Saline Water Conversion Corporation (SWCC) is the largest producer of water by its different water desalination plants distributed around the kingdom. In SWCC above storage tanks (ASTs) have the capacity to store 140,000 m3 of produced water. Most tanks are commissioned more than 20 years and have worked properly with minor observations on their performance. Mostly SWCC tanks are made of carbon steel and internally protected with a two - components epoxy coating as a passive method and cathodic protection as an active method.
Pacific Northwest contractor faces numerous obstacles during the application of 100,000 square feet of high density fireproofing, but uses knowledge to answer challenges as well as critics.
Abrasive material forms a major component for surface preparation in coating applications. Since blasting method developed in 1890s, abrasive materials and its application methods also significantly improved to enhance blasting efficiency. In general, steel grit and shot ball are being used predominantly as metallic abrasives. Garnet and coal slag are used as non-metallic abrasives. Each abrasive is selected andapplied in accordance with the work location and substrate material of structures to be coated. In this study, we have evaluated a new artificial non-metallic abrasive (ferrochrome slag) which is a by-product from ferrochrome production process for stainless steel. This evaluation also included the checking of surface cleanliness performance and coating quality based on international test methods and field trials. For verifying the cleanliness quality, various tests were conducted as per international standards (ISO 8501-8503). Sea water immersion test (ISO 2812-2) and cyclic test (ISO 12944-9) were carried out to checkcoating performance after blasting. The field test results indicates that all inspection and quality criteria of surface preparation were met as per international standards. Furthermore, coating performance test results also showed this abrasive does not have any adverse effect on coating properties.
With modern advances in technology and materials, application equipment for two-part protective coatings has become easier to use. The benefits of using plural-component equipment far outweigh the risks. In today’s competitive market, plural-component sprayers provide the reliability and quality necessary to get work done and also provide the profit potential to help a business stay ahead of the competition.
This paper describes the polyaspartics coating technology and how it can be used to formulate relatively fast drying 2-coat corrosion resistant paints for use on steel substrates. The polyaspartics coating technology offers several advantages over the conventional two- and three-coat paints, including faster re-coat windows leading to an overall faster coating application process and lower costs.
Several coating systems and designs were chosen to protect a concrete chamber with side walls coated with a polyvinylidene fluoride (PVDF) material. When polyurea was identified as the coating to be used at this engineering pilot plant, which contains harsh caustic chemicals in conjunction with PVDF coated panel walls; an extensive research was conducted to determine which method will be utilized to create a seamless protective film between these two systems.
Polyurethane coating systems on parking structures are designed to prevent leaks, protect the concrete from deterioration, and prevent corrosion in the reinforcing steel
