AntiCorrosive Pigments

The future trend in anticorrosive pigments is to obtain chromate free and heavy metal free pigments and to go in the direction of sub-micron and nanotechnology anti corrosive pigments and smart coatings with corrosion-sensing. This type of smart coatings do contain microcapsules containing pH indicator or corrosion inhibitor or/and self healing agents. The shell of the microcapsule breaks down under basic pH conditions. The pH indicator changes color and is released from the microcapsule together with corrosion inhibitor and /Read More …

Antimicrobial Coatings

Antimicrobial coatings are being used on a generous scale, in many ranges of application, varying from anti-fouling paints, coatings used in hospitals and on medical equipment, to algaecidal and fungicidal coatings in and around the house. Until now, coatings with added toxins are being used for these purposes. A growing problem in our world is that on the one hand, for reasons of health and environment, more and more biocides are being prohibited, while on the other hand bacteria areRead More …

Good choice of Antibacterial epoxy powder coating with excellent anti-corrosion

In the oil field oil and water pipelines, there are a lot of bacteria, especially sulfate-reducing bacteria, iron bacteria, the existence of saprophytic bacteria and multiply incessantly and pipe scale, and are subject to severe clogging and corrosion, a direct impact on oil production, oil and water injection. Oil field water pipelines, generally using the anti-corrosion of the steel pipe lined with cement mortar, the use of strong alkali in the cement mortar to inhibit bacterial attachment and reproduction toRead More …

Nanotechnology is rapidly gaining recognition to significantly benefit for the coatings industry

Nanotechnology is rapidly gaining recognition as having the potential to provide significant benefits for the coatings industry. The most publicized benefits include scratch resistance, UV protection and weathering protection. In addition to improved coating performance, nanotechnology also provides benefits, such as reduced energy and reduced material consumption. Nanoparticles including metal oxides, clays and resins dominate the market for nanotechnology-based coatings. Newer carbon based nanotubes are now being developed for use in transparent conductive coatings and low weight, high strength coatings.Read More …

Some ingredients may influence the antibacterial performance

Presence of some ingredients in the formulation may influence the antibacterial performance of silver additives.Some antioxidants, imdidazole derivatives and fillers like calcium carbonate may influence the antibacterial performance of powder.One more suspect is barium sulphate which might spoil the activity of silver because sulphur has a feature which reacts with silver easily. As silver ions have a tendency to react with atmosphere sulphur and exchange the ions it may have some impact. However our present experiments show good performance withRead More …

Coating thickness and silver addivtive dosage effect the antimicrobial performance

Dry film thickness of coatings Silver additive is necessary to expose appropriately on the top surface of the coated components for better antibacterial performance. Migration of antibacterial agent to the surface of the coatings is most important to achieve the best antibacterial protection. However this migration depends on number of factors such as thickness of the coatings, binder content, recipe of formulation, dosage level of antibacterial agent, degree of cross linking, cross reaction of antibacterial agent with other ingredients(i.e. disturbanceRead More …

Mechanism of silver technology used in antibacterial powder coating

For the present study inorganic antibacterial agent silver type is used. Five different types of silver additives are tried. The silver additives used is a composite of active silver ions, sodium ions and other ions (e.g. Zn). In some additives silver is embedded into a base material such as zeolite & glass matrix etc. Silver ion is a natural inorganic antibacterial agent which is effective in fighting against bacteria, fungi& moulds. Silver ion is generally preferred for its a. BacterialRead More …

Bright Application scopes for antibacterial powder coating

Why Antibacterial powder coating Antibacterial and anti mould properties are required when powder coating are used to such applications that coated objects are contacted with number of people and in the fields of foods, medical care and sanitation etc. Antibacterial powder coating helps to fight against disease and infection; the system also stops the growth of bacteria and fungi. The advantages of this technology are It doesn’t require any additional capital investment and the conventional extrusion and dry blending operationRead More …

How to select Antibacterial agent for antibacterial coatings

Selection of Antibacterial agent Number of antibacterial agents and fungicides are available for antibacterial powder coating. However it can be broadly classified into three types, each type of additive has its own advantages and some disadvantages. Natural antibacterial agent: They are difficult to handle as they posses relatively low boiling point. Organic antibacterial agent: Though these additives are compatible with the resins they have a problem of low stability so that their efficiency is lost during the melting stage. InorganicRead More …

How silver ions works in antimicrobial powder coating

Antimicrobial powder coating is widely used in many industries nowadays,such as Building Products,Food Service,Healthcare,Home Products and Packaging.This kind powders contain a silver ions,which act as antagonist over many bacterium. With the presence of moisture, silver ions are gradually released to function as an anti-microbial material. Silver ions charged with plus are drawn toward the microbe’s cell wall charged with minus to disturb the electrical balance. The cell wall of the microbe thus bursts and is extinguished. As silver ions enterRead More …
