How to store powder coating safely

how to store powder coating safely

Proper storage for powder coating prevents particle agglomeration and reaction advancement, and ensures satisfactory application,this is pivotal. During application powder coatings must be easily fluidizable, free-flowing, and capable of accepting and maintaining a good electrostatic charges. Factors affecting powder coatings storage The key factors affecting powder coatings storage can be identified as: Temperature Moisture / Humidity Contamination Direct sunlight The recommended optimum conditions for powder storage are: Temperature < 25°C Relative humidity 50 – 65% Away from direct sunlight EffectRead More …

Coatings Technology Knowledge:the characteristics of the powder coating

The powder coating is a new type of solvent-free 100% solid powder coating. It has two categories: the thermoplastic powder coating and thermosetting powder coating. Coating made of special resin, fillers, curing agents and other additives, to a certain proportion of mixed and then by hot extrusion and crushing process of sifting and other prepared from. At room temperature, storage stability, electrostatic spray or fluidized bed dipping, and then the baking heat of melting and solidification, so that the formationRead More …

Trends of Powder coating application in automotive market in USA

Powder coating surface treatment of ancillary products as durable goods applications, the main applications include automotive, residential, home, industrial equipment and gardening equipment and so on. Despite the current global automotive industry continued weakness in the case of GM and other car companies are going through bankruptcy, reorganization of assets and other major changes, but from the historical data show that in 2003 and 2008, automotive powder coating growth is very obvious. Automobile industry alone by 2013 there will beRead More …

Titanium Dioxide (TiO2) the most important and widely used in the coatings industry

Titanium Dioxide (TiO2) is the most important and widely used white pigment in the powder paint and coatings industry. Its combination of optical and physical properties make this pigment suitable to bring needed performances for a wide range of different coating applications. Incorporated correctly , this pigment helps to tune up the formulation to obtain many properties such as superior gloss, brightness, tint strengh, ease of dispersion, durability, hiding power and batch to batch uniformity. TiO2 is used to opacify paintRead More …

How to control the quality of matting agents dispersion in powder coating or paint

When we use fillers as matting agents in powder paint or coatings it is advisable to measure Grindometer or Hegmann value in order to receive information about the dispersing degree. Second, we can control the gloss degree at an angle of 60°. For the other above mentioned product groups the main parameter should be the control of gloss behavior. However, in order to get an extensive understanding about the matt degree of the paint it is necessary to take measurements atRead More …

VOCs or HAPs per weight of solids

The older regulations were concerned with VOCs,while the newer ones have been written with the focus on HAPs.The calculation methods are very similar. The description below is written in terms of VOCs,but the formulas apply if everything applying to VOC solvents below is taken simply to apply to HAP solvents. Another way to handle the presence of non-VOCs is to calculate the ratio of the weight of the VOC solvents to the weight of the solids, rather than to theRead More …

Thermosetting powder coating and thermoplastic powder coating

Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin”.They are applied as a dry material and they contain veryRead More …

What is Zinc Phosphate Coatings

Zinc phosphate coating is preffered in case of requirement of higher corrosion resistance than iron phosphate. It can be used as base for paintings (especially for thermosetting powder coating), before cold drawing / cold forming of steel and prior application of protective oil / lubrication. This is often the method chosen when long life under corrosive conditions is required. Coating is also very good with zinc phosphate because the crystals form a porous surface which can soak up and mechanicallyRead More …
