Surface Cleanliness

A clean and well prepared surface is crucial for a successful coating performance.

The pre-treatment process of an industrial coating job often consumes more time and budget than the actual paint application itself.

A clean and well prepared surface is crucial for a successful coating performance.

The pre-treatment process of an industrial coating job often consumes more time and budget than the actual paint application itself. 

Surface preparation
There are various methods and systems to prepare a surface prior to the coating application. Depending on the project and job specifications one could choose for hand cleaning like brushing, grinding or using needle hammers. Often grit blasting is utilised or shot blasting in automatic line for example. If no anchor pattern is required or already in place (ultra) high pressure water jetting, chemical cleaning or a simple wash down might be the solution.

  • Roughness and Blasting Profile

    Surface profile
    Surface profile, also addressed as surface roughness or anchor pattern is another parameter that plays an important role in the surface prep process. Besides a clean surface a certain roughness may be required to assure proper adhesion of the paint or coating to the surface.

  • Soluble salts / Chlorides

    Cleanliness
    Cleanliness is providing information about the level of contaminants which are left on the surface. This contamination could be (blast) dust, soluble salts like chlorides, old paint residues, oil and fat, (flash) rust, mil scale, condensation and moisture, amines, etc.. 

    Surface contamination can be caused in many different ways like insufficient cleaning, residue left after (acid) rain showers, sea salt left on the surface in maritime environments, soluble salts introduced by contaminated recycled blasting media and many others.

  • Normy a Publikace
  • The surface energy is one decisive criterion for the adhesion of printing ink, glue, varnish, etc. on many plastic and metal surfaces. It is given in mN/m (millinewton per meter, currently valid unit) or in dyn/cm (dyne per centimeter, old unit, same numerical value).

  • The TQC Bresle Kit - Chloride Test Kit complies with the ISO 8502-6 and ISO 8502-9 standards that describe the Bresle Method to assess the level of soluble salts using a Bresle patch or Bresle sampler, distilled water and a conductivity gauge. The conductivity is mainly directly proportional to the concentration of dissolved chloride ions in the solution. 

  • Description: ISO 8501-1:2007 is a hardback A5-format book in four languages (English, French, German and Swedish), which specifies a series of rust grades and preparation grades of steel surfaces. The various grades are defined by written descriptions together with photographs that are representative examples within the tolerance for each grade as...

  • The TQC Spring Loaded Roller is used to perform objective dust tests according ISO 8502-3, and eliminates the human error by pressing with a constant force on the dust test tape. The ISO 8502-3 quantifies the quantity and size of dust particles on surfaces prepared for painting using a standarized tape for dust test.

  • The TQC Dust Test Kit according to ISO 8502-3 allows assessment of the quantity and size of dust particles on surfaces prepared for painting. Dust on blast cleaned surfaces can reduce coating adhesion, leading to premature coating failure and sub-standard coating finish. The dust test kit can be used in accordance with the recommendations of BS EN ISO...

  • The TQC DewCheck 4 - Dewpoint Meter (DPM)/ Dewmeter is an extremely versatile dewpoint meter to measure and record all climate parameters required to treat surfaces. This easy to use and robust dewmeter conforms to ISO 8502-4 & ASTM D3276-07 and measures the relative humidity (%RH), ambient temperature (Ta) and surface temperature (Ts) and calculates the...

  • The Fitz's Atlas 2 of coating defects is a reference manual with over 300 colour images, providing a clear and concise description of all problems that could occur, as well as their possible causes.The book is divided into the following sections: 

  • The TQC surface profile roughness gauge is a simple instrument for ultrafast measuring of the point peak-to-valley height of a surface. The shape of the base makes this instrument ideal to measure the height of welds.

  • With the new Surface Profile probe you can use the body of the PosiTector 6000 as a SPG Surface Profile Gauge. The SPG Surface Profile probe measures and records peak to valley surface profile heights. 

  • Digital spring micrometer measures and records peak to valley surface profile height using replica tape.All PosiTector 6000 probes can be used with the PosiTector SmartLink

  • The TQC Surface Profile & Coating Thickness gauge is a combination gauge. that can be equipped with two different tips, one for surface roughness and another for coating thickness. Supplied with a sharp tungsten carbide replaceable tip for surface profile measurement, a hardened round tip for coating thickness measurement, a glass plate for zero...

  • Comparators for determining surface roughness by touch and sight. Conforms to ASTM D4417. The KTA standard has 5 different grades of roughness and is available in three different versions. Available in Imperial units only.
