Accoshield
Accoshield is a thermoplastic fluoropolyumer surface coating mainly applied to obtain non-stick and corrosive preventive properties.
Uses
Accoshield is used for many purposes e.g. reaction vessels, pipes, valves etc. in the chemical industry and in industries where corrosion protection of steel and / or stainless steel is required. With applicability of the coating at high temperatures (up to 250ºC) you will be able to use the coating where other coatings would not solve the problem. We have, e.g. good experiences with sulphuric acid in high consentrations at temperatures up to 240ºC.
As the coating has excellent non-stick properties it can also be used where easy cleaning and unproblematic material transportation are requested.
Technical information
The Accoshield surface is black smoot and half-mat. To obtain maximum adherence in order to finally give the item long durability the item - before the coating process - i cleaned and sandblasted to remove any inclusions. As this treatment involves a process temperature of 400ºC it is a precondition that the construction of the item can stand the temperature.
The surface coating itself is relatively soft and may be damaged by sharp tools etc.. It is therefore highly recommended that employees working with items coated with Accoshield are informed accordingly and use suitable tool such as rubber scrapers etc..
Test plates / samples
Free of charge we supply surface samples with different Accoat surface coatings. So you will be able to look and feel which surface properties are best suited for your purpose. Please contact our sale department to ask for relevant test plates.
Most substantiel properties:
1 = Moderate, 2 = Good, 3 = Very Good, 4 = Excellent
Property | Value |
| Layer thickness (µm) | 550 - 800 µm |
Colour | Black |
Range of temperature | 250ºC continuously |
Coefficient of friction | ABout 0,2 - 0,3 against steel |
Hardness (Shore D) | 60 - 65 |
Contact with foodstuffs | All constituent components are not in FDA's register, but the coating copes with the extraction tests requested. |
Material suited for coatings | Steel, stainless steel and aluminium |
Limitations | Use of sharp tools will damage the coating |
Safety | As the heating temperature exceeds 300ºC possible toxic acid gases may be given off: Therefore, do not weld etc. on metal parts close to the coating. To remove old coatings it is advisable to do it mechanically, e.g. by sandblastning. |
Additional information
As Accoat A/S has no control over the conditions under which its products may be used, Accoat A/S can only take responsibility that the coatings live up to standards appearing form our technical data sheets and sales material. The liability for damage can never exceed the price paid for the coating.
