ECE test detergent 77 (containing phosphate) and ECE test detergent 98 (phosphate-free)

Detergents currently not available

Our stock of these two test detergents is almost exhausted. Due to Corona, certain raw materials for the production of these two test detergents are currently not available, which is why a new production is not possible for an indefinite period of time.
We ask for your understanding that we are therefore unable to serve orders until further notice.

Lithiumhypochlorit

Lithium hypochlorite is no longer available

Despite intensive efforts, we have failed to re-source lithium hypochlorite on the world market. We regret this and ask for your understanding that we therefore had to remove lithium hypochlorite from our product portfolio.

Substitution of Sodium perborate by Sodium percarbonate in colour fastness testing of textiles

 

Standardized production of auxiliary products for colour fastness tests according to ISO 105 series

Due to high demand DEK had to synthesize new quantities of some of our colour fastness auxiliary materials.

Now we have good stocks of the Blue Wool References
1 – 8
and of the Grey Scale for Carpets.

All the newly synthesized products have been tested by accredited institutions and meet the requirements of ISO 105 and DIN EN ISO 105 series standards. All the materials for the testing of colour fastness of textiles from our stock are supplied with appropriate certification.


Conclusion:
For standardized testing of colour fastness according to ISO 105 and DIN EN ISO 105 series the use of auxiliary products supplied by DEK can be guaranteed that objective testing of coloured textiles will stand up to any comparison.
