Technical Questions

How do I get detailed information about a product?

Answer: The best way to contact us directly at: info@trueb-chemie.com

and give us the information for which application you want the product.

How do I get a technical data sheet?

Answer: For the preservation of the technical and safety data sheets, please contact us directly at: info@trueb-chemie.com or via phone +41/52 742 83 83

How do I find the food approvals and food conformities?

Answer: The food approvals are specified on the technical data sheets. On request we can provide you a specific food conformity.

What are the storage conditions for aqueous dispersions/emulsions?

Answer: use immediately after packaging dawn. Protect from frost and store at temperatures between + 5 ° C - + 25 ° C. 
Stir well after storage before use. No longer return once used goods in the containers-Risk of contamination!

Are detailed migration data are available for the products?

Answer: We as a manufacturer of dispersions/emulsions hold no migration data ready, because the specifications, depending on the field or type of food, are too different - Please do as a customer always the migration analyzes, we will support the responsible institute.

What is the sensitivity to frost

Answer: Many of our products are sensitive to frost, but some not. It is best to inquire in advance when ordering and remember, if you organize the cargo itself, that you commission a thermal transport for pickup. Is a dispersion or emulsion once frozen, contact us, we will give you the necessary information on the potential usefulness of the product.

Are the products among themselves freely combined?

Answer: they are not. Ask the lab if and how products can be mixed our technicians, or test yourself product combinations advance in the laboratory on a small scale. Each mixing operation should take place with stirring!

The intolerance often is due to the ionicity of the dispersions or of additives, which are not compatible with the other ingredients dispersions.

 

How are the products applied to the substrate, what options are there?

Answer: The products can be applied with the most common application methods such as roller coating, spray coating, curtain coating, Stamps contract variants, dipping, etc. by hand, the products are applied by means of pulling rods or blade on paper, foils etc..

Which driers/conditions are necessary to be able to process these products?

Answer: For water based products you always need a higher drying temperature and a longer drying time as with solvent-based systems. Depending on the emulsion/dispersion, the drying temperatures should be at least between 80 ° C and 150 ° C. Most products come with 80 - of 120 ° C. The drying time is ideally between 10-25 seconds. For most of our products is 15 seconds a good average.

The drying equipment used should achieve these temperatures and drying times, no matter what drying variants circulating air, exhaust, dry road, etc. use. Proper drying is essential for the function of the product, since this forms a seamless film with the desired properties.

How are the products preserved?

Answer: dispersions and emulsions are preserved at Trüb Emulsions Chemie AG with isothiazolinones and mixtures of these representatives as well as with 40% formaldehyde solution. The isothiazolinones are mostly methylisothiazolinone, benzisothiazolinone and Chlorisothiazolinon. The formaldehyde solution is not combined as a preservative for use. To bear in mind is: Isothiazolinone remain even after drying in the films and finished products, formaldehyde evaporates during drying completely from the coating. Therefore, formaldehyde, despite hazard classification, often used for the preservation of dispersions and emulsions for food packaging.

Are the products registered under REACH? Meets Trüb Emulsions Chemie AG Regulation 1907/2006/EC, if so, how?

Answer: The Trüb Emulsions Chemie AG complies with the REACH legislation in accordance with Regulation 1907/2006/EC. We have to regulate a subsidiary, the ECP-AG (European Chemical Products-AG) was founded in Liechtenstein in order to carry out from there all the necessary registrations and Pre-registrations. Our dispersions and emulsions are not polymers within the meaning of Regulation 1907/2006/EC and therefore Chemie AG were of the Trüb Emulsions preregistered all ingredients in their products. We always check our supply by already concluded commodity registration from our suppliers and can provide you from a current REACH confirmation for the product delivered to you.

What is the shelf life of products designed?

Answer: The shelf life is 6 months from the date of delivery. For longer storage periods, the products can be most definitely still used.
We are happy if you can contact us in occurred case to support you.

What is the solvent compatibility of the products?

Answer: Compared with the solvent such as ethyl acetate, methyl ethyl ketone, acetone, etc. classically used the dispersions and emulsions are incompatible, that means it comes to gel formation, flocculation, aggregation etc.

Few solvents can, with stirring, to a certain percentage (as a drying aid, coalescent etc.) are incorporated classical representatives are here isopropanol, ethanol, methanol, propanol, butyl glycol other glycols, glycol ethers. The compatibility of these solvent additions and the tolerated amount, you elicit the best in laboratory studies, from experiences are additional amounts of 5-40%, depending on the underlying dispersion/emulsion and used solvents, possible.

How, and with what the products are further diluted?

Answer: demineralized, deionized or distilled water.

Never use tap water, hard water, otherwise the products will be destroyed!

If the water-based products are actually free of solvent?

Answer: Yes. It may be that used for dispersing resins contain a certain Glycol or Glycoletheranteil in 0, xxx% range, but in general our products are completely free of solvents

How are machine cleaned most effectively of the products?

Answer: are most effective used equipment, machinery, immediately after use with plenty of demineralized (if possible warm demineralized water) or deionized or distilled water wash systems. You can also take warm hard-water, but this leads to flocculation, what the cleaning effort or the necessary amount of water then rather increased.

If you have to clean dried-points it will be more difficult, often they have to be replaced with methyl ethyl ketone or isopropanol wipe and rinsed with demineralized water.

What is the biological degradability of the dispersions and emulsions?

Answer: Biologically, the polymer dispersions and Emuslionen poorly degradable.

The aqueous dispersion/emulsion itself is quite rapidly degradable, the decay into their constituent parts, but the remaining plastic is difficult to break down.

Maintains the Trüb Emulsions Chemie AG a quality assurance system?

Answer: Yes. We maintain a certification in accordance with DIN EN ISO 9001:2008 for our regulatory processes and quality guarantee, as well as DIN EN ISO 14001:2005 certification for the safe handling of our environment through established processes for recycling/disposal of our used and waste materials and good manufacturing pure water-based products.
