Features & Benefits

Product Highlights
  • The Deuteron® OG 882x product family is a series of fine PMU (Polymethyl urea) particle dispersions in TMP(EO)3 TA (Ethoxylated Trimethylolpropane triacrylate). In the product family three different grades with different particle size distributions are available.
  • The variety of different particle size distributions enable formulators to find the right particle size distribution for many different applications down to extremely thin films.
  • Depending on the addition level Deuteron® OG 882x can be used as scratch resistance additive for high gloss applications or as matting agent for high quality applications. The use of our PMU chemistry leads to high hardness, low COF (coefficient of friction) products that are able to maintain high gloss levels.

Application and Dosage Information

The Deuteron® OG 882x family is generally suitable in all UV curable applications where DPGDA is acceptable.

Preferred applications are:

  • Overprint varnishes
  • Floor coatings (PVC, laminate floorings and wood floors)
  • Wood coatings

The use of Deuteron® OG 882x especially improves the following properties:

  • Reduced COF (coefficient of friction)
  • Surface protection
  • Scratch and polishing resistance
  • Low impact on the gloss level at low dosages
  • Matting at high dosages in thin layer applications
  • Pleasantly surface haptics
  • Excellent recoatability
  • Temperature resistant up to over 200 °C, short- time up to over 300 °C
  • Mimic wax effects without negative influence of waxes
  • Biodegradable polymer

Dosage

  • Typical addition range (high gloss): 1.0 % - 5.0 %
  • Typical addition range (as matting agent): 8 % - 25.0 %
  • The required dosage level highly depends on the system (e.g. binder type, additives, solvent content, etc.) and application parameters such as layer thickness and film shrinkage. Thus, it is highly recommended to determine the needed addition level by a practical ladder study.

Processing

  • Deuteron® OG additives are easy to disperse and can be incorporated using a common high-speed stirrer. It is recommended to add Deuteron® OG additives while stirring to avoid eventual agglomeration caused by concentration differences. Because of their easy to use supply form the additives can be used as post-addable materials. Additional grinding should be avoided.
