برگه اطلاعات فنی کالا TDS
- Efka® RM 1400
- (old: Rilanit® R4 )
- Use
- RILANIT® R 4 is a liquid additive which, when stirred into solvent-type air-drying paint systems, will produce a stable thixotropic viscosity increase. This offers a number of advantages such as:
- - sag control
- -bodying
- - flow control
- - reduction of pigment settling,flooding and floating.
- Composition : RILANIT® R 4 is an anionic vegetable oil derivative.
- Specification
- Appearance viscous brownish liquid (8000)
- pH value (10%) 7.5 - 8.5 (8228, UNE-EN 1262)
- Active substance 78 - 82% (8625)
- Brookfield viscosity 1.000 - 3.000 mPa•s (RVT, sp-3, 20 rpm, 20 ºC,8032, EN 1791)
- Application
- RILANIT® R 4 is used exclusively in pigment coatings based on binders air-drying by oxidation,such as alkyd resins and drying oils. RILANIT® R 4 gives good performance in systems not having an extremely low viscosity and with a pigment volume concentration of above 25 - 30%. It cannot be used in paints containing metallic pigments. Although the presence of active pigments, calcium or zinc soaps, to activate the performance of RILANIT® R 4, is not required, the addition of such products may increase the effect of the additive.
- Dosage
- As already mentioned above RILANIT® R 4 may be added during any stage of production of pigmented coatings; however, the following methods are suggested:
- Post-additive to the finished paint:
- If a subsequent correction of the flow properties is desired,RILANIT® R 4 may be incorporated into thepaint by stirring. A stable viscosity increase will result after a few hours.
- Grinding aid:
- RILANIT® R 4 may be added to the mill base if, besides the advantages resulting
- from thixotropy, better pigment dispersion is desired. This method is also recommended if,because of strong pigment settling, good suspension properties as well as «bodying» are required.
- If this method is used, pigment floating and flooding may also be reduced. When grinding RILANIT® R 4 together with the pigments, full thixotropy will develop within approximately 12 hours.
- Given the same pigmentation, the performance of RILANIT® R 4 is about proportional to the amount added. The quantity required is usually between 0.25 - 1.0%, calculated on finished paint.
- Besides paint type and composition, the level of pigmentation is the most decisive factor in selecting the correct dosage of RILANIT® R 4. With rising pigment-volume concentrations, equal amounts of RILANIT® R 4 will cause an increase in thickening.
- Considering the large number of possible varations of paint formulations, RILANIT R 4 should first be tested under laboratory conditions.
- If RILANIT® R 4 is intended for use in coatings with high performance requirements regarding drying, yellowing and anti-corrosive properties, its suitability should be confirmed by laboratory evaluations, particularly if it is necessary to use a large amount of this additive.
