| Compatibility of soluryl R-20B
| Soluryl R-20B emulsion is compatible with a wide range of resins including styrenated shellacs,acrylics and rosin maleics. Dilution with glycols,glycol ethers and alcohols is excellent.| | Emulsion : Soluryl R-20B | | Emulsion | 3:1 | 1:1 | 1:3 | | Soluryl-351/352 | C | C | C | | Soluryl R-90/90G | C | C | C | | Soluryl R-9061 | C | C | C | | Soluryl R-20B | C | C | C | | Soluryl E-80F | C | C | C | | Soluryl E-8040 | C | C | C | | Soluryl RX-20/30 | C | C | C | | Soluryl SX-1420 | C | C | C |
|
| Dilution Characteristics
| | Soluryl R-20B can be diluted with water/alcohol blends.It is advisable to pre-mix solvents before adding to the polymer to avoid any possible solvent shock. |
| Pigmentation
| | Soluryl R-20B emulsion provides good wetting and dispersion for both organic and inorganic pigment.As with all water-base carboxylated acrylic polymers, care must be taken with barium and calcium based organic red pigments as certain types can cause tickening. The best results are obtained by dispersing the pigments into Soluryl-70 and letting down with Solury R-20B. |
| Formulation Tip
| | SolurylR-20B emulsion has very low foaming tendencies and excellent flow properties.Excellent printability and tranfer by flexography and Gravure is accomplished with Soluryl R-20B formulations with proper defoamer selection and only small amount of defoamer are needed when formulating. | | In case of resolubility problem, it is advisable to add 0.1-0.5% of amines or glycols with high boiling point, or to mix with 10-15% of high Tg emulsions such as Solury RX-30, R-40orR-90 |
| Safety Information
| | Soluryl R-20B is not formulated to contain any hazardous or regulated materials such as lead, cadmium, mercury and chromium compounds. And raw materials for Soluryl R-20B and our manufacturing process do not includ any hazardous or regulated materials. |
