LOW FORMALDEHYDE NON-IRON FINISHING RESIN RG-220AMain Ingredient: Modified DMDHEUPhysical and Chemical Indicators: Appearance: Clear and light yellow solutionIonicity: NonionicDensity: 1.14-1.16g/cm3 (at 20ºC)PH Value:4.0-6.0 Effective content: 50-53%Solid content:40-45%Reactivity: Good Performance characteristics and Application:Cross-linking agent of textile wash and wear non-iron finishing, mainly applied in the resin finishing of cotton, viscose, and its blended woven fabric or knitted fabric. Or can applied in embossing, lightning, calendering and bubbling. Also can be applied in shrink water finishing on full cotton and blended. The fabrics treated by this product have a good non-iron property, very high hydrolytic ability, very good chlorine resistance, durable for water cleaning and dry washing, with good hand feeling. The free formaldehyde is very low. The textile treated by this product complies to the requirement of "K-Tex standard 100"Tested according to Law112, free formaldehyde content is less than 150ppm. Application Method: Firstly adjust the PH value of the fabric to PH value<6.5.
The following recipe suggested add 2g/l penetrating agent, and adjust the PH value to < 4.0-4.5 by citric acid / acetic acid.
Padding/Dipping in room temperature, dosage as blow:
| Fabric | Cotton | Viscose | Polyester/Cotton | Polyester/Viscose |
| RG-220A | 40-90 | 80-120 | 30-70 | 40-80 |

expression | 70-80 | 80-90 | 70-80 | 70-80 |
Take Magnesium chloride as a catalyst is suitable for various fabrics.
Dosage of catalyst: 15% of RG-220A, but not less than 8g/L ( number base on MgCl2·6H2O crystal). Fabric after prebaked should baking under high-temperature 150ºC, 2-3 minutes or 170-175ºC, 60-30 seconds.

It has good permeability. Fabric treated by this product can don't need after-wash process,
But after the wash process can help to remove the residual reactant of the surface, to make the fabric hand feeling better. A necessary Preliminary test was needed on any occasion before production.
Package and Storage: Package: 50kg or 130kg plastic drum.Avoid exposure to the sunlight frozen, in a cool, ventilated place. Storage at room temperature, the guarantee period is one year.If stored at a higher temperature, the appearance would the trend of yellow, but will not affect the product effective and usage.
