Liocrylam 923 is an aqueous, self-crosslinking pure acrylic emulsion with free hydroxyl groups, characterized by fine-particle size and being solvent- and plasticiser-free. Here's a summary:
Characteristics:
- Aqueous, self-crosslinking pure acrylic emulsion with free hydroxyl groups.
- Fine-particle size.
- Solvent- and plasticizer-free.
Supplied as:
Properties:
- Non-volatile content: 40 +/- 1% (as supplied).
- Viscosity in mPas: 20 - 500 (as supplied).
- pH-value: 6.5 - 8.0 (as supplied).
- Minimum film-forming temperature in °C: Approximately 46.
- Density in g/cm³: Approximately 1.04.
- Theoretical hydroxyl value: 60.
- Emulsifier system: Anionic.
Properties and fields of use:
- Particularly suitable for formulating aqueous 1-pack and 2-pack wood and furniture varnishes.
- Can be combined with Liopur polyurethane dispersions for this purpose.
- Exhibits high chemical resistance and yellowing resistance.
- Offers excellent transparency in the wet film and very good grain enhancement due to its fine particle size.
Storage:
- The emulsion should be stored in tightly closed, corrosion-resistant containers, protected from frost and direct sunlight, at temperatures ranging from +5 to +25°C.
- It is preserved for storage and does not contain formaldehyde or formaldehyde-releasing products. Additionally, it contains no alkyl phenol ethoxylates (APEO’s).
