SYNTHALAT A 078

SYNTHALATA 078 is a polyisocyanate-curing acrylic resin supplied in a 60% concentration in Shellsol A. Here are its key characteristics, properties, and recommended use:

Characteristics:
- It is a polyisocyanate-curing acrylic resin.

Use:
- Typically used in 2-pack coatings that are air- and oven-drying in combination with aliphatic polyisocyanates.
- Commonly employed for industrial coatings offering good mechanical properties, resistance to chemical attack, and weathering.

Properties:
- Hydroxyl value: 80-95 (measured according to in-house method AV-F-H003)
- Hydroxyl content: Approximately 2.6% (relative to non-volatile content)
- Viscosity: 2000-2500 mPas (measured according to in-house method AV-F-V005)
- Gardner colour value: < 2 (as supplied) (measured according to in-house method AV-F-F007)
- Non-volatile content: 60 +/- 1% (as supplied) (measured according to in-house method AV-F-F003)
- Flash point: Approximately 40°C (as supplied) (measured according to in-house method AV-F-F006)
- Density: Approximately 1.00 g/ml (as supplied) (measured according to in-house method AV-F-D001)

Pigmentation:
- Suitable for pigmentation with any neutral pigments or fillers. However, basic pigments and pigments containing soluble metal compounds may catalyze curing and shorten the pot life of mixed coating batches.

Mixing Ratio with Poly-isocyanates:
- The quantity of polyisocyanate to be added relative to 100 parts by weight of solid SYNTHALATA 078 can be calculated based on an equivalent reaction of the reactive groups (NCO : OH = 1 : 1) using the provided formula.

Solubility/Dilutability:
- It shows good solubility and dilutability in various non-aqueous solvents with no hydroxyl groups. The table provided indicates the clarity of the solution at different concentrations.

Compatibility:
- The compatibility of SYNTHALATA 078 with various other Synthapol products and external materials is provided, indicating whether they are compatible or incompatible at different concentrations.
