SYNTHALAT A 078 HV

SYNTHALAT A 078 HV is a polyisocyanate-curing acrylic resin primarily used in two-pack coatings, which are air- and oven-drying in combination with aliphatic polyisocyanates. It offers good mechanical properties, resistance to chemical attack, and weathering. Here's a summary of its characteristics and properties:

Characteristics:

• Supplied as: 65% in shellsol A
• Hydroxyl value: 80-95
• Hydroxyl content: Approximately 2.6% (relative to non-volatile content)
• Viscosity (as supplied): 10,000-15,000 mPas
• Gardner colour value: < 2 (as supplied)
• Non-volatile content: 65 +/- 1%
• Flash point: Approximately 40°C
• Density: 1.01 g/ml

Pigmentation: Any neutral pigments or fillers are suitable for pigmentation with SYNTHALAT A 078 HV. However, basic pigments and pigments containing soluble metal compounds may affect curing and shorten the pot life of coating batches once mixed.

Mixing Ratio with Polyisocyanates: Based on an equivalent reaction of the reactive groups (NCO : OH = 1 : 1), the recommended mixing ratio with polyisocyanates is calculated using the provided formula.

Solubility/Dilutability: SYNTHALAT A 078 HV can be thinned with various solvents, including ethyl acetate, butyl acetate, xylene, etc. Only non-aqueous solvents and those containing no hydroxyl groups may be used.

Compatibility: SYNTHALAT A 078 HV exhibits compatibility with various other products, as listed in the compatibility table. It is compatible with Synthalat A 045, A 055, A 065, A 060, A 077, A 085, A 088 "MS," A 090, A 135, A 141 HS, A 150, A 1613, A 1633, A 1653, Synthoester HD-080, HD 170 HS, NC chips E 510, and others.
