SYNTHALAT A 055

SYNTHALAT A 055 is an acrylic resin designed for cross-linking with polyisocyanates. It is supplied as a 60% solution in xylene/butyl acetate (3:1).

Characteristics:

• Hydroxyl value: 55-65
• Hydroxyl content: Approximately 1.7% (relative to non-volatile content)
• Flow time in seconds (50% in xylene): 200-300
• Gardner colour value (50% in xylene): Less than 2
• Non-volatile content: 60 +/- 1%
• Flash point: 28°C
• Density: 1.00 g/ml

Use: SYNTHALAT A 055 is primarily used in combination with aliphatic polyisocyanates for non-yellowing coatings for metals and plastics. It can also be used as a pigment paste resin and is suitable for applications requiring high flexibility, adhesion, and weathering resistance.

Film Properties: When combined with aliphatic polyisocyanates like "Desmodur N," SYNTHALAT A 055 produces non-yellowing coatings with excellent weathering resistance, gloss retention, high flexibility, and good adhesion even on problematic substrates.

Compatibility: SYNTHALAT A 055 exhibits very high compatibility and can be used as a combining resin for various other products, including A 045, A 065, A 090, A 141 HS, and A 150/151, based on an equivalent reaction of the reactive groups (NCO:OH = 1:1).

Mixing Ratio with Polyisocyanate: The recommended mixing ratio with polyisocyanate is 100 parts by weight of SYNTHALAT A 055 to approximately 15 parts by weight of "Desmodur N 75%."

Solubility/Dilutability: SYNTHALAT A 055 is dilutable in various solvents like ethyl acetate, MIBK, butyl acetate, toluene, etc. It's important to use only anhydrous solvents without OH groups.

Shelf-life: If properly stored, SYNTHALAT A 055 has a shelf life of at least one year.
