SYNTHOESTER C 455

SYNTHOESTER C455, formerly known as SE TC 1055, is a cyclo-aliphatic, hydroxyfunctional polyester resin supplied in a 65% concentration in Solvesso 150 ND/Butylglycole (3:1 ratio). Here are its key characteristics, properties, and recommended use:

Characteristics:
It is a cyclo-aliphatic, hydroxyfunctional polyester resin.

Use:
- Typically used in combination with melamine resin for producing high-durable stoving enamels with excellent weathering and color stability.
- Stoving conditions typically involve temperatures of 130°C and higher, particularly suitable for applications in the can and coil coating sector.

Properties:
- Exhibits excellent flow, scratch resistance, tough elasticity, chemical- and weather resistance, chalk resistance, adhesion, and pigment wetting.

Key Property Values:
- Non-volatile content: 65 +/- 1% (measured by heating 1g of resin at 125°C for 1 hour in 2 ml ethyl acetate)
- Viscosity: 2400 - 3200 mPas (measured by Haake at 23°C)
- Hydroxyl value: 20 – 40 (relative to non-volatile content)
- Hydroxyl content: 0.9% (relative to non-volatile content)
- Colour value: < 2 (as supplied)
- Density: Approximately 1.02 g/ml (as supplied)
- Flash point: Approximately 63°C (as supplied)

These properties make SYNTHOESTER C455 suitable for applications requiring high-performance coatings with durability and weather resistance.
