SYNTHALAT TH 30 HS

SYNTHALAT TH 30 HS is a short-oil alkyd resin modified with phenolic resin primarily used for air-drying and oven-drying primer coatings in industrial applications such as machinery and steel constructions. Here's a breakdown of its characteristics, properties, and recommended usage:

Characteristics:

• Type: Short-oil alkyd resin modified with phenolic resin
• Composition:
  • Approximately 27% phthalic acid anhydride content
  • Approximately 31% linseed oil
  • Approximately 14% modifying resins
• Supplied Forms:
  • A) 80% in xylene
  • B) 75% in Shellsol D 25 / Solvenon PM

Use:

• Ideal for air-drying and oven-drying primer coatings in industrial applications like machinery and steel constructions.
• Relatively low viscosity allows the preparation of primers and topcoat varnishes with significantly higher non-volatile content and good drying properties, even in thicker coating layers.

Properties:

• Viscosity (mPas):
  • A: 12000 – 22000
  • B: 2000 - 8000
• Acid Value: < 20 (based on non-volatile content)
• Iodine Color Value: < 20 (diluted to 50% with xylene)
• Non-volatile Content (w %):
  • A: 80 +/- 1
  • B: 75 +/- 1
• Flash Point (°C):
  • A: 37
  • B: 29
• Density (g/ml): Approximately 1.04 (A), Approximately 1.03 (B)

Solubility:

• Compatible with various solvents including oil of turpentine, toluene, xylene, solvent naphtha, ethyl acetate, butyl acetate, methyl ethyl ketone, methyl isobutyl ketone, and more.

Compatibility:

• Compatible with linseed oil, linseed oil-stand oil, medium-oil drying alkyds, alkyl/terpene phenolic resins, phenolic-modified colophony resins, unplasticized urea resins, unplasticized melamine resins, and ester-soluble nitrocellulose.

Overall, SYNTHALAT TH30HS offers excellent properties for producing high-quality primer coatings with good drying properties and compatibility with various substrates and additives commonly used in industrial coating applications.
