WorléeKyd S 351(50% In Isoparaffin HC 170-200) is a medium oil length alkyd resin modified with soya oil, primarily used for air-drying applications. Here's a breakdown of its specifications and applications:

Description:

• W´Kyd S 351 is designed for the manufacture of fillers with structural viscosity for brushing, primer surfacers, and semi-gloss and flat wall paints.

Technical Data:

• Oil content: Approximately 51%
• Oil type: Soya oil
• Content of phthalic anhydride: Approximately 23%
• Non-volatile content, 1h/125 °C, DIN EN ISO 3251: 50% ± 1
• Colour (40% in isoparaffin. HC 170 - 200, DIN ISO 4630): Maximum 10
• Acid value, on solids, DIN EN ISO 3682: Maximum 15
• Flow time, 20 °C, 40% in isoparaffin. HC 170 - 200, DIN 6 mm cup, DIN 53211-6: 70 - 100 sec.
• Delivery form: 50% in isoparaffin. HC 170 - 200

Compatibility:

• W´Kyd S 351 is completely compatible with most air-drying medium and long oil alkyd resins, maleic resins, phenolic modified rosins, raw oils, and chlorinated rubber. It is partially compatible with low viscous stand oils.

Solubility:

• Well soluble in all solvents except for low alcohols.

Application and Properties:

• Recommended for primers with excellent flow properties and brushability. Good film flow is achieved even at high PVC (pigment volume concentration).
• Despite quick drying, the film remains open long enough for painting large surfaces, with sanding possible after approximately 20 hours of drying time.
• Addition of thixotropic agents or combination with thixotropic alkyd resins enables the production of flat wall paints with excellent brushability and no tendency to sag or drip from the brush.
• Well suited for flat and semi-gloss interior paints with good yellowing resistance and brushability, especially for primed and porous substrates.
• Addition of small amounts of matting agent can produce flat and semi-gloss paints.
• Ready-made paints with W´Kyd S 351 have no tendency to sink on porous substrates.

Driers:

• Recommended driers:
  • 5.00 - 6.50% Nuodex Combi APB-solution (Elementis) on solid alkyd resin.
  • Alternatively, 0.10 - 0.20 % Co and 0.05 - 0.07% Zr (metal content on solid alkyd resin).

WorléeKyd S 351 offers versatility and performance in various coating applications, providing properties such as good flow, brushability, and sag resistance, particularly in flat wall paints and primers.

SYNTHALAT W 48 is a water-thinnable special modified alkyd resin primarily used for top coat formulations with good color retention and excellent water resistance. Here are its characteristics, properties, and recommended usage:

Characteristics:

• Type: Water-thinnable special modified alkyd resin
• Composition:
  • Oil Type: Drying fatty acids
  • Oil content: Approximately 42%
• Supplied as: Approximately 35% in BG/ammonia/water (8:0.5:56.5)

Use:

• Ideal for water-thinnable top coat formulations requiring good color retention and very good water resistance.

Properties:

• Viscosity: 2,000-5,000 mPas (as supplied)
• Appearance: Opaque
• pH-value: 7.5-9.0 (10% diluted with water)
• Non-volatile component: 35 +/- 1%
• Flash point: Approximately 62°C
• Density: Approximately 1.01 g/ml

Film Properties and Processing:

• Used as a sole binder for water-thinnable single-coat and top coat formulations.
• Coatings exhibit early water resistance, with white top coats maintaining high whiteness retention.
• Can be dried by forced-air drying (e.g., 15 min./85°C) or at room temperature for 24 hours, resulting in good resistance to rain, mist, and high atmospheric humidity.
• Rapid drying makes coatings suitable for spray application, brush painting, and dip coatings.
• Suitable for finishing agricultural equipment, commercial vehicles, construction machinery, and general industrial use.
• Essential to adjust the pH of the coating by making up the neutralizing agent that has volatilized during dispersion, recommending a pH adjustment to 9.0 to 9.5 with ammonia.
• Recommended drier combinations: 0.05%-0.15% Co, 0.1% Ca, 0.1-0.5% Zr (relative to metal content on solid resin).
