WorléeKyd S 351

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.
