LIOPTAL B 49

Lioptal B49 is a fast-drying medium-oil alkyd resin primarily used in various coatings applications. Here's a breakdown of its technical details:

Characteristics:

• • Fast-drying medium-oil alkyd resin.
  • Composition: Contains approximately 49% of vegetable fatty acids (with a low content of linolenic fatty acid) and an OH content of about 1.9%.

Supplied as: 55% in white spirit ("K 30") / xylene (6:1).

Use:

• • Suitable for machine and automotive coatings, radiator paints, industrial coatings and primers. Can be used with melamine resins for stoving at 80°C and for effect coatings.

Properties:

• • Non-volatile content (nvc): 55 +/- 1% (as supplied).
  • Flow time (from DIN cup, 4 mm, 20 °C): 40 - 55 sec (diluted to 40% with white spirit "K 30").
  • Acid value: Maximum 12 (relative to nvc).
  • Color value (iodine): Maximum 5 (diluted to 40% with white spirit "K 30").

Compatibility: Compatible with various resins and solvents, including linseed oil, short-oil drying alkyds, medium-oil drying alkyds, epoxy esters, maleic resins, and phenolic-modified colophony (rosin).

Processing and Performance:

• • Paints based on Lioptal B49 have rapid film formation and curing properties, along with good gloss retention and white color stability.
  • When combined with reactive melamine resins, it yields stoving enamels with good technical properties.
  • Soluble in petroleum spirits, but small amounts of aromatic solvents and/or glycol ethers for stabilization are recommended.
  • Suitable for producing coatings with excellent weathering resistance, particularly when combined with suitable long-oil alkyds.
  • Recommended dryer blends include cobalt, barium, zirconium, or cobalt, barium, zinc, with specific cobalt content recommendations.

Overall, Lioptal B49 offers versatility and performance in coatings applications, particularly in environments requiring fast drying and good technical properties.
