Technical Specifications У 24.3-24010285-001:2002
Resin 188 is a solution of glyphtal resin in toluene, solvent or xylene, as well as mixure 90:10 by weight of xylene, solvent or toluene. The resin is modified by semidrying oils.
Application: a superior quality shall be used to produce colourless nitrolacquers and white nitro enamels, a first grade shall be used to produce coloured nitrolacquers and enamels.
