Description
[Alois K Diethelm, Switzerland] A trademark for a thermoplastic acrylic resin composed of a water-based dispersion butyl acrylate and methylmethacrylate thickened with acrylic butylester. Lascaux Acrylic Adhesive 498 20X can be thinned with water, but once the film is dried it is insoluble in water. The minimum film formation temperature for 498 20X is approximately 5°C and its initial tack is faster that 498 HV. A dry film is slightly tacky and can be used as a weak pressure sensitive adhesive or it can be activated to improve adhesion with toluene, alcohol or heat. Lascaux Acrylic Adhesive 498 20X is used as an inpainting media.
Other Properties
Dry films: Soluble in acetone, ethanol, toluene and xylene. Insoluble in water, white spirit and ligroin.
Lascaus 498-20X contains 20% Thinner X
