Lascaux Acrylic Adhesive 360 HV
Description
[Alois K Diethelm, Switzerland] A trademark for a thermoplastic acrylic resin composed of a water-based dispersion of butyl acrylate and methylmethacrylate thickened with acrylic butylester. The minimum film formation temperature for Lascaux Acrylic Adhesive 360 HV is approximately 0C. It dries to form a film that is more flexible and elastic than 498HV. The 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 (50-55C). The emulsion can be thinned with water, but once the film is dried it is insoluble in water. Lascaux 360 HV is used as an adhesive for lining paintings and textiles.
Other Properties
Dry films: Soluble in acetone, ethanol, toluene and xylene. Insoluble in water, white spirit and ligroin.
