Lascaux Acrylic Adhesive 360 HV
[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 0°C. 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 (50-55°C). 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.
