Lascaux Acrylic Adhesives 360 HV and 498 HV are thermoplastic copolymer butyl-methacrylate dispersions thickened with acrylic butyl-ester. Lascaux Acrylic Adhesive 498-20X is the same thermoplastic copolymer butyl-methacrylate dispersion, however it is thickened with 20%xylene. They are all water-thinnable, but insoluble in water after drying. Once dry they are permanently soluble in acetone, toluene and xylene, but insoluble in White Spirit, VM & P Naphtha.
LASCAUX ACRYLIC ADHESIVE 360 HV is extremely elastic. The dry film remains permanently tacky, and can be used as a contact adhesive when doing hot-sealing linings. It has a setting temperature of 122°F/50°C.
LASCAUX ACRYLIC ADHESIVE 498 HV has a strong elongation at break. It is a somewhat harder and not as tacky as Lascaux 360 HV. It is suitable for wet and dry applications (reactivation with solvents). This is the standard type for linings.. It has a setting temperature of 160°F/72°C.
LASCAUX ACRYLIC ADHESIVE 498-20X is especially suited for strip-lining. It has a setting temperature of 160°F/72°C. Additional application information is available upon request.
