BEVA 371 Adhesive Film 690mmx1m

Beva® 371 Adhesive Film 690mm x 1m A heat seal adhesive developed by Gustav A. Berger of New York which is widely used for the lining of oil paintings, heat seal facings and the making of laminates with fibreglass etc. It is applied cold and causes no contractions, expansion or softening of the materials to which it is applied making its application possible on even the most delicate surfaces. Shrinking and distortion is minimal and heat sealing can be done days or weeks after application. Since Beva® 371 is completely dry at room temperature, it is easy to reassemble fragments and secure them in the right position with a tacking iron. Beva® 371 is reversible and errors can be easily corrected even after heat sealing. It is easy to remove and can be remelted whenever needed. The large proportion of low molecular substances in the formulation enables it to maintain low viscosity when used hot or dissolved in harmless petroleum fractions. This makes impregnation and consolidation of paint layers and canvas possible at every stage of the lining process and afterwards if needed. Beva® 371 can be applied by brush, paint roller or spray without impregnation of solvents. It is possible to lower the heat sealing temperature by using Beva® 371 films half dry or moistened with sprayed on petroleum fractions.
