Rubber adhesive 8000 / N Series

single-componenttwo-componentviscosity

8000/N is a two-part adhesive with long open time and high tack suitable for cold bonding of leather uppers to soles of vulcanized SBR, microcellular rubber, resin rubber (Thunit) and leather . CHARACTERISTICS Composition : polychloroprene rubber and synthetic resins in a blend of organic solvents. Mode of setting : evaporation of solvents and reaction with curing agent. Colour : light amber Solvent blend : esters, ketones, aliphatic hydrocarbons. Components : two components to be mixed prior to use. Part two is Desmodur RE, RFE, mixing ratio being 3-4% by weight to be added to the adhesive (part one). Pot life : The adhesive with addition of accelerator is to be used within 1 - 3 hours after mixing TECHNICAL DATA Solids content : 22 - 24 % Viscosity : 1800 - 2200 mPas (Brookfield spindle 4 speed. 50 at 25 °C) METHOD OF USE Surface preparation: - Leather soles and leather uppers should be carefully roughened and brushed. Polychloroprene based adhesives are not suitable for bonding oily leathers, for which polyurethane based adhesives are recommended. - Soles of vulcanized rubber should be roughened soon before using them in bonding. Soles obtained from rubber slabs, either of the expanded or of the non-expanded type, already roughened soon after manufacture might prove satisfactory even if aged up to some extent. Prior testing is therefore always recommended. Application of Adhesive: apply by brush the adhesive on to the two surfaces to be bonded. Drying of Adhesive: allow to dry 25-30 minutes so that solvents can evaporate.
