Description

Description EVX/169 is a two-part adhesive with very good hot tack and good initial strength, resistant to oily leathers, to PVC plasticizers as well as to water. The adhesive was specially developed for cementing soles and midsoles based on cross-linked EVA foams to all materials used in shoe manufacturing, such as synthetic uppers, oily leathers, soles of either vulcanised or thermoplastic rubber. CHARACTERISTICS Composition : polyurethane resin in a blend of organic solvents Mode of setting : release of solvent and reaction with accelerator Colour : opalescent to colourless Solvents : ketones Components : to be used with 2 to 4% of Accelerator Desmodur RFE Pot life : 4 hours with the addition of the Accelerator TECHNICAL DATA Solids content : 18 - 19% Viscosity : 1800 - 2000 mPa.s (Brookfield spindle 4, spd 50, 25°C) METHOD OF USE Surfaces preparation: EVA soles: to prepare and treat cross-linked expanded EVA soles and midsoles see “Primer EVX/3513”technical data sheet - leather uppers and leather soles should be carefully roughed and brushed. Onto leathers having high grease content or onto materials where it is necessary to improve adhesive penetration, a first coat of Primer 144F or Primer C with the addition of 3% of Accelerator Desmodur RE or RFE should be applied. For leather with high grease content it is recommended to use Primer C as first coat. - polyurethane soles should solvent wiped with ST/141 or roughed. - PVC soles should solvent wiped with ST/141. - Vulcanized rubber soles: treat with Primer AC/20 or AC23/M, in the presence of release substances it is recommended to solvent wipe with ST/141 or to rough.
