PU-20 Foam adhesive

PU-20 Polyurethane AdhesivePU-20 Polyurethane Adhesive, with its rapid solidifying velocity ,insolubility and infusibility and resistance to low or high temperature, is widely used as an adhesive between fireproofing door, security door as well as any kind of composite board and fireproofing material such as rock wool,ceramic fiber, extra-fine glass wool and polystyrene foam.1.Technique Index:Appearance: dark brown or brown viscous fluidDensity (g/cm3):1.15±0.05Viscosity (pa.s):8 20Dissolubility: Dissolved in acetone or ethyl acetateApplied quantity :180 200g/m2Non-volatile substance:≥94% Activation time:<2hCuring time: 4 12hAdhesion strength:1)≥15Mpa( GB6329 ,metal and metal)2)Nonmetal damage ( GB6329 ,metal and heat preservation / fireproof stuff )2. Usage Methods(1) Remove oil, dust on the cohered surface.(2) Spread the adhesive on the cohered surface by use of sawtooth scraper.(3) Spray water on the cohered surface and then cover adhering material on it together with raising pressure for solidification.(4) Wash tool with ethyl acetate solvent3. CautionThe barrel with spare adhesive should be filled with nitrogen gas and sealed to guard against upper solidification of adhesive.4.
