High Strength, Medium Viscosity, Rapid Curing Cyanoacrylate Adhesive for Reliable, Cost Effective Bonding

Master Bond MB302 is a high strength, rapid curing, ethyl cyanoacrylate adhesive with a viscosity of 75-100 cps at room temperature. It offers reliable, cost effective bonding at room temperature with no mixing. Only contact pressure is required after application of the adhesive. Depending upon atmospheric humidity and substrates to be bonded, MB302 will harden in between a couple of seconds to one minute. Adhesion to metals, glass, ceramics, rubbers and most plastics is excellent. MB302 has superior resistance to moderate heat, aging and many different chemicals.

  • Rapid curing at room temperature. No heat required. Most bonds formed in under a minute.
  • Bonds with only contact pressure. No clamping or fixturing required
  • Bonds well to a wide variety of substrates including metals, rubbers, most plastics and ceramics.
  • Excellent wetting action with no solvent evaporation or hazardous vapor emission.
  • High strength bonds. Tensile strengths up to 4,000 psi.
  • Good resistance to weathering.
  • Resists many chemicals including gasoline, kerosene & various oils.
  • Easily applied. Spreads evenly and smoothly. No mixing required.
  • Most surfaces require no special pretreatments.
  • Ideal for high speed production. Automatic dispensing equipment readily available.
  • Cost effective. Only minimal amounts of adhesive are needed to form strong bonds.
