Cyanoacrylate adhesive gives 'instant cure'

Master Bond is introducing a high-strength 'instant cure' cyanoacrylate adhesive called MB297. In addition to high-strength bonds of up to 19.3MPa (2800psi) in shearit provides better general resistance to effects of extreme humidity. MB297 is supplied as a viscous liquid adhesive with a viscosity (at 20 degrees C) of 2000-2400cps.

Its appearance is colourlessand the refractive index is 1.48. Its service operating temperature range is from -55C to 85 degrees C.

Master Bond MB 297 cures are moisture-activated and bonds are almost instantaneously formed. It creates excellent bonds to metalsceramicsplastics and elastomers. Examples of tensile shear strengths include PVC (rigid) to PVC (rigid) 19.3MPa (2800 psi)glass to glass 18.6MPa (2700psi)delrin to delrin 6.9MPa (1000psi) and steel to steel 16.8MPa (2440psi). Shore A hardness is 85.

The cured product has excellent optical clarity and is resistant to many chemicals. Master Bond MB297 is available in bottles containing 9g28g and 454g (1/3oz1oz and 1lb).
