MB297 High-Viscosity Ethyl Cyanoacrylate
Description
A high-strength instant-cure cyanoacrylate adhesive called MB297 provides better general resistance to the effects of extreme humidity. MB297 is supplied as a viscous liquid adhesive with a viscosity (at 20°C) of 2000-2400 cps. Its appearance is colorless, and the refractive index is 1.48. Its service operating temperature range is from -65 to 185°F.
Master Bond MB 297 cures are moisture activated and bonds are almost instantaneously formed. It creates excellent bonds to metals, ceramics, plastics, and elastomers. Examples of tensile shear strengths include PVC (rigid) to PVC (rigid) 2,800 psi, glass to glass 2,700 psi, delrin to delrin 1,000 psi, and steel to steel 2,440 psi. The Shore A hardness is 85. The cured product has excellent optical clarity and is resistant to many chemicals. Master Bond MB297 is available in 1/3 ounce, 1 ounce, and 1 lb bottles.
