20 TWENTY Medium Viscosity Cyanoacrylate 20G
This Cyanoacrylate is specially formulated for the bonding of plastics, rubbers, wood, paper, leather, metals and other common substrates. PC 24 relies less on surface moisture for cure speed than standard cyanoacrylates. Recommended for use on close-fitting parts and fairly smooth, even surfaces. It is a medium viscosity modified Ethyl Cyanoacrylate adhesive. Suitable for bonding a very wide range of materials, including some porous ones, where a fast cure speed is required. Cyanoacrylates require surface moisture on the substrates in order to initiate the curing mechanism. The speed of cure is reduced in low-humidity conditions. Low temperatures will also reduce cure speed. All figures relating to cure speed are tested at 21oC. Typical Speed; - Steel/Steel <20 seconds, ABS/ABS <10 seconds, Rubber/Rubber <5 seconds, Wood (balsa) <3 seconds. The speed of cure of Cyanoacrylates varies according to the substrates to be bonded. Acidic surfaces such as paper and leather will have longer cure times than most plastics and rubbers. Some plastics with very low surface energies, such as polyethylene, polypropylene and Teflon® require the use of a primer.
