Application: all surfaces must be clean, dry, and grease-free. apply adhesive to one surface only. bring components together immediately. align perfectly â­ once joined components cannot be repositioned. maintain light pressure without movement of the joint for at least 5 seconds, do not handle until bonding time stated above has expired.as the polymerization of cyanoacrylates is initiated by moisture from the atmosphere best results will be obtained if the relative humidity is in excess of 50%.higher levels of humidity reduce the opportunity for monomer evaporation thus limiting fume build-up. if bonding is a continuous process good ventilation must be ensured. limitations: not suitable for permanent glass bonding. oily or greasy surfaces cannot be bonded. olefinic or Fluro polymers may require specialized bonding techniques. high viscosity (hvc1650)hvc16 combines high tensile strength with improved impact resistance resulting in a toughened bond. hvc16 higher viscosity enables it to be used on porous and vertical surfaces without excessive penetration or running. uses: bond it hvc16 superglue can be used for bonding:pvcu trims rubbers timbers many plastics the high viscosity is particularly suitable for use with foam products. preparation: surfaces to be bonded must be clean, dry, and free from dust, grease, oil, or any other contaminants that may hinder adhesion. application: hvc16 permits the readjustment of components before bonding commences. apply a thin film to one side only and bring it together immediately. reposition within 2â­3 seconds. maintain light pressure without movement of the joint for at least 10 seconds, do not handle until bonding time stated above has expired. clamp or hold for a few seconds. as the polymerization of cyanoacrylates is initiated by moisture from the atmosphere best results will be obtained if the relative humidity is in excess of 50%.higher levels of humidity reduce the opportunity for monomer evaporation thus limiting fume build-up. if bonding is a continuous process good ventilation must be ensured. limitations: not suitable for permanent glass bonding. oily or greasy surfaces cannot be bonded. olefinic or Fluro polymer may require specialized bonding techniques Medium viscosity (rgc2450)rgc24 is a rapid curing adhesive specially formulated to give good adhesion to most rubbers and plastics. Good humidity resistance of cured adhesive.
