Application Instructions
  • Bond strength is dependent on the of adhesive to surface contact developed. Firm application pressure helps develop better adhesive contact and improve bond strength.
  • To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified. Typical surface cleaning solve are isopropyl alcohol and water (rubbing alcohol) or water.
  • Low temperature will reduce tack. Ideal tape application temperature range is above 10°C.
