This new tape combines advancements in adhesive technology with years of industry knowledge to provide window manufacturers with exceptional performance that meets or exceeds industry standards.

Features

• High performance acrylic adhesive system
• 45 mil closed cell polyethylene foam construction
• 3 mil blue poly liner

BENEFITS – The ARclad® Advantage

When applied in accordance with ARclad® application guidelines:

• Exceptional adhesion to the broad range of substrates commonly used across the industry without the need for abrasionor other surface treatments
• Optimum balance of performance properties which resist the forces that work to pull the grille away from the sash:
  • Variances in expansion and contraction rates of the grille substrates vs. the glass
  • Use of the grille to raise and lower the window
• Co-extruded smooth coat foam allows superior wet-out of the tape to the glass surface, ensuring a watertight bond
• Custom-developed adhesive polymer which resists
  • Temperature extremes 
  • High humidity
  • UV degradation
  • Cleaning solutions*
• Silane coupling agent is not required – eliminating the cost, risk, resources and time associated with silane use
• 10-year limited warranty*Ammonia or alcohol-based cleaners are recommended. Citrus oil cleaners and muriatic acid brick treatment should be avoided with ARclad® 8645-78 and any other adhesive product.
