Areas of Application
SikaPower®-4720 is suitable for panel bonding with exposure to high dynamic stress areas such as door skins, rear body panels, roof skins or quarter panels. Use for body structure parts only in combination with spot welds or rivets, following vehicle manufacturers recommendation. Common substrates are metals, particularly aluminum (incl. anodized and rolled), cold rolled steel and FRP-substrates. Metal sheets assembled with SikaPower®-4720 (in uncured stage) can be spot welded. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.
Surface preparation
Abrade metals surfaces to bare metal, clean and degrease with Acetone or Heptane. Additional surface treatment depends on the specific nature of the substrates and the manufacturer process.
