“PLENSET” High-reliability type

The inquiry about this product

Features

Rapid Curing

They can not only be cured in a conventional oven but also by a flash heating method such as high-frequency induction heating, or IR curing. For instance, AE-300 as high temperature-resistant “PLENSET” is used to bond steel sheets is cured completely by heating with a high-frequency induction heater at 180degC within 60 seconds. It exhibits high adhesiveness and great durability after curing as quickly as any one-component epoxy resin adhesive.

High bonding strength and toughness

The adhesives of this type have high bonding strength against both tensile shear and peeling over a wide range of temperatures, and are most suitable for structural bonding and bonding between different kinds of materials. In particular, AE-450 as flexible “PLENSET” has flexibility and can be used for bonding in places where stresses are generated, such as neodymium magnets.

Long-Term Reliability

In a heat cycle test, a moisture resistance test and a high-temperature aging test, they exhibited durability on the level required of miniature motor magnets mounted in automobiles. In particular,AE-300 as high temperature-resistant “PLENSET” has high reliability, and exhibits superior adhesion retention under severe conditions.

Uses

  • Metal (steel, aluminum and other alloys) bonding
  • Motor magnet attachment
  • Coil fixation and protection against wire breakage
  • Neodymium magnet bonding
