Elastic adhesiveSuper X series

Elastic adhesive | Super X

Cemedine Super X is an innovative one-part, quick cure adhesive with three key features: "Pressure-sensitive adhesion", "Elastic adhesion" and "Solvent-free adhesion", which are the ideal properties of adhesives. It is used around the world.

Super X No.8008

Super X Gold No.777

SX720 (UL94 V-0 Certified)

Features

Multi-purpose adhesive for high-performance bonding of numerous materials.

Super X products allow for adhesion of various types of plastics, rubbers and ceramics over an extensive range, and also over different types of metals. These products provide excellent adhesion over a very extensive range of materials, eliminating the need for selecting a particular adhesive for each type of material, as in the case of conventional adhesives.

One-part solventless type providing quick curing at room temperature

Curing reaction is caused by moisture absorbed from the air. Pressure-sensitive range is reached in this curing process about 10 min after application. If adherends are put together during this time, they bind instantaneously as in the case of rubber contact adhesive, eliminating the need for temporary fixation. Easy-to-use, safe, and clean adhesive featuring one-part solventless capable of quick curing at room temperature is provided.

High durability

Super X as elastic adhesives does not peel off. Once materials are adhered, Super X provides durability in the range from low temperature (-60°C) to high temperature (120°C). Because of the rubber state of the hard film, the Super X sufficiently follows expansion, shrinkage and other changes of adherends.

Siloxane-free

There is not including low molecular weight cyclosiloxane. (D3 to D10 Cyclosiloxane compound)

Application

  • For bonding application that requires initial rise strength.
  • For bonding applications of dissimilar materials with different coefficients of thermal expansion.
  • For bonding applications that require durability, such as thermal cycling.
  • There are two ways to use: single sided and double sided.
    Please use properly depending on the material and the conditions to be attached.

[Method 1: Single-sided application]

  • In the case of porous material.
  • In the case of the bonding area is small.

[Method 2: Double-sided application (like contact cement)]

  • In the case of non-porous materials such as metal, plastic and ceramic.
  • When the initial rising adhesion strength is required, such as warped parts, adhesion to vertical surfaces, adhesion of heavy materials, etc.
