SikaPower®-1200

Fast-curing, tough and high strength assembly adhesive

SikaPower®-1200 is a tough, high strength, solvent-free, thixotropic, fast-curing epoxy adhesive. It is designed for fast assembly bonding of structural composite substrates, like GFRP and CFRP laminates, as well as metallic substrates. The adhesive cures by polyaddition of the two components.  

  • High fatigue and impact resistance
  • Long open time at high temperature and humidity
  • Cures at room temperature
  • Accelerated curing and higher mechanical strength with heat
  • Good adhesion to fibre-reinforced plastics
  • Does not contain solvents or PVC

Technical Information

CURE MECHANISM

SikaPower®-1200 cures by chemical reaction of the two components at room temperature. Higher temperatures speed up the curing process and lower temperatures slow down the curing process. The final glass transition temperature, as well as the tensile and shear strengths, may be increased with higher curing temperature.

CHEMICAL RESISTANCE

In view of potential chemical or thermal exposure, it is required to conduct a project related testing.

Application

Application Information

Surface Preparation

SikaPower®-1200 adheres usually well to fibre-reinforced plastics if applied subsequently after the removal of the protective peel ply.

Surfaces must be clean, dry and free from grease, oil and dust. Surface treatment may be required depending on the specific nature of the substrates. All pre-treatment steps must be confirmed by preliminary tests on original substrates considering specific conditions in the assembly process.

Application

SikaPower®-1200 is dispensed from dual cartridges with adequate manual or pneumatic guns. Extrude adhesive without mixer to equalize the filling levels. Attach the mixer and dispose of the first few centimeters of the bead before the application.

For advice on selecting and setting up a suitable pump system, contact Sika Canada.

 

Removal

Uncured SikaPower®-1200 may be removed from tools and equipment with Sika® Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically. Hands and exposed skin have to be washed immediately using hand wipes such as Sika® Cleaner-350H cleaning towels or a suitable industrial hand cleaner and water. Do not use solvents on skin.

STORAGE CONDITIONS

SikaPower®-1200 has to be stored at temperatures between 10 °C and 35 °C in a dry place. Do not expose to direct sunlight of frost. After opening of the packaging, the contents have to be protected against humidity.
