  • Fast skinning
  • Low odour

PRODUCT BENEFITS

  • Short cut-off string
  • Fast skinning
  • Low odour
  • Overhead work possible
  • Bonds well to a wide variety of substrates
  • Can be sanded
  • Can be painted
  • Resistant to ageing
  • Silicone free

Usage

Sikaflex®-227 is suitable for sealing, seam sealing, simple bonding as well as for vibration reduction and sound deadening measures in crash body repair and car body construction. Suitable substrates are metal primers and paint coatings (2-c systems), metals, painted plastics and plastics.
Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-227 on materials prone to stress cracking. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

Surface preparation

Surfaces must be clean, dry and free from grease, oil and dust.

Surface treatment depends on the specific nature of the substrates and is crucial for a long lasting bond. Suggestions for surface preparation may be found on the current edition of the appropriate Sika® Pre-Treatment Chart. Consider that these suggestions are based on experience and must be verified by tests on original substrates.

Application

Sikaflex®-227 can be processed between 5 °C and 35 °C but changes in reactivity and application properties have to be considered. The optimum temperature for substrate and sealant is between 15 °C and 25 °C.

 

Sikaflex®-227 can be processed with hand, pneumatic or electric driven piston guns as well as pump equipment. For advice on selecting and setting up a suitable pump system, contact the System Engineering Department of Sika Industry.

Tooling and finishing

Tooling and finishing must be carried out within the skin time of the sealant. It is recommended to use Sika® Tooling Agent N. Other finishing agents must be tested for suitability and compatibility prior to use.

Removal

Uncured Sikaflex®-227 can 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 Sika® Cleaner-350H cleaning towels or a suitable industrial hand cleaner and water. Do not use solvents on skin!

Overpainting

Sikaflex®-227 can be best painted after formation of a skin. Painting could be improved by treating the joint surface with Sika® Aktivator-100 or Sika® Aktivator-205 prior to paint process. If the paint requires a baking process (> 80 °C), best performance is achieved by allowing the sealant to fully cure first. All paints have to be tested by carrying preliminary trials under manufacturing conditions.

The elasticity of paints is usually lower than that of sealants. This could lead to cracking of the paint in the joint area.
