Sikaflex®-529 Evolution
Isocyanate free sprayable sealant for vehicle bodies
Sikaflex®-529 Evolution is a sprayable 1-component Silane Terminated Polymer (STP) sealant that cures on exposure to atmospheric humidity.
It is used for seam sealing of factory provided original structures (surface areas and beads) for vehicle body assemblies. It adheres well to all the materials commonly used in body shops, e.g. metal primers and paint coatings, metals, painted plastics and plastics.
Where applied, it improves the resistance against stone chip and other attacks to the car body.
- Easy to reproduces original structures
- Over paintable with various paint systems
- Very good working properties with little overspray
- Good adhesion to a wide variety of substrates
- Spray and bead application
- Low odor
- Good acoustic and damping properties
- Solvent and isocyanate-free
- Silicone and PVC-free

Usage
Sikaflex®-529 Evolution is designed for use as a sprayable elastic sealant for seam sealing, lap joints and stone chip protection in collision repair and vehicle body construction.Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-529 Evolution 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 ensuring adhesion and material compatibility.

CURE MECHANISM
Sikaflex®-529 Evolution cures by reaction with atmospheric moisture. At low temperatures the water content of the air is generally lower and the curing reaction proceeds somewhat slower (see diagram 1).

CHEMICAL RESISTANCE
Sikaflex®-529 Evolution is generally resistant to fresh water, seawater, diluted acids and diluted caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils; not resistant to organic acids, glycolic alcohol, concentrated mineral acids and caustic solutions or solvents.
Application
Surface Preparation
Surfaces must be clean, dry and free from grease, oil, dust and contaminants.
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 have in any case to be verified by tests on original substrates.
Application
Sikaflex®-529 Evolution can be processed between 5 °C and 40 °C (climate and product) but changes in reactivity and application properties have to be considered. The optimum temperature for substrate and process material is between 15 °C and 25 °C.
Sikaflex®-529 Evolution can be processed with manual, pneumatic or electric driven piston guns as well as pump equipment. For spray application use Sika® Spray (cartridges) and Sika® Jetflow (unipacks) dispensers. Other dispensers need to be checked for suitability.
Tooling and Finishing
Tooling and finishing must be carried out within the skin time of the product. It is recommended using Sika® Tooling Agent N. Other finishing agents must be tested for suitability and compatibility prior the use.
Removal
Uncured Sikaflex®-529 Evolution 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 or a suitable industrial hand cleaner and water.
Do not use solvents on skin.
Overpainting
Sikaflex®-529 Evolution can be best painted within the skin formation time.
If painting process takes place after the sealant has built a skin, adhesion 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.
