Sikagard®-61 TZ

Epoxy splash zone coating

Sikagard®-61 TZ is a high performance solvent free, two part epoxy coating fortified with high quality self-leafing glass flakes designed to provide corrosion resistance and abrasion protection in extreme service applications. This specially designed epoxy system has very high penetrating properties, flexibility and adhesion on wet concrete and steel substrate.

  • Deep penetration into concrete surface to avoid peeling
  • High build – can be applied up to 250 microns in one coat
  • Self-leafing glass flakes for increased impermeability
  • Good resistance against mild chemicals
  • Excellent adhesion to wet surface
  • Cures under water after application
  • Cures at low temperatures
  • Excellent flexibility

Usage

Sikagard®-61 TZ is designed to provide corrosion protection for metal and concrete structures in offshore marine and petrochemical services, sheet piles, underground and submarine pipes, waste water tanks, jetty piles, underground tanks and other structural steel that requires protection against corrosion in aggressive environment. It is most suitable for use where concrete surfaces are damp and cannot be dried out. Suitable for maintenance of splash and tidal zones.  

Advantages

  • Deep penetration into concrete surface to avoid peeling

Mixing Ratio

Mixing ratio by weight

Approximately 1.08:1 (Part A:B) by weight (based on standard concrete grey colour). Mixing ratios for other colours may vary. For more information on mixing, contact Sika Technical Service Department.

Important Note:

Sikagard®-61 TZ is pre-packed in the correct proportion. Mix only full set of Sikagard®-61 TZ to avoid problems associated with curing and/or drying. Part mixing by weight is not recommended as it may affect the product performance and lead to reduce service life.

Pot Life

~60 minutes (Higher ambient temperatures will result in shorter potlife)

Waiting Time / Overcoating

Before applying Sikagard®-61 TZ on Sikagard®-61 TZ allow:

Substrate Temperature

Minimum

Maximum

30 °C

16 hours

3 days*

*Sika recommends the latter coat of Sikagard®-61 TZ be applied as soon as possible after the minimum overcoating time to reduce the risk of possible contamination to the previous coat.

Note: The times are approximate and will be affected by changing ambient conditions.

Drying Time

At 30 °C,

Dust free

6 hours

Hard dry

16 hours

Applied Product Ready for Use

7 days (full cure)
Consumption

Consumption

~3.0 m² per kg at ~200 microns Dry Film Thickness (DFT)

The DFT of the coating (including the nos. of coat) shall be specified/determined by the Engineer. 

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage.
Application steps

APPLICATION

Stir each component separately using an electric drill (~750 rpm) fitted with a paint mixer or wing type mixing paddle. Then pour the entire Part B into Part A and continue mixing for 2–3 minutes until a homogenous mix is observed. Decant the mixed material into another clean container and mix for another 30–60 seconds. Sikagard®-61 TZ is now ready to be applied on the substrate.

Important Note:

  • Mix only full set of Sikagard®-61 TZ. Part mixing by weight is not recommended. 
  • Manual mixing or hand mixing of Sikagard®-61 TZ is not recommended. Always use an electrical/mechanical mixer. 
  • Thinning is not recommended. 
  • For more information on mixing, please contact Sika Technical Service Department.

Sikagard®-61 TZ can be applied by brush, roller or spray.

CLEANING OF TOOLS

Clean all tools and application equipment with Thinner-C immediately after use. Hardened or cured material can only be mechanically removed.
