SikaHyflex 600 is a 1-component, moisture curing, low-modulus elastic weather sealant. SikaHyflex-600 is supplied in a transparent colour, in a box of 20.
Designed for applications where the appearance of the sealant is important (translucence look), SikaHyflex 600 is particularly suited as a sealant for store fronts, glass partition walls and other such applications.

Joint Design
The joint width must be designed to suit the joint movement required and the movement capability of the sealant. The joint width shall be ≥ 6 mm and ≤ 45 mm. The joint depth shall be ≥ 6 mm and ≤ 15 mm. A width to depth ratio of 2:1 must be maintained (for exceptions, see table below).
Typical Joint Dimensions
| Joint Width [mm] | Joint Depth [mm] |
|---|---|
| 10 | 6 |
| 15 | 8 |
| 20 | 10 |
| 30 | 15 |
| 45 | 15 |
All joints must be correctly designed and dimensioned in accordance with the relevant standards, before their construction. The basis for calculation of the necessary joint widths are the type of structure and its dimensions, the technical values of the adjacent building materials and the joint sealing material, as well as the specific exposure of the building and the joints. For larger joints please contact Sika or Rawlins technical service on 0113 2455450 (option 2) or send a message to [email protected].

Substrate Preparation
The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. The following priming and/or pre-treatment procedures shall be followed:
Non-porous substrates
Float glass, coated glass, anodised aluminium and stainless steel have to be pre-treated using Sika Aktivator 205, Sika Aktivator 100 or Sika Cleaner P.
Powder coated and PVDF coated metals have to be pre-treated using Sika Aktivator 205.
For details like application and flash-off times refer to the most recent PDS of the respective pre-treatment product.
Porous substrates
Concrete, aerated concrete and cement based renders, mortars and bricks shall be primed using Sika Primer 3 N or Sika Primer 210. For details like application and flash-off times refer to the most recent PDS of the respective pre-treatment product.
Adhesion tests on project specific substrates must be performed prior to application. For more detailed advice and instructions please contact Sika technical service.
Note: Primers are adhesion promoters. They are neither a substitute for the correct cleaning of a surface, nor do they improve the strength of the surface significantly.
Application Method/Tools
SikaHyflex 600 is supplied ready to use.
After the necessary substrate preparation, insert a suitable backing rod to the required depth and apply pre-treatment if necessary.
Insert a foil pack or cartridge into the sealant gun and extrude SikaHyflex 600 into the joint making sure that it comes into full contact with the sides of the joint and avoids any air entrapment.
SikaHyflex 600 sealant must be firmly tooled against the joint sides to ensure adequate adhesion.
It is recommended to use masking tape where exact joint lines or neat lines are required. Remove the tape within the skin time.
Cleaning of Tools
Clean all tools and application equipment immediately after use with Sika Remover 208 and/or Sika Cleaning Wipes 100. Once cured, residual material can only be removed mechanically.
SikaHyflex 600 cannot be overpainted.
Colour variations may occur due to exposure to chemicals or other extreme external influences. However, a change in colour is purely of aesthetic nature and does not adversely influence the technical performance or durability of the product.
Do not use SikaHyflex 600 on bituminous substrates, natural rubber or any building materials which might bleed oils, plasticizers or solvents that could attack the sealant. EPDM or other gaskets in direct contact with SikaHyflex 600 have to be tested for compatibility prior to application. For specific advice contact Sika or Rawlins technical service on 0113 2455450 (option 2) or send a message to [email protected].
Do not use SikaHyflex 600 on pre-stressed polyacrylate and polycarbonate as it may cause environmental stress cracking (crazing).
Do not use SikaHyflex 600 to seal joints in and around swimming pools.
Do not use SikaHyflex 600 for joints under water pressure or for permanent water immersion.
Do not expose uncured SikaHyflex 600 to alcohol containing products as this may interfere with the curing reaction.
