SikaForce®-335 GG
Self-levelling 2-component PU-grout for embedding of glass panels
SikaForce®-335 GG is a pourable, self-levelling, two-component polymer grout based on polyurethane resin. It has been designed for embedding of monolithic or laminated glass panes in U-shaped support channels for standard glass railing, frameless or postless guard rail and balcony glazing. It is suitable for indoor and outdoor applications, if sealed with Sikasil® WS product.
- Stress-free glass embedding process
- Allows homogenous load distribution
- Long pot-life, easy to use
- Room temperature curing
- Solvent-free

CURE MECHANISM
The curing of SikaForce®-335 GG takes place by a chemical reaction of the two components. Higher temperatures speed up and lower slow down the curing process.
CHEMICAL RESISTANCE
In case of chemical or thermal exposure, conduct project related testing.
Application
METHOD OF APPLICATION
Consult the General Guideline “Glass Embedding” for construction details and dimensions prior to the product application.
Surface preparation
Surfaces must be clean and dry.
Application
The procedure for manual application is as follows:
Stir the base part thoroughly until it is mixed homogeneously. Add the hardener in the specified ratio in the base part and stir until a homogeneous mixture is obtained. Apply before reaching half of the pot-life and join parts together within the open time. Consider that if mixed in bigger masses the exothermic reaction can influence the pot-life and open time significantly.
Prevent adhesion to glass with a release agent or bond breaker.
Removal
Uncured SikaForce®-335 GG may be removed from tools and equipment with Sika® Remover-208. 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.
Application limits
The compatibility of setting blocks, backer rods and other accessory materials in direct and indirect contact with SikaForce®-335 GG have to be approved by Sika in advance. It is recommended to use setting blocks made of SikaForce®-335 GG.
Avoid any stress caused by thermal dilatation.
The mechanical properties of SikaForce®-335 GG change depending on service temperature.
Impacts on glass and U-shaped support channel must be verified.
STORAGE CONDITIONS
SikaForce®-335 GG base component and SikaForce®-010 hardener have to be kept between 10 °C and 30 °C in a dry place. Do not expose it to direct sunlight or frost. After opening of the packaging, the content has to be protected against humidity.
Minimum temperature during transportation is -20 °C for max. 7 days.
