PRODUCT DESCRIPTIONSikaForce®-7800 Red and Blue are two-component polyurethane surface fillers used for final profilling and finishing of wind turbine blades prior to the application of a top paint coat. They are available in co-axial cartridge packaging for use in a standard caulking gun making them easy to extrude, mix and apply.They provide good adhesion to both polyester and epoxy GRP and are also color coded material for product identifica-tion to insure the correct product is used for the specific temperature range.
Our most current General Sales Conditions shall apply.
Please consult the Data Sheet prior to any use and processing.
PROCESSING BENEFIT• Rapid excess stock removal• Fine dust – no balling• Clog free abrasive surface after sanding• Pore free
ENVIRONMENTAL CONDITIONS• Application from +5°C to +35°C• Moisture resistance up to 80% R.H

Description
SikaForce®-7800 Red is a two
component polyurethane based profile and surface filler that works best at temperature above 15 °C. If ambient temperatures are lower than 15 °C it is advisable to use SikaForce
®-7800 Blue.
Product Benefits
- Excellent mixing, application and tooling properties
- Very good adhesion to fiberglass surfaces
- Non-sag up to layer thicknesses of approx. 20 mm
- Fast sanding time - Easy to sand, does not clog the
sandpaper
Areas of Application
SikaForce®-7800 Red is used for
profile shaping and surface filling of damaged rotor blades in the wind turbine industry. This product is suitable for profes-sional experienced users only. Tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

Cure Mechanism
The curing of SikaForce®-7800
Red takes place by chemical reac-tion of the two components. Higher temperatures speed up the curing process and lower temperatures slow down the curing process.
Environmental Resistance
In case of expected chemical or thermal exposure, we recommend a project related testing. Consult the Technical Department of Sika Industry for advice.
Method of Application
Surface preparation Usually it is necessary to prepare the substrates to ensure optimal adhesion. Based on the surface condition and type of material, physical or chemical pre-treatment may be required after the cleaning process. Advice on specific applications is available from the Technical De-partment of Sika Industry.
Cartridge application
For the cartridge application use a suitable manual or a compressed air piston-type cartridge gun. To ensure good mixing quality a static mixer of type Sulzer MixPac
®
Quadro MGQ 08-20T is to be used. Other static mixers may be suitable but have to be thoroughly tested beforehand.
Cleaning
Uncured SikaForce®-7800 Red
may be removed from tools and equipment with Sika Remover
®-
208. Once cured, the material can only be removed mechanically. Hands and exposed skin should be washed immediately using Sika
®
Handclean towels or a suitable industrial hand cleaner and water. Do not use solvents!
Storage Conditions
SikaForce®-7800 Red has to be
kept between 10 °C and 30 °C in a dry place. Do not expose to direct sunlight or frost. After opening of the cartridge, the contents need to be protected against humidity.

Mixing instruction for 2‐component coaxial cartridge
METHOD 1: APPLICATION THROUGH STATIC MIXER SikaForce®‐7800 Red can be directly applied from coaxial cartridges through a static mixer (type Sulzer
MixPac® Quadro MGQ 08‐20T)
Due to the fast curing speed the mixer open time is limited to approx. 1 min at 23°C
The tooling time at 23°C is approx. 3 min
Equipment required Unscrew and remove plastic retaining nut
Pull out blanking plug
Squeeze out approx. 10‐20 mm of filler
Place static mixer over end and…
…tighten by hand only
Start application,… …use spatula to tool filler and let material cure

METHOD 2: HAND MIXING BY SPATULA SikaForce®‐7800 Red can be mixed by hand using a spatula
Mixing by hand increases the risk of inhomogeneous mixture and may affect the material performance
The tooling time at 23°C is approx. 3 minutes (includes time required for mixing)
Equipment required Unscrew and remove plastic retaining nut
Pull out blanking plug
Squeeze out… …the required amount of filler
Homogeneously mix both components until streaks fully disappear (approx. 30 s)
Tool filler by spatula and let material cure
