You can use this thixotropic additive for addition cure silicones available in our webshop.
The 5 ml portion is sufficient to thicken 500 g of silicone.
Adding this agent to the components of the silicone resin they become thicker. However the gravity of the material does not change. So it’s better to use the expression: the viscosity of the silicone increases.
According to the manufacturer's recommendation both the base and the catalyst components are to be mixed with the desired and even quantity of the additives.
After 60 seconds of mixing, also the components need mixing together.
This way the mixture is going to be spreadable enough to use on vertical surfaces.
Typically, 1-3 weight % of the thixotropic additive is sufficient to achieve the desired feature. To add more would modify (weaken) seriously the technical properties of the cured silicone.
According to our own practice dosing 0.5% of thixotropic agent results an appropriate viscosity to get a well spreadable mixture.
The shelf life is minimum of 12 months in case of appropriate storage between 5 ° to 27 ° C in a air tightly bottle or syringe.
Attention: the thixotropic agent will settle after a long storage, some components will separate. Shake it well before use to eliminate sedimentation.
