What does high modulus sealant mean?
What does high modulus sealant mean?
The meaning of high and low modulus can be explained simply: a low modulus will need a lower force to stretch it once cured and will have better elasticity and movement, a high modulus is more rigid once cured.
What is acetoxy cure?
Acetoxy cure silicones derive their name from their release of acetic acid, which gives off a strong vinegar like smell while curing. These silicones cure with the presence of atmospheric moisture and generally have a very fast cure time (24 hours) (10 min. skin and 17 min. tack) and adhere better to many surfaces.
How long does Geocel last?
Most of our products have a shelf life of one year from the date it was manufactured.
What is modulus in silicone?
High or low modulus silicone sealant refers to the tensile strength of the silicone. High modulus sealants typically contain fungicide, and are used on interior joints in damp areas such as the bathroom, while low modulus sealant is used outside in expansion joints that require more movement.
Is acetoxy silicone food safe?
RTV BLUE – produced by UK adhesives and sealants manufacturer BONDLOC – is an easily applied, one part acetoxy silicone sealant. The new sealant is possibly the only blue food safe sealant currently available and is an ideal solution to numerous applications in a food production environment.
What’s the difference between sealant and silicone?
Due to the low surface energy of cured silicones, it is almost impossible to get anything to easily stick to silicone. Because of this special glues and surface preparations are needed to bond cured silicones to another material. Sealant is a compound used to seal things. Silicone sealant is only one type of sealant.
Is acetoxy silicone safe?

How long does low modulus silicone take to cure?
Generally speaking, most silicone sealants take about 24 hours to cure completely. After this point they can be safely exposed to water, moisture, and other conditions of normal use.
What causes silicone to cure?
Before being exposed to moisture, silicone must cure. Drying refers to the initial (and generally rapid) process in which water and moisture evaporate, leaving the silicone dry to the touch. Curing refers to a more complex (and slower) process of chemical changes that occurs after silicone is exposed to oxygen.
