RTV moisture cure systems for silicone
polymers
| Learn how RTV moisture cure systems for silicone polymers work
with a condensation reaction in humidity. |
Common applications:
Building sealants, bathtub caulk, roof coatings, elastomers, curable medical
adhesives, electronics adhesives, fabric and leather waterproofing coatings
Advantages
-
RTV (room-temperature vulcanizing); cure can be accelerated by increasing
temperature and humidity
-
Robust cure system
-
One-part ease of use
-
Relatively low cost
-
Good adhesion
-
Neutral cure options (alkoxy)
Disadvantages
-
Shelf- and pot-life limitations related to the potential for accidental
exposure to moisture vapor.
-
Acetoxy cure generates acetic acid, which is corrosive to metal and has an
unpleasant vinegar odor.
-
Isopropyl alcohol or lithium-based additives found in greases and
lubricants can inhibit some moisture cure products.
-
Relatively slow rate of cure.
-
Only useful for relatively thin sections due to moisture requirement; not
good for highly confined applications.
