Description

One of three types of room temperature vulcanization (RTV) silicones.

Acetoxy cure is likely the more commonly used of these two types of RTV silicone. It is used extensively in construction-related applications such as window installations and as expansion joints, but also in common DIY projects in residential bathrooms and kitchens. This is owing to its ability to bond to common substrates like wood and tile, and because of its fast tack-free time and resistance to high temperatures. Their non-corrosive properties, however, do place restrictions on what materials it can be used with, such as concrete.

There are several main acetoxy cure products available on the market. These include:

ASI 502 100% RTV Silicone – food grade, UL recognized sealant, NSF approved ASI 504 Multi-Purpose Silicone – bonds to common substrates, general applications ASI 600 High-Temp Silicone – red hi-temp resistance temperatures up to 600˚ ASI 505 Self-Leveling Silicone – fast skinning, self-leveling joint sealant ASI Aquarium Sealant – high tensile strength, aquatic life safe silicone
