Silicone sealant is quite a broad term that is used widely,different types have different flexibility, durability, and resistance for different applications. | ||||
*General construction sealing; | *Sealing of air-conditioning and HVAC ducts and system; | |||
*Glass and metal glazing; | *Construction, automotive, marine, and industrial bonding; | |||
*Sanitary sealing; | *Sealing of expansion joints; | |||
*Door/window/roof shingle sealing; | *Sealing gutters and downpipes | |||
*Fire-rated sealing; | *Architectural caulking and grouting; | |||
*Soundproofing and dampening; | *Gaps and cracks filling for painting; | |||
*Gluing aquariums together | *Moulding into soft rubber goods of most shapes |

SILICONE SEALANT TYPES AND MODELS | ||||
High Modulus | Low Modulus | Neutral Cure | Acetoxy Cure | |
High Modulus Acetoxy | Low Modulus Acetoxy | Low Modulus Neutral | ||
Low modulus sealants allow more movement. | ||||
High modulus sealants are less forgiving and are best used for interior applications. | ||||
Acetoxy silicone sealants release acetic acid,more rigid and quick-curing,poor adhesion; | ||||
Neutral silicone release alcohol,almost no smell,better adhesion,slower cure. | ||||
