Acid Silicone Sealants for Bathroom And Aquarium

100% acid silicone sealant belongs to a single-component, acid-curing adhesive that cures quickly and exhibits excellent mechanical properties, good elasticity, and can be used under a wide range of temperatures. It absorbs moisture from the air to cure and provides good adhesion to general glass and aluminum alloys. It is suitable for sealing aquarium structures and industrial applications

HM-SA-AA100 Acid type Silicone sealants

Acidic silicone sealant is a one-component sealing material that cures upon contact with moisture in the air. 


It is easy to operate and does not require mixing before use. Construction can be carried out using a manual or pneumatic caulking gun. Before applying the sealant, ensure that the substrate surface is dry and free from contamination such as oil, grease, and dust. After applying the sealant, the surface should be smoothed before a skin forms on the surface of the sealant. When designing the joint, it is important to avoid three-sided adhesion of the sealant.
