Features of Acetoxy Bathroom Sealant
Features of Acetoxy Bathroom Sealant:
Advantages:
Strong adhesion (especially to non-metallic substrates such as glass, ceramic, tile, and PVC).
Fast cure (fast surface crusting).
Excellent weather resistance.
Generally good mildew resistance (specialized bathroom sealants may contain mildew inhibitors).
Price advantage compared to neutral sealants.
Disadvantages/Limitations:
Acidity: This is its primary limitation. The released acetic acid may:
Metal Corrosion: There is a risk of corrosion to copper, brass, lead, zinc, galvanized steel, and some types of stainless steel. Do not use on surfaces that come into direct contact with these metals (such as shower enclosures with embedded metal fittings, certain faucet rims, and metal pipe joints). Suitable for use on aluminum and anodized aluminum.
Irritating Odor: A strong odor occurs during curing, requiring adequate ventilation.
Skin and Eye Irritation: Contact with uncured skin may cause irritation.
Bonding to alkaline or porous substrates such as concrete and marble may not be as stable as with neutral adhesives (acetic acid may react with the substrate).
Deepness of cure is significantly affected by ambient humidity.
