Frequently Asked Questions

What's the difference between neutral and acetoxy cure Dowsil sealants?

Acetoxy cure sealants release acetic acid (vinegar smell) during curing and work quickly, making them ideal for general glazing. Neutral cure sealants have low odour, won't corrode sensitive materials like mirrors or metals, and are better suited for sanitary applications and natural stone.

How long does Dowsil silicone sealant take to cure?

Skin-over time is typically 10-20 minutes, allowing for tooling. Full cure depends on depth and conditions but generally ranges from 24 hours for shallow beads to several days for deeper applications. Dowsil sealants cure from the outside in at approximately 3mm per 24 hours.

Can I use Dowsil sealant in food preparation areas?

Select Dowsil formulations meet food contact regulations and are suitable for areas where incidental food contact may occur. Always check the specific product's technical data sheet to confirm compliance with relevant standards for your application.
