Frequently Asked Questions

What is the difference between acetic cure and neutral cure silicone?

Acetic cure sealants release acetic acid (vinegar smell) during curing and offer strong adhesion. Neutral cure sealants are odorless and better for sensitive materials like marble and electronics.

Can your sealants be painted over?

Yes, many of our RTV and MS polymer sealants are paintable. Check product specs for compatibility with latex or oil-based paints.

Do you offer private labeling?

Yes, we provide full OEM and ODM services including custom labels, packaging, colors, and formulations.

What is the shelf life of your silicone sealants?

Unopened sealants have a shelf life of 12 months when stored in a cool, dry place away from direct sunlight.

Are your products environmentally safe?

Our MS polymer and neutral cure sealants are low-VOC and odorless, making them safer for indoor use and eco-conscious projects.
