1.Product Overview

2 part silicone sealant-detail1.jpg

Two-part silicone sealant is a sealing material composed of two components, A and B. Component A contains polydimethylsiloxane, while Component B contains a curing agent and catalyst. After mixing, it cures, exhibiting properties such as weather resistance, high elasticity, and excellent sealing performance. It is widely used in construction, automotive, electronics, and other industries.

5.FAQ

2 part silicone sealant-detail4.jpg

Q1: What are the composition and content of the silicone sealant?

107 silicone rubber, silicone oil, and activated calcium carbonate.

Q2: What should I do if I can't use up all the sealant at once?

Mix only the amount needed. For white sealant, it is best to place a plastic bag over the opening of the container and then replace the lid for better sealing. For black sealant, simply tighten the lid.

Q3: How many square meters can one bucket of sealant cover?

It depends on the size of the spacer bar. Larger spacer bars require more sealant. A 16L bucket can generally cover approximately 40-50 square meters.

Q4: What causes fogging in insulating glass units?

Gaps in the sealant or desiccant exposed to the outside air for too long.

Q5: What issues can cause air leakage in IGUs?

First, check if the sealant is filled completely without gaps. Second, check if the glass has been used for too long and has become debonded or cracked. Finally, ensure the sealant is fully cured before filling with argon gas (generally after 24 hours). It is recommended to use bendable spacer bars for continuous bending when filling with argon gas.
