two component silicone sealant

Two component silicone sealant

Description
(1) It is a double-component silicone sealant,neutral curing sealant;
(2) Mix the part A and part B thoroughly in the volume ratio of 10:1 while using;
(3) Solidify quickly, high adhesion after solidification;
(4) Excellent endurance to high or low temperature and weather resistance;
(5) Good adhesiveness to most building materials.

Use manner
(1) Keep the surface clean and dry;
(2) Paste the low-viscosity adhesive tape on the place that needs protection. Recondition and remove the adhesive tape before the sealant becomes solidifying;
(3) Change the ratio of mixture to adjust curing speed as you need;
(4) Product applicability should be confirmed in the user’s sole judgment. Please do the compatibility test before official use to make sure that it can stick well with the substrate materials and full the interface, otherwise we are not responsible for any complaints of application;
(5) Mix part A and part B with the volume ratio of 10:1 while using.

Application
(1) Second adhesion and seal for insulating glass assembly;
(2) Adhesion and seal for glasses and windows, doors.

Restriction
(1) Should not be used as structural installation;
(2) Should not be used on the oily or oil-leaking surfaces;
(3) Should not expose the component B in the air for a long time.

Safety
(1) Keep the work field drafty;
(2) In case of contact with eyes, rinse with plenty of water and appeal to the doctor immediately;
(3) Keep away from the children;
(4) Should not touch the production for a long time;
(5) Should not contaminate food, medicines or cosmetics.

Secondary Sealant Frequently Asked Questions

What is a silicone sealant?

Silicone sealant is a versatile, flexible and durable sealant made from silicone polymers. Silicone sealants have excellent weatherability and good adhesion to a variety of substrates, which is why they are widely used to seal seams, gaps and overlaps in construction and industrial applications.

What are the key benefits of Truemei silicone sealants?

The key benefits of Truemei silicone sealants include excellent flexibility, high mobility, resistance to extreme temperatures (-50°C to 200°C), UV resistance, good adhesion to many materials (glass, metals, plastics) and long service life.

What are typical applications for silicone sealants?

Silicone sealants are used in a wide variety of construction applications including glazing systems, curtain walls, expansion joints, roofing, flashing, sanitary and plumbing applications and are great for sealing and bonding in many industrial applications.

Can silicone sealants be painted?

We do not recommend painting over silicone sealants as most paints do not adhere well to silicone sealant surfaces. There may be some specialized paints on the market today that are designed for silicone sealants, and it is recommended that they be tested over time before use.

What is the typical cure time for silicone sealants?

Cure times for silicone sealants depend on the specific product formulation, temperature, humidity and joint configuration. Typically, they will form a top skin in 30 minutes to 2 hours and achieve full cure in 24-48 hours, but deeper sections may take longer to fully cure.

How should silicone sealants be stored and handled?

Silicone sealants should be stored in a cool, dry place away from direct sunlight and heat sources. Unopened silicone sealants typically have a shelf life of 12-24 months. When handling silicone sealants, always follow the manufacturer’s instructions and use appropriate personal protective equipment (PPE).
