Ø DESCRIPTION
CB350 Silicone Sealant for doors and windows is a one-component, neutral curing, universal silicone building sealant, specially designed for caulking and sealing of windows and doors. Silicone Sealant is extruded from packing with sealant gun when used, and it quickly cures at room temperature by reaction with moisture in the air to form a durable, flexible silicone rubber seal.
Ø CHARACTERISTICS
1 One-part, Good extrusion and thixotropy between 4℃ and 40℃, Easy to use, immediately applying to construction after squeezing from sealant gun.
2 Neutral curing, applied to metal, coated glass, concrete, marble, granite etc
3 Excellent resistance to weather, UV, ozone, water and Extreme temperatures stability
4 Excellent adhesion to most common building material without using bottom coating after cured
5 Good compatibility with other neutral silicone sealants of our company.
Ø APPLICATIONS
1 Glazing for door and window;
2 Sealing in joints;
3 Many other uses.

Ø RESTRICTIONS ON USE
CB350 Silicone Sealant for doors and windows should not be used
1 Be used as a structural sealant
2 To building materials that substrates oozing grease, plasticizers or solvents– materials, such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes, In totally confined spaces without ventilation because sealants need absorb moisture form the air for curing.
3 The surfaces being frosted or wet, the places constantly water or wet throughout the year
4 Paint surface, paint may be peeling or cracking lead to the failure of sealing adhesive
5 The surface temperature of the materials is below 4℃ or higher than 40℃

Ø TECHNICAL SERVICE
Adhesion Test
The laboratory of our factory can carry out the adhesion test for clients and give the test report that includes experimental result, recommended products, cleaning methods of the material surface and whether or not to use bottom coating of the material surface etc.
Compatibility Test:
If the accessory like foam strips, double-sided glue strip can not be compatible with silicone rubber, it may cause silicone rubber to turn colors, even lose adhesion. To avoid these problems, we provide services of compatibility test for clients. Clients can send the accessory to us by mail (or other ways), then we will carry out the compatibility test and give the test report.
Pollution Test:
We provide services of pollution test for clients. Clients can send the substrates to us by mail (or other ways), then we will carry out the pollution test and give the test report.
Ø INTERFACE DESIGN AND APPLICATION METHODS

Ensure that it is beyond the reach of children before curing. The products in the curing process will produce Methanol, so attention should be paid to ventilation in the construction and curing area, in case of too a negative impact on human beings from Methanol.
Ø ASSURANCE
Our factory will issue product warranty after purchase and determination of the construction units and projects.
Ø MAINTENANCE
Not required to maintain normally. If the seam of sealant container is damaged, seal the damaged part with sealant after removing the accumulated dirt with solvent.
