Product Description
MS996 high Performance Low Modulus Modified Silicone Sealant
MS996 Modified Silicone Sealant is a high performance, low modulus, one component, neutral room temperature curing, formaldehyde-free and isocyanate-free, environmentally friendly construction sealant. It has excellent bonding properties for most building materials such as precast concrete units, fiber cement boards, stone, ceramics, aluminum, and aluminum-plastic panels, etc. It can be widely used in joint sealing of prefabricated concrete construction and joint sealing of general buildings, with excellent weather resistance and waterproof performance.
FEATURES & BENEFITS:
• Healthy and environmentally friendly, free of formaldehyde and isocyanate, solvent-free, non-toxic and tasteless, ultra-low VOC
• Easy to use, can be applied with a conventional caulking gun, one part and no mixing required
• Surface paintability, compatible with most architectural coatings
• Non-pollution, no pollution to porous substrates such as stone and concrete, Overcome the shortcomings of ordinary silicone sealant which easily contaminate the substrate
• Excellent movement capability, can accommodate ±50% movement in a properly designed joint
• Excellent weather and aging resistance, long-term superior tensile, compression and shear stress relaxation, ensuring seal durability and excellent water resistance
APPLICATIONS:
• Joint seals of prefabricated building exterior wall
• Joint seals of prefabricated building balconies
• Waterproof and leak-proof for building roofs
• Caulking and Sealing of interior joints
• Many other industrial and architectural uses

USABLE LIFE AND STORAGE:
When stored at or below 27°C in the original unopened containers, it has a usable life of 12 months from the date of production.
JOINT DESIGN:
The correct Joint design reduces stress on the sealant, provides optimum sealant movement, facilitates sealant application, and reduce the cohesive failure of the sealant and reduce the risk of cracking.
• The width and depth of the joint should be no less than 6 mm respectively
• For larger joint, the width of the joint should be greater than the depth of the sealant
• Avoid three-sided bonding and use a backing rod or tape on the bottom of the joint
PRECAUTIONS:
• When bonding cement and concrete substrates, the substrate must be completely dried and cured for 7 days before applying sealant, otherwise it will affect the bonding performance
• Temperature and humidity will affect the curing performance of the sealant. When the surface temperature of the substrate is lower than 4 °C or higher than 40 °C, it is not suitable for applying sealant
• Keep the product out of reach of children
• Avoid contact with eyes and skin before sealant curing. If contact with the skin, first scrub with soapy water or alcohol, then rinse with water; if contact with eyes, first rinse with plenty of clean water, if necessary, seek medical attention immediately
• Before using, please read the safety data sheet of the product to obtain the safety data of the product
