Quick Details
Specifications
One Component MS Sealant for Construction Joint Sealing
MS365UV is a single-component sealant preparation based on SIPE resin, which known as MS or SMP (Silane-modified polyether) as the main component. It has black, white and gray three colors for choice. It has good flexibility, good adhesion with cement, stone and a variety of substrates, the cured sealant without bubbles.
Key Features
1. One component, excellent extrusion and thixotropy, convenient to apply2. Environmental protection, solvent-free, silicone-free, no pollution the substrate, the surface is paintable
3. Excellent weather resistance and durability
4. Excellent extrudability, easy to scratch sewing operation
5. Low modulus, good anti-displacement ability
Typical Applications
1.Waterproof sealing of industrialized housing, PC board (precast concrete) slit sealing.2.Waterproof sealing of the expansion joints of external concrete walls.
3.Waterproof sealing of the metal curtain reserved seam.
4.Waterproof sealing of cracks between the aluminum window frames and concrete, cement walls.
Technical Data Table
1. Clean and dry all substrate surfaces by removing foreign matter and contaminants such as oil dust, grease, frost, water, dirt.
2. Ambient temperature and humidity could affect the touch dry time and curing. If the temperature and humidity is too low, the curing speed will be slow. On the contrary, the higher temperature, the touch fry time is faster, make sure the construction environment temperature between 5~35°C, humidity between 50~70%RH. At temperatures below 5°C, is recommended heating the product by place in a 30~40°C environment for 1 hour (should be less than 3 hours) before use.
For cartridge
1. Cut nozzle to give the required angle and bead size
2. Pierce the membrane at the top of the cartridge and screw on the nozzle
3. Place the cartridge in an applicator gun and squeeze the trigger with equal strength
For sausage
1. Clip the end of the sausage and place in barrel gun
2. Screw end cap and nozzle on to barrel gun
3. Using the trigger extrude the sealant with equal strength
Attention of operation
1. The nodes parts can be modified and strike off to smooth by scraper or hard foam strip. Smoothen small details section with soapy water.
2. Need to do compatibility testing before painting construction.
3. Must be used in conjunction with the base surface treatment agent
