antas-332 Sellador de silicona de construcción modificada

Packaging : 600ml/sausage

Antas-332 is a one-component modified silicone sealant with room temperature curing and low modulus. It exhibits good adhesion and resistance to weather and stain. It can be brushed with paintings on the surface. Also, it’s environmental-friendly and has excellent adhesion to concrete, calcium carbonate board, fiber cement board, stone, ceramic and other porous materials. It is mainly used for waterproofing and joint sealing of wall panels on prefabricated buildings, also, could be used for joint sealing on other buildings.
Característica del producto
1. Excellent adhesion to most building materials, especially porous substrates.
2. Excellent performance of weather, aging and humidity resistance.
3. Excellent elasticity with movement capacity of 25% and tear resistance.
4. Good surface painting feasibility.
5. Good resistance to pollution and not easy to cause vertical flow pollution.
6. Low odor and environmental-friendly with low VOC and no isocyanate.
7. With wide range of temperature tolerance: from -40℃ to 90℃.
Objetivo principal
1.Joint sealing of concrete, GRC and other substrates on prefabricated buildings.
2.Joint sealing of road, bridge and runway.
3.Joint sealing of stone, ceramic board, etc.
4.Joint sealing of other building materials.
