SMP581 Silane Modified Polyether Sealant Paintable 590ml For Precast Building

Introduction
SMP581 silane modified polyether sealant a one-component neutral-curing low-modulus sealant product with a joint movement capacity of class 20. The product has good bonding ability to most building materials and plastics such as concrete, stone, glass, aluminum, wood, polycarbonate (PC), etc. It can be widely used in prefabricated buildings, urban integrated pipe corridors, balconies and indoor and other fields of caulking and sealing of joints of internal and external walls of various buildings.

Product Features

• Environmental product: ultra-low VOC, non-toxic and tasteless, no pollution and no corrosion to the substrate;
• Good flexibility: low modulus, which can reduce the impact of internal stress caused by seam displacement changes on the durability of the sealant and reduce the risk of debonding and cracking. It has good flexibility and can maintain good bonding and sealing performance under the change of displacement of building joints.
• Excellent adhesion: excellent adhesion to most building materials and plastics such as concrete, stone, glass, aluminum, wood, polycarbonate (PC);
• The joint movement capacity is ±20%. For the normal expansion and shear deformation of building joints, this product can maintain the same performance and play an effective sealing and bonding effect;
• Excellent elasticity, weather resistance and fatigue resistance.
• Good paintability: the surface is paintable, and with Baiyun adhesion promoter, it can better solve the problem of decorative mortar, real stone paint and other finishing treatment on the glue surface.
