MS Polymer, The First Choice for Prefabricated Construction !

Prefabricated construction refers to a building that transfers a large amount of on-site work in the traditional construction method to the factory, and makes construction components and accessories (floor, wall, stairs, balconies, etc.) in the factory, transported to the construction site, and assembled and installed on the site through connection.

The floor, wall, stairs, balcony and other parts of the prefabricated building are fixed by splicing, and the splicing joint of the structure is an important node part of water leakage and seepage, so it is the most important thing to do a good job of waterproof sealing of the splicing joint of the prefabricated building.

1.What is MS Polymer?

MS sealant modified by silane, is a new environmentally friendly single-component sealant synthesized by a special process, and gradually solidifies into an elastomer after contact with moisture in the air. Assembled building MS sealant does not contain solvent, excellent weather resistance, no isocyanate, good extrusion, excellent displacement resistance, excellent adhesion for most building materials, etc., widely used in assembled building external wall joints and window frames and other fields of sealing, bonding, waterproof, can also be used in other scenes of joint bonding sealing.

2.Why choose MS sealant for prefabricated buildings?

Prefabricated building prefabricated parts have a certain thermal expansion and contraction, and their joints are typical large displacement expansion joints, and their displacement is affected by environmental temperature factors, so sealing waterproof materials are required：

(1) Good sealing water resistance 

(2) good bonding ability to concrete base 

(3) excellent weather resistance 

(4) High elasticity and high displacement ability to adapt to the movement ability of large displacement expansion joints

MS sealant is a product of high elasticity and low modulus, with excellent adhesion (artificial climate aging and concrete fixed elongation after soaking no damage), weather resistance (artificial climate accelerated aging 1500h no cracking and differentiation), high displacement capacity, good sealing water resistance, good extrusion, convenient construction, long service life, designed for prefabricated building sealing and waterproof system.

3.Precautions :

1. Construction should be carried out at the base material temperature of 5℃-45℃. 

2. Construction should not be carried out if the concrete base surface is not dry. 

3.It is not suitable for construction after rainy weather and heavy rain. 

4. It is not suitable for force before colloid produces adhesive force. The substrate is flammable liquid, and no fire is allowed during construction.
