Profile

Low modulus construction pu silicone steel sealant       MS3220              

 

PUNADE MS series is a silane-modified polyurethane sealant, with the advantages of polyurethane and silicone sealants; it is a flexible sealant widely recognized as with the best overall performance, and can meet the needs of adhesive bonding and flexible sealing for a variety of occasions.

 

PUNADE MS3220 is manufactured in strict accordance with ISO9001/14001 Quality Assurance System and related protection provisions.

 

Usage

1.Good adhesion to many substrates, include wood, various metal and surface treatment (painting or plating), glass, concrete products, mortar, ceramic materials and plastics and rubber and so on.

2.Suitable for industrial bonding and fixing (such as the installation of automobile windshield, and the manufacturing of means of transportation and lift cabinets).

3. Flexible seal bonding and fixing required for medium strength and high modulus.

4. Compatibility test should be done on the actual substrates and in the environment in advance.
