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.

Product of MS3220
Features of SI3350
1. Low VOC, silicone, plasticizer migration, or bubbles curing, with very little odor.
2. With a wide range of flexible bonding and durability, primer bonding-free.
3. It can be painted, polished, and bonded and repaired in a repeated manner, but necessary surface
requirements are not changed when substrates are re-bonded.
4. UV resistant, anti-aging and weathering resistance, flooding resistant and mould resistant.
5. Dealcoholized curing, no corrosion to substrates, and substrates not polluted, in line with the
standard for stone stain resistance.
6. Resistant to fresh water, sea water and usually water-based cleaning agents, and has a strong
bearing capacity to fuel, mineral oil, vegetable oil and animal fat and crude oil,
7. Intolerant to concentrated organic or inorganic acid/base solution or solvent.
8. For specific requirements, we will provide relevant products and advice.
