MS3353L, is a one-component, multi-purpose and anti-sagging elastic sealant; it can react with moisture in the air and then it is cured, to form a permanent elastomer.



Product description


PUNADE MS series is a silane-modified polyurethane sealant, with the advantages of polyurethane and

silicone sealants.MS3353L is manufactured in strict accordance with ISO9001/14001 Quality Assurance

System and related protection provisions.






1. Low VOC, silicone, plasticizer migration, or bubbles curing, with very little odor.

2. 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. 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,

6. Intolerant to concentrated organic or inorganic acid/base solution or solvent. For specific

   requirements, we will provide relevant products and advice.

7. Dealcoholized curing, no corrosion to substrates, and substrates not polluted, in line with the

   standard for stone stain resistance.





1. Specially used for marine wood floor filling and bonding, g

2. 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.

3. Suitable for industrial bonding and fixing (such as the installation of automobile windshield, and the

   manufacturing of means of transportation and lift cabinets),

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

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