Product Description
MS3938, 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.
Features
1. Without 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.
Professions involved
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.

Founded in DEC. 2003, SEPUNA has been engaged in researching, manufacturing and marketing automobile sealant and adhesive for 9 years.
Since the foundation, SEPUNA Chemical has been focusing on adhesive's researching and application. Then in 2005, We acquired PUNADE technology which is from Switzerland.
Within 9 years, SEPUNA mainly develops Silicone, Polyurethane and Epoxy resin adhesives. And in the future, we will enlarge our line to Unsaturated, Natural and Acrylic Resin adhesive.
After 9 years' improvement, by the keep researching and innovation, SEPUNA is already a mature adhesive supplier with the core competitiveness.
