The product is mainly characterized by its narrow molecular weight distribution, excellent insulating properties, and high flexibility.
It is widely used in potting adhesives, general adhesives, sealants, waterproof coatings, and other special adhesive applications.
Yes, the product can be hydrogenated. After the hydrogenation process, it still maintains its fluidity at room temperature and exhibits superior weather resistance.
The product comes in two distinct specification grades: one with a molecular weight of 3000 (hydroxyl value: 0.6-0.65 mmol/g) and another with a molecular weight of 2000 (hydroxyl value: 0.9-0.95 mmol/g).
For the 3000 molecular weight grade, the viscosity at 40℃ is <15 Pa-s. For the 2000 grade, it is <10 Pa-s. Both grades maintain a low water mass fraction of less than 0.05%.
