A polymer is a large molecule, or macromolecule, composed of many repeated subunits. Due to their broad range of properties both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass relative to small molecule compounds produces unique physical properties, including toughness, viscoelasticity, and a tendency to form glasses and semicrystalline structures rather than crystals
Clear Sealant based on SPUR Polymer is A hybrid polymer sealant cures on exposure to moisture vapour to form an elastic rubber. It have the following advantages:
This product can be removed before curing by the general solvent, such as ethanol, dimethyl carbonate. After curing can only be removed by mechanical means
Because this product is moisture sensitive, If unopened and stored at 4℃-30℃ dry environment, the shelf life is 12 months. Use it as soon as possible if opened, the remain products should be resealed and stored at 4℃-30℃ dry environment. But if shelf life expired, you can still use it only after your positive confirmation of production performance.
