Numerous Advantages of Polyurethane Prepolymers

Although there are numerous products in the market that are being used for various commercial and personal projects but Polyurethane Prepolymers have their own value and importance. The latest series consist of aromatic polyurethane prepolymers generally used in the production of coatings, sealants, and adhersives.
Under the process, curing takes place by direct contact with atmospheric moisture to deliver tough, resilient polymers with outstanding durability.
The various applications include:
• Sports and Playground Surfacing
• Rubber Crumb Binder
• Dust sealer for Concrete
• Hard, Tough Floor Coatings
• Polyurethane Sealants
• Polyurethane Adhesives
Another kind of prepolymer consists of alipathic polyurethane prepolymers generally used in the production of sealants, expansion joints, coatings and adhesives.
Here curing takes place by direct contact with atmospheric moisture by use of an oxazolidine latent hardener.
The typical applications of this polymer include:
• Adhesives
• Sealants
• High Performance Coatings
• Block Paving Seal
• Concrete Sealer
• Wood Lacquers
