Polyurea Decorative Coating For Film Props

Product Item : PS500E
Category： Spray Polyurea Coatings
High-end loudspeaker enclosures used in theaters, auditoriums, and other large venues are typically constructed from timber. Protecting and enhancing the appearance of these wooden structures has long been a challenge for manufacturers, who have tried various solutions with limited success. PS500E provides an effective solution to achieve the desired protective and decorative results.

1.Description:

PS500E is a 100% solids, aromatic spray polyurea elastomer. It forms a perfect bond with wood substrates, making it an ideal protective coating for high-end speakers used in theaters, cinemas, auditoriums, conference halls, and other public venues. This coating effectively safeguards speakers against collision and abrasion damage, while also preserving their acoustic integrity.

2.Features:
● Without any thinner, environmental protection,high performance of resistance to acid,alkali,salt,sulfide
● Elongation, high flexibility, can adapt to the basic cracks and slight deformation;
● Good aging resistance
● Fast curing, can be sprayed on any surface, slope, vertical surface;
● Convenient construction, spraying a film.
