Corrosion-resistant Polyurea  for Speaker Box

Description

Polyurea coating is two components spray-up elastic coating applied in dry and warm condition. Component A is a half prepolymer through the reaction between hydroxyl terminal compounds and isocyanate. Component B is a mixture consisting of amino terminal resign and amino terminal chain extender, including activator, a little bit pigments and dispersive additives.

This kind of Corrosion-resistant Polyurea is super-long durable,waterproofing, abrasion resistant and appilcable to sound boxes in various hash environments for over 50 years.Suface granulation,noble and elegant, color optional and desired visual effect. Rapid spraying with special equipment can increase the coating effeciency.It can be applied to the surface of various sound boxes, especially to suface coating,lining,wear resistant layer, decoration layer and protective layer of large outdoor sound and sound with special surface effect.
