PL841 Chlorinated Rubber Waterline Coating

Overview
Chlorinated rubber waterline coating for ship hull waterline areas where alternating wet/dry exposure and oil resistance are required.​
Performance focus: resistance to wet/dry cycling, wave impact, and weathering, with suitability for low-temperature application.​

Composition
Chlorinated rubber resin with acrylic resin, special weather-resistant pigments, plasticizer, solvent, and additives.​

Typical uses
Protection and decoration for ship shell waterline areas.​
