Polyurea Spray Coatings of Foam Filled Fenders

Polyurea spray coatings technology is one of the new developments of the last 20 years. This technology combines fast curing, even at very low temperatures, and water insensitivity with exceptional mechanical properties, chemical resistance and durability.

The development of new raw materials and improved spray equipment has made it possible to overcome the initial problems of this technology such as substrate wetting, intercoat adhesion and surface finish quality.

The latest development programs are focusing on the extension of the application fields through the introduction of MDI-prepolymers combining low viscosity with low NCO content, resulting in slower reactivity and/or higher flexibility. Alternatively, prepolymers with higher NCO-content produce coatings with superior hardness.

It is a 100% solid, fast set, spray-applied, two component aromatic polyurea elastomer. The system consists of the A component, a quasi-prepolymer rich of free NCO, and the B component, a mixture of polyetheramine, amine extenders and other additives. The unique polyurea chemistry allows this material to be tolerant of moisture and lower temperatures during application. This means that high humidity and hidden moisture in concrete has minimal effect on the application of this product.

Outstanding Advantages

• Fast cure, short downtime, but not-sagging

• Extraordinary physical properties

• Excellent bond strengths

• Moisture and temperature insensitivity during processing

• High thermal stability

• 100% solids, No VOC's and odorless

• Outstanding flexibility, high abrasion and impact resistance

• Superior weatherproofing

• No chalking and fading in long-term use outdoors

Polyurea Spray Coatings provides outstanding protection and buffer on surface of marine facilities including buoys, ship fenders, floats, dodgem boats and glass fiberhulls. It can be used for manufacture or repair the slides or other facilities in water park.

Luhang Marine Surface Buoys are manufactured from a polyethylene or EVA thermo-laminated foam core encapsulated within self-colored polyurethane out skin. Used extensively in single point mooring (SPM) systems, the three main types of support buoy are: Cylindrical Buoys, Chain Throught Buoys, Pick-Up Buoys.

Surface Buoys

Surface Buoys, Marine Buoys, Anchor Buoys
