The Many Uses of Polyurethane Paint and Coatings

Polyurethane paint, also referred to as PU paint or PU coating, is a durable, highly-resistant coating used in industrial and architectural coating systems. It is popular in the marine industry and is used for numerous applications including coatings, rigid and flexible foams, and varnishes. It is also used in steelwork, concrete, wood, and other substrates.

Polyurethane is a reaction polymer, a combination of a polyol resin and an isocyanate hardener or curing agent. Essentially, a polyurethane coating is a liquid plastic which dries to form a paint-like film on an underlying substance or layer. Polyurethane paint provides durability, resistance to chemicals, water, abrasion, and temperature, as well as an attractive glossy finish. The most common application of polyurethane is as a solid foam, accounting for approximately 60% of all polyurethane produced.

Marine Polyurethane Clear Coat

Polyurethane can be used to protect a boats paint and to keep the finish on wooden marine vessels visually appealing and more durable. You can apply polyurethane over any type of paint if it is clean and prepared properly. Polyurethane coatings can be applied to exposed wooden surfaces to create a glossy finish that serves to repel water, resist corrosion, and protect from scratches, stains, and UV damage.

Blue Water Marine Mega Gloss Polyurethane

Mega Gloss by Blue Water Marine is a single component topside polyurethane enamel that can be used on fiberglass, wood, aluminum, and steel. It provides a hard protective coating for super high gloss, color retention, and long durability. Mega Gloss is fast drying which when brushed or rolled, it can also be sprayed, and offers a smooth finish, is resistant to tough chemicals, cleaning solutions and ultraviolet light.

Polyurethane Foam Uses

Sea Hawk Polyurethane Foam

Sea Hawk polyurethane foam is urethane foam that provides excellent flotation, soundproofing or insulation. Mixed 1:1 and easy to install in hard-to-reach places. Poly-U-Foam bonds to wood, metal, and fiberglass. It foams wherever it is poured and is impervious to solvents and gasoline. A 2-quart kit will yield 2.5 cubic feet of space. Available in 2lb density. It is advised not to use below 70°F.

Liquid Urethane Foam Kit

Liquid urethane foam is a closed cell foam that comes in varied sizes, most commonly 2LB, 4LB, 8LB and 16LB densities. This two-part liquid, expanding rigid urethane foam is a closed cell, pourable foam, which will resist the absorption of water. It is the ideal boat foam for structural applications as it is resistant to water penetration and can be used for flotation, insulation, casting, carving, sculpting, sign making and areas where an extremely durable (you can penetrate with a fingernail) while it cannot be dented by hand, making it ideal for support.

Pettit Easypoxy/ EZ-Poxy

Pettit EZ-Poxy is an advanced one-part polyurethane topside and deck enamel. It’s a high gloss finish flows well when applied with a brush. It is a modern one-part polyurethane topside and deck enamel. It It’s use of silicone provides a brilliant shine and easy brush-ability. Its advanced ultraviolet filters enhance the superior gloss retention and durability of polyurethane. The result is a topside finish that is exceptionally easy to apply, producing a lasting gelcoat-like brilliance with a minimum of effort. It is more economical, requires less effort, and is more forgiving than the competition.

Easypoxy’s innovative ultraviolet filters improve gloss retention and enhance the polyurethane’s durability. This results in an end product that is simple to apply and easily creates an enduring shine and superior gloss retention, similar to that of polished gelcoat. Pettit Easypoxy is available in numerous colors.

Urethane Paint

Urethane paint was created in the mid-1960s, utilizing newly developed plastics technology, and designed to be superior to enamel paint in terms of durability by mixing pigment with polyurethanes, which act as the binder to hold the pigment molecules together. Semi-gloss urethane paints have been developed, but all urethane paint will have some degree of glossiness, because the same properties that make it resilient also make it reflect light. It has become a staple in the marine and automotive industry because of its durability.

AwlGrip Topcoat

AwlGrip Topcoat is a polyester based high gloss polyurethane topcoat giving long lasting gloss and color retention. It can only be applied above the waterline of your boat by either a brush, roller, or spray. You should apply Awlgrip Topcoat in two coats of 1.5 to 2.5 mils WFT each and allow 16 hours between each coat. Sanding between coats with 280 to 400 grit paper will provide a smoother finish.
