Polyurethane Coating for Wood Decks

A wood deck can be considered as a valuable extension of any home, and to ensure its durability and longevity, polyurethane coatings can be used. Polyurethane coatings not only provide a smooth finish to any surface, but also provide protection against corrosion, chemicals and abrasion. It is used in waterproofing and field repair as well as coating high build epoxy and inorganic zinc for synthetic sports surfaces and other industrial applications.

About Polyurethane Coatings

Polyurethane coatings have properties that make them ideal for wood decks, which include providing a high quality finish to any surface, excellent staining and chemical resistance, along with hardness and adhesion. In addition, polyurethane coatings protect against lubricating oils, hydraulic fluids and cutting oils. Polyurethane coatings can be easily textured and are available in different varieties of gloss.

100% Solids Polyurethane Coatings

Polyurethane coating usually has two components: isocyanate-rich solution and polyol-rich solution, which is also known as ASTM D16 Type V polyurethane coating. When these two components are combined, a rapid and exothermic chemical polymerization reaction occurs, which forms a polyurethane coating film.

While normally in a liquid state, the resins turn to a 100% solid film after application. "100% solids" means that the coating does not use any solvent to dissolve, carry or reduce the coating resins. Although the viscosity is reduced by using solvents, the coating's viscosity depends on the design and selection of resin components, not by the addition of a solvent. This means that an expert chemist can develop a 100% solids polyurethane coating system having a very low viscosity without the use of any solvents.

Types of Polyurethane Coatings

Different types of polyurethane coatings are currently available in the market, which include floor coatings, polyurethane coatings, conformal polyurethane coatings and stainless steel polyurethane coatings. The coatings are also used for different purposes in the plastic and polymer industries as well as other industrial sectors. Storage and Handling

Hands and tools used to handle the coatings need to be thoroughly washed with warm water immediately after using. The container should always be closed if it is not being used, and must not be refrigerated or frozen. The coating should also not be applied on windows, cars or furniture. Polyurethane coatings should be used with enough ventilation, and contact with eyes and skin must be avoided.

If the coating somehow gets into the eyes, flush it with clean water for at least 15 minutes and contact your physician. If ingested, water can be taken afterwards, but vomiting should not be induced. Polyurethane coatings should be kept out of reach of children and pets. It is important to always read and follow the safety guidelines printed on the package label or the data sheets included with the product.
