waterborne coatings

Due to health risks and environmental considerations involved in the use of solvent-based lacquers, much work has gone in to the development of water-based lacquers. Such lacquers are considerably less toxic and more environmentally friendly, and in many cases, produce acceptable results. More and more water-based colored lacquers are replacing solvent-based clear and colored lacquers in underhood and interior applications in the automobile and other similar industrial applications. Water based lacquers are used extensively in wood furniture finishing as well Waterborne technology has advanced significantly in recent years. Wurdack stays ahead of the competition through a commitment to investing in laboratory time and comprehensive testing of the newest raw materials, often before they become commercially available. Through these efforts Wurdack has established itself as a company attentive to the evaluation and testing of new products for our clients. Waterborne systems are those systems which are thinned or cleaned up with water or which contain water as an active component. These include acrylic lacquers, polyurethanes, enamels, and epoxies as well as latex coatings. They can be air-dry or baked systems, single or two-component.

Acrylic Coatings

Acrylics can either be lacquers or reactive systems. They have excellent clarity, UV resistance, and have hard finishes. They are either air-dry or baked systems. Specializing in the manufacturing of acrylic coatings & paints for substrates ranging from plastics of all types to glass to wood to all metals, both primed & un-primed. Features include UV resistance, hardness & excellent clarity. Offer both air dry & baked systems. Applications include music, sport, aircraft, cosmetic & leisure industries Lacquers using acrylic resin, a synthetic polymer, were developed in the 1950s. Acrylic resin is colourless, transparent thermoplastic, obtained by the polymerization of derivatives of acrylic acid. Acrylic is also used in enamels, which have the advantage of not needing to be buffed to obtain a shine. Enamels, however, are slow drying. The advantage of acrylic lacquers, which was recognized by General Motors, is an exceptionally fast drying time. The use of lacquers in automobile finishes was discontinued when tougher, more durable, weather- and chemical-resistant two-component polyurethane coatings were developed. The system usually consists of a primer, colour coat and clear topcoat, commonly known as clear coat finishes. It is extensively used for wooden finishing.

Enamel Coatings

An enamel paint is a paint that air dries to a hard, usually glossy, finish. In reality, most commercially-available enamel paints are significantly softer than either vitreous enamel or stoved synthetic resins. Some enamel paints have been made by adding varnish to oil-based paint. The term sometimes refers to oil-modified polyesters that were introduced in the early 1930s. The oil is required to stop or enhance the crosslinking of the paint in order to achieve sufficient flexibility of the paint film. Typically the term "enamel paint" is used to describe oil-based covering products, usually with a significant amount of gloss in them, however recently many latex or water-based paints have adopted the term as well. The term today means "hard surfaced paint" and usually is in reference to paint brands of higher quality, floor coatings of a high gloss finish, or spray paints. Enamels are thermosets based on oils and fatty acids. They exhibit a broad range of properties. They are used on everything from wood doors to metal. Baking enamels are amino resins with increased chemical, UV, and abrasion resistance over their air-dry cousins. They are very durable finishes primarily used on metals.

SPECIAL PURPOSE COATINGS

Sometimes a coating with a "special effect" is in order. These effects span the range from metallics, irridescents, transparents, fluorescents or phosphoresents. If you want your coating to sparkle, shine, or glow, we can put the package together to get the effect you want. Texture is another desired effect. Whether a wrinkle, soft touch, non-skid, or spatter effect is requested, Wurdack has experience in formulating these effects creating quality coatings for our clients. Multi-color, crackle, and spatter finishes with a variety of effects may be developed for any application. Some coatings require a specialized purpose, as an insulator, as a conductive coating, or as a tie-coat between two differing surfaces. These products can all be designed from the ground up for your specific needs. When that coating needs a bit of give, elastomeric coatings for a variety of functions are also in our skill set. Some purposes such as specific types of reflectance, weather o

CUSTOM FINISHES

Custom is what we do best! If you are looking for a solution rather than a stock answer, our approach to supplying our customers is a perfect fit. Since Wurdack is a small specialty coatings company, we must work harder and smarter to compete against the big guys. Our emphasis is on providing real value to our customers for their coating needs. There is no attempt to put a square peg into a round hole. A customer's environmental compliance needs are considered along with the production requirements and the performance specifications of the coating. We work with our customers as a team to develop precisely what they need. After the product is developed we can assist in implementing the coating system. This can involve design and consultation of a paint line in addition to assistance in the interpretation of local environmental regulations with regard to permitting and conversion to a compliant system.

Epoxy Coatings

hey are Thermoset polymers, which are primarily used for primers and interior coatings. They exhibit excellent hardness, abrasion, water and chemical resistance. They can either be epoxy enamels, two-component epoxies or baking epoxies. "2 part waterborne epoxy coatings" are used as ambient cure epoxy coatings. These non-hazardous, two-part epoxy coatings are developed for heavy duty service on metal substrates and use less energy than heat-cured powder coatings. These systems use a more attractive 4:1 by volume mixing ratio. The epoxy coating dries quickly providing a tough, UV resistant, protective coating with excellent ultimate hardness, and good mar and abrasion resistance. They are designed for rapid dry protective coating applications. Ambient cure 2 Part waterborne epoxy coatings provide excellent physical properties in exterior applications. These products have excellent adhesion to various metal substrates. Their low volatility and water clean up makes them a natural choice for factory cast iron, cast steel, cast aluminum applications and reduces exposure and flammability issues associated with solvent-borne coatings. They are usually used for industrial and automotive uses as they are high heat resistant (as latex-based and alkyd-based paints usually burn, thus peel, with slight high heat temperatures). Polyester epoxies are used as powder coatings for washers, driers and other "white goods". Fusion Bonded Epoxy Powder Coatings (FBE) are extensively used for corrosion protection of steel pipes and fittings used in the oil and gas industry, potable water transmission pipelines (steel), concrete reinforcing rebar, etc. Epoxy coatings are also widely used as primers to improve the adhesion of automotive and marine paints especially on metal surfaces where corrosion (rusting) resistance is important. Metal cans and containers are often have an epoxy coating to prevent rusting, especially for foods like tomatoes that are acidic. Epoxy resins are also used for high performance and decorative flooring applications especially terazzo flooring, chip flooring and colored aggregate flooring. Specialize in the manufacturing of epoxy coatings & paints which are thermoset polymers used for primers & interior coatings. Features include hardness, abrasion, water & chemical resistance. Can be epoxy enamels, two-component epoxies & baking epoxies. Applications include music, sport, aircraft, cosmetic & leisure industries.

GREEN COATINGS

For over two decades Wurdack has recognized the need to produce coatings that are more earth-friendly. For new customers this is always the starting point in the evaluation of potiential coatings systems. For existing coatings it continues to be a priority to guide our customers to newer technology that has a more benign effect on the earth. Back in the beginning the technology was a bit behind the times, as the demand had not reached the level to drive research and development, but those times have changed. With more and more companies jumping on the "green" bandwagon, the options and quality of choices have truly expanded. Additional benefits of such coatings include reduced insurance cost and an added marketing benefit to the end product. Doing well by doing good is a great goal regardless of its effect on the bottom line. Let us help in this effort, and in all probability even the bottom line will be enhanced.

CELLULOSICS

Cellulosics are types of lacquers consisting of nitro-cellulose, ethyl cellulose, or cellulose acetate butyrate. They have excellent clarity and dry very quickly. They are generally used for fine furniture coatings and aircraft finishes. They can be used for substrates ranging from plastics of all types to glass to wood to all metals, both primed & un-primed & for fine furniture coatings, & aircraft finishes. Quick-drying solvent-based lacquers that contain nitrocellulose, a resin obtained from the nitration of cotton and other cellulostic materials, were developed in the early 1920s, and extensively used in the automobile industry for 30 years. These lacquers are also used on wooden products, furniture primarily, and on musical instruments and other objects. The nitrocellulose and other resins and plasticizers are dissolved in the solvent, and each coat of lacquer dissolves some of the previous coat. These lacquers were a huge improvement over earlier automobile and furniture finishes, both in ease of application, and in colour retention. The preferred method of applying quick-drying lacquers is by spraying, and the development of nitrocellulose lacquers led to the first extensive use of spray guns. Nitrocellulose lacquers produce a very hard yet flexible, durable finish that can be polished to a high sheen. Drawbacks of these lacquers include the hazardous nature of the solvent, which is flammable, volatile and toxic; and the handling hazards of nitrocellulose in the lacquer manufacturing process. Lacquer grade of soluble nitrocellulose is closely related to the more highly nitrated form which is used to make explosives.
