Coating Application

Protective Coatings

A protective coating is any material that when applied to a surface that will resist the service environment and prevent serious breakdown of the substrate. Imms Industrial Coatings Inc. specializes in putting a barrier between a corrosive environment and the material to be protected. Our clients have a variety of reasons to paint from corrosion control, fireproofing, waterproofing, safety, color coding, to appearance. Imms Industrial Coatings Inc. has the experience and technique to apply:

• Alkyds
• Acrylics
• Epoxies
• Polyurethanes
• Zinc Rich
• Advanced 100% solid hybrid coatings
• High heat

Levels of Coating Protection

High performance coatings protect substrates in three ways beginning with acting as a barrier. The coating protects the substrate from the effects of its environment. Secondly a coating can act as an inhibitor to assist in corrosion control. Coatings also act as an inhibitor containing chemicals that react with moisture vapor within the coating, that interact with the steel surface, in order to decrease its corrosive characteristics. Thirdly coatings can contain sacrificial properties with metal pigments that corrode first; sacrificing themselves to protect the steel substrate.

Properties of Coatings

• Chemical resistant
• Abrasion resistant
• Impact resistant
• Low moisture permeability
• Flexibility
• Temperature resistance
• Adhesion strength

Coating Specification

Imms Industrial Coatings works closely with suppliers to develop specifications that fit our client’s needs. Some factors that can influence a selection of a coating system include:

• Exposure
• Operating conditions
• Substrate type
• Ambient conditions during application
• Environmental regulations
• Time constraints

Application Methods

Imms Industrial Coatings uses three basic forms of application of high performance coatings which are by brush, roller, or spray. When selecting an application method the following considerations should be reviewed:

• Appropriate method for the coating.
• Aesthetic goals.
• Economics of the application.
• Job site environment.

Brushing: A simple method of coating application it is uniquely suited for applying coatings to small and irregular surfaces. It allows the applicator to reach hard to reach areas but will have a slower production rate.

Roller: Best suited for large flat surfaces that do not require the same appearance or coating uniformity as spraying. Rolling provides application to large areas without containment or taping. Because rolling can produce stipple marks, multiple coats are applied and right angles to each other.

Spray Painting: A good application method for most types of industrial and commercial coatings. It is well suited for high solids, inorganic zincs, and polyurethanes. There are three basic types of spraying applications.

Conventional Spray: Paint is fed to the gun tip by air pressure where compressed air atomizes the paint outside the gun tip to the surface being painted.

Airless Spray: Paint is fed to the gun by high hydraulic pressure produced by a paint pump typically 1,500 to 7,400 psi. The paint is propelled by the high pressure through a small orifice, atomizing the paint to the surface being painted.

Plural Component Spray: This system combines the components of the coating in specific volume ratios, mixes them, and then sprays the mixed coating by airless spray. Heating elements can be used to reduce curing times and help with viscosity.
