There are many types of industrial coatings, from bonding and abrasive to conductive and chemical. The type of coating that is used in product creation will depend on the intended use. Here at Si-Tech, we specialize in proprietary silicone coatings for:
- Chemical
- Abrasion
- Adhesive
- Conductive
Let’s go over each one in a bit more detail.
Chemical
We use Si Coat II™, a chemical resistant coating system that we developed, designed for use in silicone rubber applications. It’s best for products that need effective protection against petroleum-based products, such as motor oil and WD40, and other chlorinated and oxidizing chemicals such as bleach and hydrogen peroxide.
The coating, homogeneous with the silicone rubber, is resilient and flexible, while at the same time being a tough chemical-resistant coating. It also resists chemical swelling and wear within many environments without sacrificing the rubber’s tensile strength.
It also happens to be a relatively inexpensive coating, which means it gives our clients a cost-effective solution to extending their product life.
Si Coat II provides protection against:
- Petroleum-based chemicals
- Oxidants and chlorine
- Lipids
- Wear
It also offers:
- Superior surface finish
- Flexible silicone base
- Seamless coating
- Total keypad surface protection
Abrasion
Abrasion-resistant coatings are best where friction wears, grinds or rubs away the product. We work with many abrasion resistant coatings, including abrasion resistant fastener coatings designed to cut back on friction and extend the life of the product. Such coatings protect metals, for instance, from seizing, galling, and other damage.
Abrasion-resistant coatings are good for the following industries and applications:
- Medical devices
- Machines
- Tools
- Laboratory instruments
- Industrial equipment
- Consumer electronics
- Aerospace
- Automotive
- Telecommunications
- Military
Adhesive
When products require hot melt or water-based adhesive coating, such coatings can offer many benefits to your material properties, including:
- Strength
- Waterproofing
- Primer to boost surface tension
- Can be reactivated with heat to adhere to other products
- Pressure-sensitive adhesives
Conductive
Many materials can be adjusted to allow for electrical conductivity, such as copper, aluminum, and molybdenum. This type of coating is designed for higher temperature applications, promoting or limiting the flow of heat or electrical current into or out of the product. They can shield products and systems from anything from Electromagnetic Interface (EMI) to anti-static protection to thermal dissipation within photocopy machine parts.
The use of this coating will depend on the application, derived from standard coating yet filled with conductive material such as nickel, graphite, copper, silver or gold. This coating can comprise a thin film deposited in a variety of ways.
