Low viscosity for high-speed production
Our silicone coatings with low viscosity are ideal for high-speed production processes. They can be applied manually or automatically using spraying, flow, or jetting techniques. These materials are also a great choice if you need your coating to pass through vias or under chips.
Greater control can be achieved by high viscosity.
This type of silicone coating offers varying levels of viscosity, which allows for better regulation of flow speed and distance, thus preventing unwanted spread into restricted areas. With higher viscosity options, thicker coating layers can be achieved in a single application, and some grades can even provide a consistent coating on tall vertical surfaces.
Choose Your Cure Profile
Prostech silicone coatings are highly versatile and can be customized to suit your production line setup, volume, and application needs by offering flexible cure profiles.
Fast, moisture cure
Coatings that cure rapidly at ambient temperature offer a hassle-free and non-sticky solution, which can be put into production in under ten minutes. This makes them the perfect choice for assembly lines that require high output. The curing process can be expedited by applying heat or irradiating with ultraviolet (UV) energy, which further enhances productivity.
Moisture cure with an extended working time.
These types of silicone coatings can be cured at room temperature and allow for more time for the material to spread over larger or intricate boards. They are the favored option for situations that call for a thicker coating.
Heat cure
Heat cure Silicone coatings are often referred to as a “command cure” due to their ability to provide precise control over the cure rate. These coatings are ideal for processing operations that require a complete cure in less than five minutes. Additionally, they can minimize stress on board components during thermal cycling.
Choose your hardness
Conformal coatings made of silicones are capable of providing a lower modulus compared to any other organic material. This quality makes them perfect for reducing stress on delicate solder joints or thin wires. Moreover, silicones have a diverse chemical composition that allows for the creation of tough coatings that offer abrasion resistance similar to acrylic or urethane solutions. Whatever your application necessitates, Prostech can supply a conformal coating with the appropriate durometers to fulfill your requirements.
Highest stress relief (<15 Shore A)
The stress relief on delicate wires and dense components, which are highly vulnerable to thermal cycling, is greatly enhanced by our gentle silicone coatings.
Stress relief (15 Shore A to 40 Shore A)
Silicone coatings are the perfect substitute for fragile organic coatings, as they provide an ideal balance of stress alleviation and safeguarding against severe environmental factors, including humidity, debris, shaking, and collision.
Abrasion resistant (40 Shore A to 25 Shore D)
Coatings made of silicones in this category harden to create durable surfaces that are similar to acrylics but with the added benefit of increased flexibility. These coatings are also able to maintain their performance in extreme temperatures, both high and low.
Choose solventless Silicone
Prostech provides elastoplastic coatings that are solvent-based and have a similar hardness to acrylic. However, the majority of our silicone products are solvent-free, which is a crucial factor to consider when selecting a conformal coating. The use of solvents can lead to the implementation of safety protocols for workers, specialized equipment, and handling and processing requirements for flammable solvents, as well as compliance with environmental regulations. By opting for solventless silicone coatings, you can simplify your manufacturing operations and reduce costs and time.
