Coatings at SiTech

At SiTech, we offer proprietary silicone-based coating systems that are specifically engineered to enhance the performance and durability of silicone rubber keypads and components. Our coatings form a cross-link bond with the silicone rubber, ensuring that the coating becomes an integral part of the keypad itself. This bond prevents cracking, peeling, or degradation over time, maintaining the genuine silicone feel while providing exceptional protection against wear, chemicals, and environmental factors.

With Si Coat I for abrasion resistance, Si Coat II for chemical protection, and Si Prime for superior bonding solutions, SiTech delivers comprehensive coatings that ensure long-lasting, reliable performance. The silicone-based nature of our coatings allows for flexibility and durability, ensuring that the keypads maintain their soft, tactile feel, while also protecting against the harshest conditions across a variety of industries.

These industries include:

Si Coat I: Abrasion-Resistant Coating

Si Coat I is a high-performance, abrasion-resistant coating developed for applications where wear protection is critical. This coating offers exceptional durability, ensuring that your silicone keypads and components maintain their appearance and functionality throughout their lifespan. In independent lab tests using an RCA abrasion wear tester, Si Coat I exceeded industry standards by more than 20 times, providing long-lasting protection in demanding environments.

Key Benefits on Si Coat I:

For applications requiring superior wear protection, Si Coat I ensures that silicone keypads and components retain their consistent look and feel without degradation, even in high-usage environments.

Si Coat II: Chemical-Resistant Coating

Si Coat II is designed to provide protection against chemicals, including petroleum-based products and oxidizing agents. This coating forms a durable, flexible cross-link with the silicone rubber, creating a protective barrier that resists chemical exposure without compromising the intrinsic properties of the silicone.
Si Coat II is ideal for environments where silicone keypads and components are exposed to chemicals, extending the life of the product.

Key Benefits of Si Coat II:

When your product requires protection from chemicals and harsh environments, Si Coat II offers an affordable and effective solution.

Si Prime: Advanced Coating System for Silicone Rubber Bonding

Si Prime is a specialized coating system designed to bond silicone rubber to various surfaces, particularly in the membrane switch industry. It provides a cost-effective solution for bonding silicone rubber to polyester switches, offering an alternative to mechanical fastening methods. A thin layer of Si Prime applied to the underside of a silicone rubber keypad creates an effective bonding barrier between the silicone surface and acrylic adhesives, such as the 3M™ 350 series.

In independent lab tests using the ASTM D-3330 standard, Si Prime demonstrated over twice the bonding strength of traditional silicone/acrylic adhesive systems, making it the preferred choice for reliable, long-lasting bonds in elastomer keypad applications.
