"Silicone is great, but it just won't stick." 🛑
We hear this from engineers every day. And they are right—silicone's low surface energy typically requires expensive primers or additional surface preparation to achieve reliable bonding.
But what if you could bond silicone as easily as plastic?
Compo-SiL® changes the rules.
Our patented technology adds an ultra-thin modified layer to the silicone base, raising its surface energy from 24 mN/m to 38 mN/m.
💡 The Result:
You can now use standard PUR (Polyurethane Reactive) adhesives or HMA (Hot Melt Adhesives) to bond silicone to:
Textiles 👕
Metals ⚙️
Plastics 📱
No special machinery. No hazardous primers. Just seamless integration into your existing line.

Compo-SiL® technology has been successful in enhancing the silicone adhesion problems by having an ultra-thin polyurathane modified layer above silicone that enhances the surface energy to 38 dynes/cm. Although there are other solutions available for silicone adhesion like plasma techniques and oth...
