FAQ
Frequently Asked Questions
What is the difference between epoxy resin and polyurethane resin?
Epoxy resins typically achieve high strength, good chemical resistance, and low shrinkage. They are frequently used for structural applications and electronic potting. Polyurethane resins such as SILIRESIN cover a spectrum from flexible to rigid and are easy to process: typical applications include mold making, model making, prototyping, and decorative applications. The values in the technical data sheet are crucial: mixing ratio, pot life, hardness, shrinkage, and media contact.
Which resin is suitable for LED potting?
Optical clear resins are suitable for LED encapsulation: they offer high transparency and low yellowing tendency; specific values can be found in the technical data sheet. For applications with high temperature cycling, silicone potting compounds are often the more robust choice. Relevant factors include layer thickness, exothermicity, operating temperature, and adhesion. We recommend conducting a suitability test on the actual component.
What is Acrystal?
Acrystal is a mineral casting system based on acrylic resin. Powder and liquid resin are mixed and, after curing, result in a stone-like material. Ideal for sculptures, facade elements, decorative objects, and prototypes. Easy to work with, sandable, and paintable.
