valokovetettavat

Valokovetettavat is a Finnish term referring to materials that cure or harden when exposed to light, typically ultraviolet (UV) or visible light. These materials are a type of photopolymer, meaning they contain monomers and oligomers that undergo polymerization when activated by light. The light energy initiates a chemical reaction, causing the liquid or semi-liquid material to cross-link and solidify.

The process of light curing offers several advantages. It is generally very fast, often taking only seconds or minutes to achieve a hard finish. This speed is beneficial for high-throughput manufacturing processes. Additionally, light-curing does not involve significant heat generation, making it suitable for heat-sensitive substrates. The curing occurs in situ, meaning the material hardens exactly where it is applied, leading to precise application and minimal waste.

Valokovetettavat find widespread applications across various industries. In dentistry, they are used for fillings, sealants, and adhesives, where their rapid curing and biocompatibility are essential. The graphic arts and printing industries utilize them for inks and coatings that require quick drying and durable finishes. They are also employed in the manufacturing of electronics for encapsulating components and in the production of adhesives for bonding various materials. The specific wavelength and intensity of light required for curing depend on the formulation of the valokovetettavat material.
