Product Introduction
Product Features
Among Desytek® crosslinking agents, R is a cycloaliphatic hydrocarbon containing multiple BCB‑active groups and is miscible with toluene; this product is a 60% solids toluene solution. It exhibits excellent storage stability while maintaining high reactivity, and upon curing delivers superior surface smoothness, thermal resistance, low dielectric constant and dielectric loss, as well as a low coefficient of thermal expansion.
App Features
As high-performance crosslinking agents, Desytek crosslinkers can undergo self‑polymerization under heated conditions and also participate in crosslinking polymerization with monomers or resins containing unsaturated bonds. This imparts excellent thermal crosslinking activity to unsaturated resin formulations, resulting in cured materials with higher glass transition temperatures (Tg) and improved thermal stability, while further reducing the coefficient of thermal expansion (CTE) and enhancing dimensional stability. The Desytek® crosslinker product line features distinct molecular structures, enabling users to select the most suitable crosslinker type through experimentation based on formulation requirements.
Product model
| DS5208 Crosslinking Agent | DS5208 is a bridged cyclic hydrocarbon compound containing multiple BCB‑active functional groups. It appears as a yellow‑green, transparent, viscous liquid and is miscible with toluene. DS5208 is supplied as a toluene solution with a solid content of 60%. The product exhibits excellent storage stability and outstanding reactivity; upon curing, it demonstrates superior surface smoothness, heat resistance, as well as a low dielectric constant, low dielectric loss, and a low coefficient of thermal expansion. |
| DS5210 Crosslinking Agent | DS5210 is a polycyclic aromatic hydrocarbon compound containing multiple BCB‑active functional groups. The product appears as a deep red, transparent, viscous liquid (approaching a solid state at low temperatures) and is completely miscible with toluene. DS5210 is supplied as a toluene solution with a solids content of 60%. It exhibits excellent storage stability and outstanding reactivity, imparting to formulation systems superior properties such as enhanced surface smoothness, improved thermal resistance, low dielectric constant and dielectric loss, and a reduced coefficient of thermal expansion. |
| DS5211 Crosslinking Agent | DS5211 is an aromatic hydrocarbon compound containing multiple BCB reactive groups attached to a benzene ring. Its structure also features unsaturated double bonds. The product appears as a yellow‑green powder, is slightly soluble in toluene, and has a melting point of 141–157 °C. After pre‑polymerization, DS5211 becomes soluble in toluene. With an appropriate melting point, it effectively prevents resin flow during processing. It can undergo self‑curing reactions and crosslink with other unsaturated resins, forming six‑ or eight‑membered cyclic structural units that impart excellent thermal resistance and dimensional stability to the material. Furthermore, the cured material exhibits an exceptionally low dielectric constant and dielectric loss, demonstrating outstanding electrical performance. |
