The dicyanate has good quality and low water absorbency, good mechanical quality and technological quality. It is the ideal resin of radar cover and good material of alertness configuration cheat hull. And it's also the good materials to manufacture typographical circuit board and boards used in computer, pickup camera, duplicator and television.
Cyanate resin can be copolymerized with unsaturated polyester in order to improve the material's heat resistance as well as mechanical capacity and greatly enhance its dielectric ability. It can be compounded with methacrylate resin to achieve a mixed system of excellent compatibility.

The compatibility between cyanate and epoxy resin is so high that if 20% to 30% cyanate resin penetrates into normal epoxy resin, the system can be stored as it is for weeks in conditions under 43 c. The system can be catalyzed by octoate, cycloalkate and acetacetate of copper, zinc, cobalt, or manganese, or carboxylacietate of zinc, and gets gelated in 0.2 to 20 minutes at 177 c the thermal deformation temperature of the solidified substance is as high as 180?200 c, and meanwhile, it is characterized by high mechanical intensity, low hydroscopicity, low dielectric constant(3.0), and low dielectric loss(0.002?0.005). When cyanate is cosolidified with bismaleimide resin, the vitrification temperature of the resulted material is as high as 250 c.

Our company has established stable production lines for the cyanate products of hf?1 and hf?3, and our production capacity is 1,000 tons annually. We also develop and manufacture cyanate products of various chemical structures and between products according to the demands of our clients.
