For Impregnation/ Lamination Processing/ Coating Ingredient
Phenolic resin varnishes are used in many applications alone or blended with other varnishes. DIC has created resol phenolic resin varnish products for the following applications. We have also developed aqueous-dispersion phenolic resins with small particle diameters that excel in impregnation workability and environmentally-friendly products that contain few monomer components.
Product Examples
-
For filters
Air filters and oil filters made from filter paper impregnated with phenolic resins filter dirty air and oil to protect automobile engines.
-
For separators
By impregnating paper and glass fibers with phenolic resin, separators demonstrate excellent acid resistance and can even withstand the strong acids inside batteries.
-
For coatings
Used as a primer coating and surface coating for electrical/electronic components that use heat resistance and chemical resistance.
-
For laminates
Strong molded laminates can be obtained through lamination and thermocompression forming by impregnating phenolic resin in a paper, cloth, glass, or carbon base materials.
-
For prepreg
Phenolic resins can be used as adhesive/reinforcing prepreg by impregnating and drying various base materials. We will research prepreg resins, base material type selections, and supply prepreg according to your desired performance demands.
