Examples of powder resols for adhesives: Strong bonding with high adhesion. Demonstrates true value in heated and high-stress environments. Suitable for wood-based materials, heat-resistant adhesives, and more.
Powdered resol resin (pure resol) is a powdered form of resol-type phenolic resin with an extremely low amount of monomers. It not only suppresses odor generation but also complies with regulations (not classified as a toxic substance under the Poisonous and Deleterious Substances Control Law). We offer a range of grades that provide various benefits such as improved workability and mixability, tailored to specific applications and requirements. This time, we would like to introduce a case study utilizing powdered resol resin as a heat-resistant adhesive. 【Case Study】 Target: Adhesion of wood-based materials and composites Role: Adhesive binder for areas requiring high strength and heat resistance Reason: Forms a strong network structure through thermosetting, resistant to degradation from water and chemicals Effect: Improved durability of adhesive lines, prevention of delamination from joints, provided as a powder with good workability *For more details, please download the PDF or contact us.
