ZEFIACAcrylic polymer beadsZEFIAC are acrylic polymer beads for the paste processing.
The viscosity and the storage stability of the paste can be adjusted by selecting the grade of ZEFIAC and the disperse medium. In addition, the Pre-gelling character can be given to the matrix resin.
Paste ProcessingPaste (sol) can be adjusted by dispersing to various plasticizers.
Paste (sol) becomes a tough molded article by heating.
The viscosity of paste (sol) and the intensity of a molded article can be adjusted by selecting a plasticizer.
Due to acrylic system, the color of molded article is unaffected by heat, and its weather resistance is excellent.
Pre-gelling AgentPre-gelling character can be given to the thermosetting resin such as epoxy resin, unsaturated polyester. Pre-gelling can be carried out by heating at below the curing temperature of matrix resin. Pre-gelling state is applicable to sheet of adhesive and temporary adhesive.
Stress relaxation agentThey are core-shell type polymer beads. Core is soft composition. Shell has character to swell. Therefore, stress relaxation character and pre-gelling character are given to matrix resin.
Adhesive strength of epoxy resin can be improved.
It can disperse easily to matrix resin and the viscosity stability after dispersion is also good.
