Certificate of Analysis-COA 

 Applications 

1. Co-Agent For Peroxide-Cured Elastomers: Formulators use this trifunctional methacrylate as a Type I co-agent in peroxide cured EPDM, EVA, CPE and thermoplastic vulcanizates, where it supports higher crosslink density and helps hold compression set and heat ageing performance in the finished rubber part.

2. Auxiliary Crosslinking Agent For XLPE Power Cable: In photon initiated and peroxide crosslinking of polyethylene cable insulation, added TMPTMA introduces polar groups that act as deep charge traps, and published research reports improved DC dielectric performance together with better water tree resistance.

3. Trifunctional Crosslinker For UV And EB Curing: With three methacrylate groups per molecule it builds dense networks in radiation curable coatings, printing inks and adhesives, curing fast and forming hard, scratch resistant films with good solvent resistance while keeping formulation viscosity low.

4. Monomer For Photopolymer Plates And Photoresists: It is used in photopolymer printing plates and in photoresist and microelectronic formulations, where a trifunctional comonomer of controlled reactivity supports imaging definition and durable cured films in optical and electronic materials.

5. Adhesion Promoter For PVC Plastisols And Polymer Supports: It works as an adhesion promoter and comonomer for PVC plastisol and plasticiser systems, and it is used to build macroporous poly(glycidyl methacrylate co TMPTMA) beads with controlled pore structure for functional polymer media.
