Application

1. Coatings and UV curing agents: DI-TMPTA can be used as a curing agent for coatings and other industries due to its high reactivity and excellent cross-linking properties, significantly improving the adhesion, wear resistance and corrosion resistance of coatings, the hardness and chemical resistance of products, and giving materials good gloss and adhesion. Composite material curing agent (such as fiberglass products, carbon fiber prepreg).

2. Adhesives: In adhesives, DI-TMPTA, as a tackifier, can increase the viscosity and bonding strength of adhesives and enhance their durability, electronic adhesives (such as PCB board packaging glue, display optical glue), pressure-sensitive tapes (such as industrial double-sided adhesives, electronic component fixing glue).

3. Elastomers: As a modifier for elastomers, DI-TMPTA can improve the toughness, strength and wear resistance of elastomers.

4. Wood coatings and plastic coatings: It is also commonly used in wood coatings and plastic coatings such as floor paint, piano paint, furniture paint, such as mobile phone case UV hardening coating, and car lampshade coating.

5. Ink: In the ink industry, DI-TMPTA is also widely used to improve the printing effect and durability of inks, photocurable printing inks (such as packaging printing inks, label inks).

6. Optical fiber protective coatings, flexible circuit board covering films, antibacterial coatings on medical device surfaces, and 3D printing photosensitive resins.
