Overseas Buyer Common Pain Points Solved
1. Cheap bulk EEP from third-party traders has unstable water content, leading to pinhole & blushing after spraying → Our factory fixed index without batch fluctuation
2. Ordinary solvent high VOC aromatic solvent restricted by EU REACH SVHC, easy customs detention → EEP low VOC compliant ether ester
3. General solvent high metal ions cause wafer spot & low yield in semiconductor production → Electronic grade ultra-low ion purification process
4. Most suppliers without own workshop, price surge & out of stock in raw material fluctuation → RealSun vertical integrated production, stable supply & fixed long-term price
Industrial Application & Real Customer Cases
Coatings & Adhesive
Application: Slow-drying leveling thinner for automotive metal flash paint, industrial amino baking finish, screen printing ink, water-based PU adhesive
Pain Point: Toluene & xylene are SVHC restricted, easy EU customs seizure; fast-drying ester leads to orange peel & silver powder blackening
Real Case: European automotive paint manufacturer switched our 99.5% EEP, paint pinhole rejection rate dropped 90%, no more silver powder discoloration issue under high humidity spraying environment.
Polymer Industry
Application Dissolving medium for polyimide, high-solid acrylic & PU resin, slow volatilization during high-temperature curing to avoid shrinkage cavity & pockmark defects.
Fine Chemical Synthesis
High-boiling reaction solvent for long-time heating synthesis of drug & pesticide intermediates, excellent solubility for aromatic macromolecular raw materials.
