Quality Control

Every batch of our acrylic telomer is produced under strict quality management systems to ensure consistent performance. We employ advanced analytical techniques including GPC (Gel Permeation Chromatography) for molecular weight distribution and FTIR for structural confirmation. Certificates of Analysis (COA) detailing key parameters such as solids content, viscosity, acid value, and color are provided with each shipment to guarantee it meets your specific formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for 24 months from the date of manufacture. For long-term storage under inert atmosphere, please contact our technical team.
