Product Description of 1,4-Butanediol dimethacrylate CAS#2082-81-7
1,4-Butanediol dimethacrylate (CAS# 2082-81-7) is a transparent fluid ranging from colorless to pale yellow. This multi-functional crosslinking monomer finds frequent deployment in dental composite materials, sealants, printing inks and diverse polymer sectors. It elevates materials’ mechanical robustness, heat tolerance and resistance against chemical erosion. MEHQ at a dosage of 200–300 ppm is generally added as its stabilizer.
