Urethane acrylate methacrylate resin (UDMA) is formed by reacting 2,4,4-trimethylhexamethylene diisocyanate and 2-hydroxyethyl methacrylate (HEMA). It is mainly used as a dental resin with a higher water uptake than that of bisphenol A-glycidyl methacrylate (Bis-GMA).

Resin-based materials are used in filling materials, bonding of brackets, orthodontic bands, filling canals, and temporary bridges, among others (Schmalz, 2009). Despite their high biocompatibility, resin-based materials could present adverse reactions by the presence of residual monomers or nonbiocompatible products of degradation.

2023年7月15日 · In this work, we formulate photocurable resins based on urethane dimethacrylate (UDMA) combined with three different difunctional methacrylic diluents named ethylene glycol dimethacrylate (EGDMA), di (ethylene glycol) dimethacrylate (DEGDMA) or tri (ethylene glycol) dimethacrylate (TEGDMA).

聚氨酯丙烯酸酯甲基丙烯酸酯树脂 (UDMA)是由2,4,4-三甲基己基二异氰酸酯和2-甲基丙烯酸羟乙酯 (HEMA)反应而成。 它主要用作牙用树脂，比双酚a -甲基丙烯酸酯 (Bis-GMA)具有更高的吸水性。 [1] UDMA可与二甲基丙烯酸三甘醇酯 (TEGDMA)结合，作为树脂制成复合块，用于牙科计算机辅助设计应用。 [2] 此外，还可用于降低吸水性，提高牙用复合材料的机械强度。 [3] 没有发现合适的版本？ 如果您需要特殊版本，可通过批号或批次号查找具体证书。 已有该产品？ 在文件库中 …

In this paper, fourteen resin materials, based on urethane dimethacrylate with different co-monomers such as Bis-GMA or Bis-EMA, were evaluated. TEGDMA was used as the diluting monomer. The flexural strength (FS), diametral tensile …

2022年9月1日 · In this work, we determine the optimal monomer ratios for dental resin compounds (Bis-GMA/TEGDMA, UDMA/TEGDMA and Bis-GMA/UDMA/TEGDMA) by combining three critical properties of the cured resins: degree of conversion, rate of polymerization and surface mechanical properties.

2025年3月1日 · Urethane dimethacrylate (UDMA) is a wildly utilized methacrylate resin in dental applications due to its preferable mechanical properties and water-resistance. This monomer can be used alone or in combination with other monomers, like …

2024年7月12日 · The purpose of our study reported here was to investigate the performance of urethane dimethacrylate (UDMA) based 3D printable resin systems when using N-acryloylmorpholine (ACMO) as a diluent.

Urethane acrylate methacrylate resin (UDMA) is formed by reacting 2,4,4-trimethylhexamethylene diisocyanate and 2-hydroxyethyl methacrylate (HEMA). It is mainly used as a dental resin with a higher water uptake than that of bisphenol A-glycidyl methacrylate (Bis-GMA).

Urethane Dimethacrylates are often used in light-cure systems. The UDMA, cures to form a hard, glassy surface that is low in color and is considered bisphenol A free. Various urethane dimethacrylates have been used in anaerobic adhesive applications.
