The successful production of quality composites, coatings and adhesives requires monomers featuring low colour and acid in addition to the appropriate inhibitor, viscosity and refractive index values. A low colour raw material will enhance the appearance of the final product. The low acid value reduces the amount of inhibitor required while extending the shelf life of your product. A consistent viscosity allows you to reproduce the same product time after time.
Technical notes
UDMA-IPDI has a higher viscosity than our X850 0000, Urethane Dimethacrylate. The high molecular weight of X851 1066 results in lower polymerisation shrinkage when cured.
Our extended UDMA is commonly used in light cure systems. Its PEG 400 portion creates a more flexible polymer upon curing. Adding this product has been shown to increase the fracture toughness of UDMA.
Bisphenol A Glycidyl Methacrylate, or bis-GMA is a high viscosity resin that has been used in dental formulations for years. Our bis GMA is manufactured with low levels of BPA or bisphenol A and low colour.
To simplify your formulation processes, we provide bis GMA already diluted in a 80:20 ratio with TEGDMA. Bis-GMA and triethylene glycol dimethacrylate are commonly paired in dental formulations. All of our bisGMA products carry the lowest lelvels of BPA or bisphenol A on the market
To simplify your formulation processes, we provide bis GMA already diluted in a 50:50 ratio with TEGDMA. Bis-GMA and triethylene glycol dimethacrylate are commonly paired in dental formulations. All of our bisGMA products carry the lowest levels of bisphenol A or BPA on the market
This form of EBPADMA has 6 units of ethoxylation. Increasing the ethoxylated chain length, increases the mobility of the molecule and therefore its reactivity and degree of conversion.
This form of EBPADMA has 8 units of ethoxylation. Increasing the ethoxylated chain length increases the mobility of the molecule and therefore it reactivity and degree of conversion.
This form of EBPADMA has 30 units of ethoxylation. It has a high degree of conversion neat and when blended with bisGMA. It also offers high levels of water sorption.
This form of EBPADMA has 10 units of ethoxylation. Polymerization of this material results in a rigid polymer with high degree of conversion
