Clear Acrylic Powders. Three different formulas with different handling characteristics:
401 Ortho Powder Clear - Original non-slumping powder. Gels quickly, but has less clarity.
416 Super Fine Splint Polymer - JBC developed the new formulation to bring the properties of both the 411 and 421 polymers to create one great product. This 416 is still a super fine, high clarity polymer, but with the better stacking characteristic of the 421, helping to eliminate the slip and slide of the 411.
50/50 Ortho Powder - Blend of Ortho Powder & Clear Splint Powder. This yields more clarity and more working time than the splint resin and less slump properties from the Ortho Powder Clear resin.
