Provisional Bridges
Because Ribbond also bonds to acrylic, it is commonly used for making reinforced provisional bridges. For longer-term bridges, multiple layers of Ribbond make a strong stress bearing laminate structure to act as a framework. For simple provisionals, one piece is commonly used to prevent cracks from propagating through the resin past the Ribbond. Although a crack may start, the Ribbond prevents catastrophic failure and maintains the integrity of the bridges.
