These two resins have multiple uses. They were  made to be primers for the long crack resin but since they are low viscosity they can also be used  in stone breaks. They are also the point resins for a short or long crack. These resins have the highest lab tests of any stone damage resin on the market. The 90 is used in the point of the crack on a warm or hot windshield. Use of Primers in a long crack is patent protected.

     These are structural adhesives that are needed to hold the stress at the edge of the windshield. The stress is from the installation and is also called induced stress. It is this stress that caused the fracture to crack and split open the crack and cause a gap. Because of the gap and stress a structural adhesive MUST be used in this area of an edge crack. The stress is 1,000 - 3,000 psi. Use of structural adhesives in a long crack is patent protected.

Long Crack Windshield Repair Resins were brought to the industry by Ultra Bond founder Richard Campfield in 1990. These medium and thick resins were not used prior to this which is why they were able to be patented.  These resins were first field tests for years and then passed the same federal tests required of a new windshield. This is also the only known resin to hold up in a rollover crash and not break lose, hence the name Ultra Bond. For lab and field tests on these resins go to  www.ultrabond.com.
