Technology - Resin Development
Here at Bont, we have been conducting resin development for over 45 years. We formulated a resin that is super stiff, yet moldable at low temperatures. Furthermore, fast cure time is critical for our requirements. Additionally, we are one of the only boot manufacturers who develop their resins in-house.
Our resin softens at just 60°C (140°F), which is the lowest in the industry. As such, you can reheat our resin as many times as required. That is to say; you can heat your boot and easily mold it to your foot. Following the heating, allow your boot to set and cool for your custom mold.
Epoxy or polyepoxide is a thermosetting epoxide polymer that cures when mixed with a catalyzing agent or hardener. We control Polymerization, called curing, through temperature and the choice of resin and hardener compounds. The process can take minutes to hours.
The amount of hardener added to the resin is critically dependent on the temperature of the air and the amount of humidity. For this reason, we have a computer that mixes the resin and hardener. This computer dispenses the resin after measuring the air temperature and humidity.
Most manufacturers use a process known in the industry as pre-preg. A process that involves “pre-impregnating” resin into the carbon fiber.
Pre-preg, in virtually all applications, the carbon fiber manufacturer chooses the resin. Its a one shoe fits all kind of deal. The boot manufacturer has no way of altering the resin customize heat moldability requirements of modern boots. For this reason, many competitors require high temperatures to make their boots heat moldable. Often the boot moldability is limited, even at these high temperatures.
