Resin infusion products
Toolfusion 3A/ 3B
High temperature infusion resin with low initial cure temperature
Toolfusion 3A/ 3B is a two part low viscosity epoxy infusion resin formulated to produce pre-preg quality, composite molds. Toolfusion 3A/ 3B
has a low initial cure temperature of 120 F (49 C) and can be post cured to achieve a high glass transition temperature of 425 F (218 C). Void
contents of less than 1% are achievable. Toolfusion 3A/ 3B will work in various RTM and VARTM processes including single and double bag
arrangements to produce autoclave quality laminates.
Resin infusion process delivers very high quality laminates with low manufacturing costs, no refrigeration
costs, no autoclave running costs.
Low initial cure temperature for low thermal expansion e ect during curing and ability to use low cost master
model materials.
Nano technology delivers outstanding toughness & high Tg. (425 F or 218 C) for long tool life and reduced life
cycle cost.
Low viscosity allows infusion of thicker and more complex laminates with fewer resin feed lines.
In comparison to metallic tools, Toolfusion 3A /3B composite tools are lighter weight for easier
manual handing.
In comparison to metallic tooling, Toolfusion 3A/ 3B composite tools have faster heat up and cool down
rates for reduced production costs.
Toolfusion 3A/ 3B composite tooling laminates have vacuum integrity for vacuum bag processing of parts in
oven and autoclave.
