Description

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 120ºF (49ºC) and can be post cured to achieve a high glass transition temperature of 425ºF (218ºC). 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.

Benefits

• 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 effect during curing and ability to use low cost master
model materials.
• Nano technology delivers outstanding toughness & high Tg. (425ºF or 218ºC) 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.
