Toughened tackifiers.DuoMod ZT-2 expands the company's line of toughened tackifier resins. This tackifier, designed for low temperature cure VARTM VARTM Vacuum-Assisted Resin Transfer Molding composites, is said to be useful for curing at ambient temperatures up to 250[degrees]F (121[degrees]C). The DuoMod ZT-2 toughener is said to follow the proven success of DuoMod ZT-1, designed for RTM (1) (RealTime Model) Refers to a system or architecture that performs operations in real time. See real time. (2) (Release/Released To M and VARTM composites cured at 250[degrees]F and above, according to the company. Like its predecessor, DuoMod ZT-2 is said to increase the fracture toughness and damage tolerance of VARTM composites, without the loss of laminate flexural flexural pertaining to the flexure of a joint. flexural deformity fixation of joints in flexion.

It is supplied in an acetone acetone (ăs`ĭtōn), dimethyl ketone (dīmĕth`əl kē`tōn), or 2-propanone (prō`pənōn), CH3COCH3 solution for easy spraying onto a variety of fabrics and fibers. It can be used with any low-temperature cure epoxy matrix resin, and since DuoMod ZT-2 is applied only to the fiber preform, it does not affect resin processing, according to the manufacturer.
