Two new additives from AXEL, MoldWiz® INT-PA33FRK (a liquid additive), and MoldWiz® INT-38F (an additive in pellet form) have recently been evaluated with excellent results.  The flow additives were loaded at 3 parts /1000 based on weight utilizing liquid or pellet feeders as appropriate.

 The first and most important observation was that both additives enabled resin to be injected on average at 10°F lower temperature than previously. In addition to exhibiting good flow at lower temperature, crystalinity was also excellent, enabling the cooling cycle of the injection process to be reduced on average 12.5%. These factors contributed to an overall cycle time reduction which correlated to a 4-7% increase in the number of parts produced.

XTEND® 1050 is new semi-permanent mold release specifically designed to resist hazing and loss of gloss which often occur in high volume FRP production and with many of the newer low VOC gel coats. XTEND 1050 is a quick flashing solvent formulation that simply wiped on the molds and allowed to dry, effortlessly providing a streak-free, high gloss mold surface. 

DICY cured epoxies are among the most tenacious in their bonding properties, prompting many in the industry to search for more effective ways to release DICY epoxy, resins, compounds, prepregs and laminates. Now AXEL offers two new internal mold releases: INT-1323 for accelerated DICY and INT-1329, for non-accelerated cures.
