MoldTru™ LPT-68000 Tooling Resin For smoother, lower cost molds in less time MoldTru™ LPT-68000 low-profile tooling resin sharpens the competitive edge of polymer composites by providing a smoother tooling surface and saving moldmakers money and time. The tooling resin is for Open Molding, Resin Transfer Molding and Resin Infusion operations that can benefit from improved quality and higher profits. New Surface Quality Standard Researchers drew upon AOC expertise in automotive Class A resins to engineer a special additive technology that gives MoldTru LPT-68000 resin a near-zero shrink...

MoldTru™ LPT-68000 Tooling Resin For smoother, lower cost molds in less time Lower Tooling Costs To prevent surface distortion from high exotherm, conventional tooling resin requires individual laminates of thicker molds to cure overnight before adding subsequent layers. In contrast, MoldTru LPT-68000 exotherm is low enough to allow up to five layers of tooling laminate to be built simultaneously without causing surface distortion. Therefore, labor costs are lowered and the integrity of the master model is not threatened when the strictly-conforming production tool is pulled. Building A...

Guidelines for Building Open/Closed Mold Tools Consult with the AOC Technical Support Team for recommendations on which tool building materials best meet the performance requirements for your application. A full release agent system needs to be applied to the master model to prepare the surface for lamination. Once the release system is applied to the master, AOC suggests the use of a high temperature barrier to protect the surface of the mold. The barrier is the combined construction of a gel coat layer and barrier / skin coat layer. The ideal thickness of the temperature barrier (gel coat...

Guidelines for Building Open/Closed Mold Tools C. • Application of the first bulk layer BULK LAMINATE CONSTRUCTION If the resin is to be filled, AOC recommends only aluminum trihydrate (ATH, 10-19 microns) as it provides additional thixotropy properties to the mix and imparts the best profile character- istics. Other fillers, such as calcium carbonate, will not provide good profile characteristics and often increases viscosity too much. • If ATH is to be used, AOC recommends 40 parts for every 100 parts resin. • Step One: Apply a very thin, non-reinforced layer of resin to “wet” the part. •...

AOC in Composite Tooling AOC extends its leadership in composites materials with tooling resin technology that creates molds for Class A parts in less time and at lower cost. AOC tooling resin development is guided by the philosophy that the aesthetics and performance of a composite part can be no better than the mold that shapes it. AOC knows technology, lives quality and delivers service better than any other supplier. To discover more about AOC’s tooling expertise, e-mail sales@aoc-resins.com or go to www.aoc-resins.com.
