Plastisol Viscosity Adjustments
501 Curable Reducer: Excalibur's 501 PF Curable Reducer can be added to any Excalibur Phthalate-Free Plastisol ink to not only drop the viscosity but also help improve the flow of the ink and help the ink clean completely from the screen mesh. Even though it can be used in any quantity the following precautions should be taken when mixing 501PF Curable Reducer into Excalibur Plastisols.
502 Reducer Concentrate: is a concentrated product that in limited amounts greatly decreases the viscosity of the ink as well as increasing the flow characteristics making the ink clean completely from the screen. Limited amounts of 502PF Viscosity Reducer will make designs on light-colored shirts simulate the feel of a water-base print. As 502PF Viscosity Reducer is not a balanced product and can cause curing issues with any ink that it is added into, care should be taken and the following cautions explicitly followed when adding this product to any Excalibur plastisol ink!
1501 SportPro LB Curable Reducer: 1501PF Low-Bleed Curable Reducer can be used to adjust the viscosity of any Excalibur low-bleed ink without fear of diminishing the bleed resistance of the ink. Even though any amount of 1501PF can be added, when printing dark substrates, best results are obtained when adding no more than 3-5% by weight to the ink. Because plastisol inks are thixotropic in nature and can have a false body during storage, it is recommended to always stir ink prior to adding reducer. Excalibur inks that 1501PF are recommended to be used with are SportPro 1533PF and 1550PF Series, Defender 1596PF, 590PF Sabre White, 596PF Miracle White, TKO White and TKO Bright White.
EXE Thickener: Use Excalibur EXE Thickener when it is necessary to increase the viscosity of plastisol inks. For best results EXE Thickener should be added in increments of 1% by weight until desired viscosity is achieved. EXE Thickener produces excellent results when used with Excalibur 550PF or 500PF Series and HD-1 High Density Additive to increase viscosity for high-density printing applications. Because EXE Thickener has only been tested and results evaluated when mixed with Excalibur plastisol inks. Lancer Group International cannot guarantee the results if this product is used with a competitive brand of plastisol ink.
Care should be taken when adding any modifiers such as reducers, thickeners, low bleed additives etc. to any ink as it can affect film strength, opacity, printability and coverage. Always test finished prints for curing, adhesion and desired look prior to beginning full production runs. Lancer Group International cannot guarantee the results or back claims that the mixed ink will test phthalate-free if any ink other than an ink manufactured by Lancer Group International is modified. Test results by a third-party laboratory verifying all components used to produce this additive are phthalate-free and lead-free are available upon request.
