International Coatings 3804 PF Low Cure Additive is a phthalate-free plastisol ink additive designed to lower the curing or fusion temperature of most plastisol-based inks to below 300°F (149°C). It is especially useful when printing garments and materials that are sensitive to higher curing temperatures.
3804 Low Cure Additive can be used when printing on 100% cotton, poly/cotton blends, and 100% polyester. It is also suited for temperature- and color-sensitive substrates such as polyester garments and non-woven polypropylene bags.
The recommended addition is 5% to 6% by weight. The additive should be thoroughly dispersed into the plastisol ink to achieve optimum performance. Because plastisol ink formulations can respond differently when modified, testing the combined ink and additive before beginning production is strongly recommended.
In addition to lowering curing temperatures, 3804 can reduce flash cure times for most plastisol-based inks. When used with International Coatings All-Pro 900 Series inks for non-woven polypropylene bags, adding up to 6% can lower the cure temperature to 250°F.
Add 3804 Low Cure Additive to your screen printing inks when lower-temperature curing is needed, and explore more plastisol ink modifiers in our plastisol additives and reducers selection.
Product Bulletin
*Due to the performance difference in inks that 3804 Low Cure Additive may be added to, it is strongly recommended that prior testing be completed before beginning production to help ensure proper performance of the combined products.
