ADDSiL™ 2004 is a hydroxymethyl-terminated reactive silicone additive with much higher reactivity than conventional Si-OH silicones. Reacting with isocyanates, it integrates silicone segments into polyurethane/amino crosslinked systems, boosting low-temperature flexibility, water resistance, surface slip and anti-tear performance, and forms a permanent low-surface-energy layer on coatings.
