Overview
SP-1045 is used in combination with halogen and zinc donors to produce butyl vulcanizates with outstanding resistance to high heat and compression set. Vulcanizates cured with SP-1045 are nonblooming, nonstaining, and ozone resistant.
In addition, the reactive methylol groups in SP-1045 can be used as functional sites for a variety of reactions, such as with rosin for the printing ink market.
