AQUAPOL® PI-13000-31 Prepolymer is an aliphatic urethane, end-capped prepolymer con- taining un-reacted isophorone diisocyanate (IPDI). Aquapol PI-13000-31 prepolymer will gel up to five times its weight of water and can be used to form stable gels with water. In contrast, concentrations of Aquapol PI-13000-31 prepolymer above 50% will result in closed cell foam rather than a gel. Gels will lose water to the atmosphere and should be protected with an impermeable membrane. The speed of reaction can be increased or decreased by using warm or cold water respectively and by the concentration of the amine catalyst. Using cold water will reduce any tendency toward frothiness.
