  Characteristic: A-1  there have strong catalytic effect in water and isocyanate, can make polyhydric alcohol and the reaction of the isocyanate  balance.   A-1 adjusted to control the amount of bubbles rising and setting times, but it doesn't affect the tin catalyst operating range.   A-1 make the whole foam density and models to minimize compression.   - The catalyst is water-soluble, which is easy to measure.
