High Rise Foaming Agent: Rounding out our Foaming Agents is our High Rise Foaming Agent, having the greatest foaming action compatible with natural latex foam. It easily produces super high volume latex foam and can also be used in hot summer weather. If you absolutely have to run foam in hot environments, this will give you more work time. This will help if you've cut way back on the gelling agent and your foam is still going off too fast.
