Procedure
Procedure Procedure 1 1 1, below.
Note
Evaporation of the reducer in the base
causes changes in the ratio. To prevent
evaporation, store the base in a closed
container.
Note
Some reducers have very little ability to
lubricate and many cause seals to dry out.
To prolong the seal life, be sure your pump
seals are compatible with the base’s reducer.
Contact your Graco representative for the
correct seals to use.
Procedure Procedure Procedure 1: 1: 1: Add Add Add Reducer Reducer Reducer to to to the the the
Base Base Base
When adding the reducer to the base before
proportioning with the Hydra–Cat system, determine
the ratio of the base/reducer mixture to the catalyst in
order to set the proper ratio.
Example:
The instructions on the can say “Mix 5 parts base to
1 part catalyst. Then reduce 3 parts of this mixture
to 1 part reducer.”
1. Add the parts parts parts of of of the the the base base base and and and catalyst catalyst catalyst to find the
parts parts parts mixture mixture mixture.
5 parts base
+ 1 parts catalyst

2. The next statement on the can says, “Reduce 3
parts of the mixture.” So divide the parts

mixture mixture mixture by 3 3 3 parts parts parts to to to reduce reduce reduce to find the parts parts parts
