Catalyst Foam Basic Instructions

Condition part A and part B to at least 70 F before mixing. Vigorously mix
material in Part A until it homogenizes. Pour part B into Part A and mix for 30 -60 Seconds. Pour foam into place and let cure for at least 20-30 minutes before sanding and cutting. Please use rubber gloves while working with this product!

This foam will allow you to add support and rigidity to shafts without a significant weight increase.


Catalyst Stick Fill A/B is a two component, water blown polyurethane closed foam system. Catalyst Stick Fill A/B does not contain nor release ozone depleting chemicals during it's foam process.

Cured foams of Catalyst Stick Fill A/B demonstrates excellent weight to strength ratio. It provides high flexural strength, thermal stability and adds impact strength to structures supported with Catalyst Stick Fill A/B. Its low viscosity allows easy mixing and pourablity.

Application And Usage

Catalyst Stick Fill A/B can be used to provide internal pressure closed mold wet lay-up or as a light weight core material for molded products. Catalyst Stick Fill A/B's closed cell structure makes it an excellent choice for insulating in cryogenic applications. Catalyst Stick Fill A/B can also be used in acoustical design applications.

Pre-Mixing Notes: Condition Part A and B to at least 25 oC. Part A contains fillers thatneeds to be re-dispersed prior to adding Part B. Mix vigorously for about 2 minutes or until Part A is uniform in consistency. Add the correct amount of Part B and mix for approximately 30-45 seconds. Pour into place and let foam cure for 25 minutes before sanding or cutting.

"prepare tooling to be foam. Make sure that it is free of dirt grease and other surface contaminants. Solvent wipe or scuff with mild abrassive of possible. Wear the provide latex gloves before opening the containers."

"Open part 'a' and mix until uniform. Pour the entire contents of the part 'b' into the part 'a' container. Mix vigorously for approximately one minute and pour directly into the tooling. The material will begin to foam within 2 minutes."

"Let foam cure for 30 minutes before handling. Excess foam can easily be trimmed and sanded with a hack saw blade and medium coarse sand paper. Dispose containers and gloves properly. Do not reuse containers."
