Dolphon® CB-1128-Tips for Spray-On
The data sheet for our Dolphon CB-1128
refers to it as a "Flexible Motor Compound." Of course, being
a member of our polybutadiene family of products, the final coat
is flexible, meaning it has the elasticity to absorb the impact of flying
particles present in mineral mining or paper mill environments. It also
resists cracking when subjected to thermal cycling. But we can also
extend that definition of flexible to its application methods. Not only
can the resin and reactor be mixed to form a thixotropic paste suitable
for brush-on applications, but CB-1128 can also be thinned with xylene
to allow it to be sprayed-on. Since this application method requires
the mixing of 3 components, we are periodically asked the best way to
mix the resin, reactor and solvent. In this case, the order of the mixing
- Mix the Part A (resin) and Part B (reactor) each separately and
- Prepare your unit according to the Data Sheet.
- Decide the amount of resin necessary for the job. Based upon a mix
ratio of 100 parts resin to 6 parts reactor by weight, weigh
the proper amount of reactor. (Of course since CB-1128 is sold in
conveniently pre-measured kits, this is already done, assuming you
will be using a whole kit.) Do not mix the resin and reactor at
- Add xylene to the resin, up to 20-40% xylene by weight to get the
desired spraying consistency. Mix the resin and solvent thoroughly.
- Add the pre-measured reactor to the resin-solvent mixture. Mix thoroughly
Mixing the xylene thoroughly with the resin prior to
adding reactor allows for an even, consistent coating, and prevents
the material from beginning to set up before the mixing is complete.
Please note that diluting the resin in this manner will extend the pot
life of the product.
We hope CB-1128's "flexibility" of application
will help you and your customers find many uses for this versatile product.
And remember, the DOLPH Resin spray gun is perfect for spraying CB-1128.
