Description

This is a special activator specifically made for use with CA superglue! (CA not included)
USA Postage included in the price
!
Parson #3770 Primer
is specifically designed to help CA bond properly to "low surface energy" plastics such as: Polypropylene, Polyethylene, Silicone Rubber, PTFE, and thermoplastic polyolefin.
(It also works on other kinds of plastics as well)
This primer product works with all kinds of CA glue and is
specially formulated to help CA form a improved bond with plastic materials.
It can also be used with CA to bond Silicone rubber.
Without the primer, CA doesn't perform well with those kinds of plastics and rubbers.  The primer acts as a
surface cleaner
and
catalyst
to chemically promote adhesion.  If you have had problems with CA bonding to certain plastics and rubber, this product may be just
what you need.
Note
: The 4oz bottle does NOT come with a sprayer, its meant to refill smaller bottles. The 2oz bottle comes with a sprayer and the 1oz bottle comes with some "Q-tip" swabs.   CA glue is NOT included with this purchase, but any kind of CA adhesive will work with the primer. T
here are several CA glue products available in my ebay store.
PLEASE READ THE NOTES!
Instructions for Use
:
Any CA will work but I recommend using "Flex" CA (which I sell).  "Flex" is a special CA formulation works really well with plastics. If the plastic is very smooth or has a shiny finish, use a fine-grit sandpaper to "haze" it and improve the performance of the primer. The surfaces being bonded must fit very well together, as tightly as possible. (little or no gap).
Prepare difficult-to-glue surfaces first
.
The plastic surfaces must be completely clean of oil or mold-release residue. Use rubbing alcohol or use the primer itself as a cleaner - rub the surface well and let it dry completely.
Then
-
Apply the primer solution onto the two surfaces you will be gluing, and allow to completely dry - at least 3 minutes.
Finally
-
Apply the CA glue within 6 hours. Use the smallest amount of CA glue possible, then clamp or press the parts together
very
tightly
and hold for 20-30 seconds. The glue will be at "fixture strength" and the parts will be OK to handle - but the bond will not reach full strength until 24 hours have passed.  Allow the glue to fully cure for the best results.
Primer #3770 isn't necessary on materials that CA doesn't have any problem with. But use it whenever you are bonding plastics for the best results.
For items that are rough or do not have a close-fitting glue joint, use
thicker
CA or gel (which I sel
l).
Do
not
apply primer to parts of the plastic that you are not gluing. The primer will react with the plastic and can damage the finish.  Due to the nature of this product, it will even attack the sprayer and may eventually prevent the sprayer from working properly - but you can still use a Q-tip or swab.
This product will cause CA glue to cure relatively quickly.  Please note, unfortunately I cannot guarantee that this product will work for a particular purpose, since there are so
many
kinds of plastics. Do not combine this product with regular acetone-based CA accelerators. (Acetone will damage plastic.)  Primer #3770 will work with ALL kinds of CA.
Please note, this primer product and most kinds of CA are NOT foam-safe! Check first to be sure!
If you're working with foam, your CA glue must be foam safe too!   But, t
his primer works with
all
kinds of CA glue. There are videos on YouTube showing how Primer #3770 can work with bonding Silicone in particular. Google "Bonding Silicone Rubber" to see this product in action.
