There are 4 main things to consider:

1. Viscosity

2. Speed

3. What is to be bonded (substrate

4. Service conditions / Environment


POWERBOND Cyanoacrylates exist in a wide range of viscosities, from wicking grades (5Cps, like water), through to gel. The viscosity chosen will depend on many factors including surface smoothness, fit between parts, gap filling and application method.

CURE SPEED vs BOND GAP
Speed of bonding should be chosen to suit the process. For automatic assembly and high speed processes, a fast bonding time will reduce inventory and the need for fixturing. For manual operations a slightly longer positioning time might be desirable.
POWERBOND cyanoacrylates give best results on close fitting parts, for rapid cure speeds apply the adhesive in a thin line.

CURE SPEEDS vs ACTIVATORS
POWERBOND Activators will increase the cure speed of the higher viscosity adhesives or in applications requiring "fillet" bonding but activators can reduce the final bond strength by up to 30%

CURE SPEED vs ENVIRONMENTAL CONDITIONS
Low Humidity and Low Temperature slow down the cure speed.

PRIMERS
POWERBOND LA77 Primer is required to successfully bond Polyethylene, Polypropylene and PTFE. POWERBOND primers for cyanoacrylate adhesives enhance cure speeds on porous and acidic surfaces and permit bonding on substrates such as polyethylene, polypropylene and even Teflon®. Used in pre-assembly applications,

DeBONDER
POWERBOND D68 DeBONDER Cured Cyanoacrylate may be removed from most substrates and parts disassembled with POWERBOND D68, apply to locks to slow down or prevent adhesive cure through vandalism. Cyanoacrylates cannot be removed successfully from fabrics.

QUALITY CONTROL & CERTIFICATIONS POWERBOND Cyanoacrylate adhesives are manufactured to meet ISO 9001 – 2000 and QS9000 quality standards. Many of our medical products are USP Class VI approved, and we possess military approvals including MIL spec -A-46050C as well as numerous original equipment manufacturers approvals.
