Application Equipment

Suggestions (continued)

Material Supply:

Pressure Pots

Adhesive and Activator: For best results, use stainless steel pressure pots. Non-

stainless pressure pots may be used if used with plastic liner and the dip tube and

fittings are changed to plastic or stainless steel.

Pumps

Adhesive: Use a 1 inch plastic bodied, double diaphragm pump with PTFE

diaphragms and ball checks. It is suggested that all diaphragm pumps are short

stroked by the manufacturer before use. Do not use piston type reciprocating pumps,

or diaphragm pumps smaller than 1 inch. When using diaphragm pumps the use of

a bag type fluid filter is recommended on the output of the pump. A filter such as

the Graco Model 12 part number 915-518 with a 300 micron filter bag part number

521-264 or equivalent is suggested.

Fluid regulators cannot be used with this adhesive. Fluid pressure is controlled by the

pump pressure.

Activator: A 1:1 or 2:1 pogo or piston type reciprocating pump is suggested. All

pump parts in contact with activator must be plastic or stainless steel.

Diaphragm pumps and fluid regulators can be used (stainless steel or plastic on all

wetted components).

Hoses

All fluid hoses should be nylon or polyethylene lined. Hose fittings should be

stainless steel or plastic.

Note: Do not use fluid lines that have previously been used with solvent whether

flammable or nonflammable.

Handling/Application

Information

is required that at least one of each pair of substrates to be bonded be porous or water

permeable.

Surface Preparation

Surfaces must be clean, dry and dust free.

Spray Mix Ratio of Activator to Adhesive

It is recommended that Fastbond contact adhesive 2000-NF be spray mixed with

spray activator #1 at a ratio of 15 parts adhesive to 1 part activator (by weight or

volume). When activated, slight adhesive transfer should occur when adhesive film is

touched immediately after spraying.

Application

Use a plural nozzle, external mix spray applicator to mix adhesive with activator to

achieve proper mix of Fastbond contact adhesive 2000-NF with spray activator #1.

(Refer to Application Equipment Suggestions above for additional information about

spray equipment.) Spray apply a uniform coat of mixed adhesive to both surfaces.

(See coverage section.) One coat should usually be sufficient for both surfaces. Be

sure to overlap the spray pattern slightly with each pass of the spray applicator to

ensure complete activation of adhesive and uniform coverage.

A uniform dull film indicates sufficient mixture of Fastbond contact adhesive

2000-NF with spray activator #1.
