CASCOPHEN® ADHESIVE SYSTEM G-1131
A Room-Temperature Setting and Durable Resin Adhesive
Cascophen® Adhesive System G-1131 is a two component resorcinol-formaldehyde resin adhesive, capable of
curing at room temperature and providing strong, water-proof bonds of utmost durability. Cascophen Adhesive
System G-1131 is especially effective as an assembly woodworking glue where strength and resistance against
water, weathering, and dampness are required. These features are advantageous for general marine and aircraft use
and other exterior service applications.
Essentially neutral and inert, and possessing resistance to deterioration or disintegration on aging, Cascophen
Adhesive System G-1131 will provide strong bonds between woods, treated woods, many plastics, natural and
synthetic rubbers, primed metals, and porous materials such as paper, leather, textiles, fiber boards and asbestos
boards.
The cured glue line is completely resistant to fresh or salt water, most acids and organic solvents, and lubricating oils
and greases. However, alkaline solutions will act adversely on the glue line. The cured adhesive is thermoset so
elevated temperatures do not effect the bond; conversely, no loss in bond strength is encountered at temperatures
as low as -40ºF.
Cascophen Adhesive System G-1131 can be used advantageously in assemblies, such as laminated boat keels,
arches, and trusses, or where it would not be economical or feasible to use heat for curing because of the size or
shape or the number of glued assemblies being produced and where utmost durability with room temperature curing
is desired.
As required by the Toxic Substance Control Act (TSCA) Cascophen® Adhesive System G-1131 is listed in the
Chemical Substance Inventory. The CAS registry numbers for G-1131-A (resorcinol-formaldehyde polymer) and G1131-B (paraformaldehyde) are (24969-11-7) and (30525-89-4).

Storage Conditions
The liquid resin G-1131-A, should be stored between 32ºF – 90°F for 12 months. Frozen resin need only to be
thawed and
stirred well before using. Containers should be tightly closed to prevent solvent loss. Resins thickened through loss
of solvents may be thinned with denatured ethyl alcohol or water, or both, as required.
The hardener G-1131-B should be stored at temperatures below 80ºF. and kept dry. Continued exposure to higher
temperatures will decrease the reactivity. The oldest inventory should be used first.
Mixing Instructions

The working life of the adhesive is extremely sensitive to traces of acids or alkalies, so all mixing and spreading
equipment should be kept clean.
When the adhesive becomes too thick to spread, all the containers and spreading equipment should be immediately
emptied and cleaned by the use of scrubbing brushes and cool or warm water.
Wood Bonding
Preparation of Stock to be Bonded
The wood to be joined should be of the correct moisture content and should be machined so as to provide smooth,
clean and well-fitting surfaces. For best results, final surfacing should take place within the 24 hours preceding
gluing.
Moisture content of wood is most important and should be from 8-16%, preferably within the 10-12% range.
The temperature of the wood should be 70ºF., or higher.
Spreading
Cascophen® Adhesive System G-1131 may be applied by a resilient rubber roll mechanical resin glue spreader,
paint roller, or hand spread with a stiff bristled brush.
The joints may be double or single spread. In double spreading, the glue is applied to both surfaces of the joint, the
total amount of adhesive used being evenly divided between the two surfaces. Double spreading is recommended
for dense species and where the time required for assembly approaches the maximum permissible.

Recommended Spreads in Pounds
Per 1,000 SQ. FT. Single Glue Line

Assembly Time
The assembly period is the time elapsing between spreading a joint and applying pressure. “Open Assembly” is the
time between spreading and assembling the spread surfaces, while “Closed Assembly” is the time the spread
surfaces are in intimate contact before pressure is applied.
It is generally desirable to permit the adhesive to penetrate into the wood for 15-45 minutes (when at room
temperature) before applying pressure. For certain dense woods and other non-porous material, it is advisable to
allow part of the solvent to evaporate by providing a short open assembly time.
TABLE III
RECOMMENDED ASSEMBLY TIMES
Temperature of Maximum Permissible Open Maximum Permissible Closed
Room/Wood/Glue Assembly (minutes) Assembly (minutes)
70°F. 10 60
80°F. 5 45
90°F 1 30
100°F. 0 15
The times in this table are based on using either “open” or “closed” assembly, not both. When a combination of
these two assemblies is desired, the maximum assembly times can be proportioned from the table. For example, if
one-third of the maximum “open” assembly time is used, then only two-thirds of the maximum “closed” assembly
time can be employed.
Curing Conditions
(a) Pressure – In general, sufficient pressure to reduce the glue line to a thickness of 0.002-0.007” is
required. Thicker glue lines will result in an inferior bond. Pressures of 25-250 psi are generally used. In
thick assemblies, slight excess pressure is desirable to compensate for shrinkage.
(b) Temperature – Cascophen® Adhesive System G-1131 is adaptable to accelerated curing at
intermediate temperatures, as well as room temperature. Curing temperatures below 70ºF. should not
be used.

For curved stock the above times should be doubled.
When intermediate temperatures are used, the cure is speeded and penetration is improved. Table V is given as a
guide for minimum safe clamping times at various glue line (not press) temperatures.
A complete cure does not take place for about 6 days at room temperature, so joints should not be tested for final
strength or durability until after that time.
Stock may frequently be machined with safety immediately after releasing from the clamps, though it is best to defer
this for about 12 hours after removal of pressure. When intermediate temperature curing, i.e., above 100ºF., is used,
a complete cure is attained quickly and machining may take place immediately after pressing.

Bonding of Other Materials
Cascophen Adhesive System G-1131 will provide strong durable bonds to a large variety of materials, other than
wood. The following are illustrations:
A. Resin impregnated wood, molded and laminated phenolic plasticsand many other plastics such as ureas, the
cellulose plastics (except cellulose nitrate), nylon, methacrylates, polyvinyl alcohol, polyvinyl acetate and
foamed polystyrene, (not polyvinyl chlorides, Saran, Polystyrene, polyrethylene nor Teflon).
Surfaces should be lightly sanded. If sanding is not feasible, the surfaces should be cleaned with a solvent.
Note: When gluing together two non-porous materials, both surfaces should be spread and a ten minute
open assembly should be used. In some cases it is advisable to precoat the surfaces with a dilute solution of
Cascophen® Adhesive System G-1131 (such as 100 parts by weight of mixed adhesive plus 15 parts
denatured alcohol). This priming coat should be allowed to thoroughly dry before spreading with the regular
mix.
B. Natural Rubber, Styrene-Butadiene Rubber, Buna N, Neoprene, Thiokol and reclaimed rubber.
Best results are obtained if the surfaces are cyclized by pretreatment with concentrated sulphuric acid prior to
spreading. This treatment involves a five minute contact of the bonding surface with the acid followed
immediately by a thorough rinse with cold water and drying. Neoprene requires a more severe cyclizing
treatment with concentrated nitric acid.
C. Porous materials such as paper, leather, textiles, or fibers, plastic foam, plaster, cement fiber boards such as
“Masonite” or “Celotex,” asbestos and asbestos-cement boards.
Bonding Of Treated Wood
Woods treated with preservatives can be bonded with Cascophen Adhesives. For recommendations on specific
treatments and bonding conditions, contact Momentive Specialty Chemicals Inc.
Precautions
The proper use of Cascophen Adhesive System G-1131 should not create hazardous worker exposures, however,
each use location will require specific hazard potential analysis – see Material Safety Data Sheets describing the
individual components of this adhesive system.
In every case, high standards of cleanliness should be maintained to minimize the possibility of dermatitis. The use of proper
protective clothing and frequent washing is recommended.
