Weld-On 10 is a two-component, white, high strength adhesive. It cures by the reaction of base Resin A with Catalyst B.
Weld-On 10 is formulated for large PVC (Polyvinyl Chloride) pipe and fittings, but has been found to bond many other plastics and non plastics. Preliminary tests show good bond strength with PVC (vinyl) – rigid and flexible (with low plasticizer content), ABS, polycarbonate, styrene, acrylics, butyrate, hard rubber and possibly others not yet tested. It does not bond well to Neoprene or other synthetic rubber, Delrin, Celcon and a few other plastics.
Weld-On 10 is recommended for a variety of applications due to its high strength and versatility as a structural adhesive. It is used in the sign assembly industry for bonding a variety of plastics. It also has many uses in other fabrication industries that bond ABS, acrylic, polycarbonate, PVC and other plastic substrates.

Directions for Use
Preparation of Substrates: High gloss hard surfaces including glass, ceramics and thermoset polymerics such as Bakelite® benefit from sanding using a fine grit followed with a tack cloth. The surfaces to be bonded must be degreased, clean and dry for consistent surface adhesion using this product. When a degreasing agent (e.g. chlorinated solvents, MEK, acetone, or isopropyl alcohol) is required, confirm that the substrates will not be damaged during contact with the solvent.
Method (1): Weld-On 10 is packaged in pre-measured kits. When the entire package is to be used, all of Catalyst B may be mixed directly into base Resin A and used at once. The package ratio is 100 parts Resin A to 13 parts Catalyst B by weight, so smaller batches may be made by respecting the same ratio. Once mixed, pot life is about 30 minutes at 70ºF ( 21°C). Cure of an applied thin layer is about 4 hours at 70ºF (21°C). Higher strength is reached in 24 to 48 hours. Cure may be accelerated in some applications either by applying heat to the glue line, about 150ºF (66°C), or by using additional Catalyst B. Increasing the amount of the Catalyst B from 13% to 25% by weight will substantially decrease both cure time and pot life. This will however decrease the ultimate strength of the bond. If higher strength is more desirable than cure speed, the 100:13 ratio should be respected.
Method (2): A unique property of Weld-On 10 is its ability to cure by simple contact of Resin A with Catalyst B. This means that the user may apply a coat of Resin A to one substrate and a coat of Catalyst B to the other, then assemble the parts ensuring good contact of Resin A with Catalyst B throughout the glue line. Use of this method eliminates pot life limitations. Coat a film of Catalyst B on nonporous substrate. Resin A may be used more generously on the other substrate, porous or nonporous. Where a large gap is to be filled, apply Catalyst B to both surfaces before applying Resin A. For ABS or Styrene, after coating Catalyst B, allow it to dry for about 5 minutes before applying Resin A.
NOTE: Individual components, in particular Catalyst B, exhibit lesser adhesive properties than the mixed product. Where METHOD (2) is chosen, care must be taken to ensure that Catalyst B adheres sufficiently to the particular substrate being bonded. In general, METHOD (1) will provide faster cure and higher strength.
One year in tightly sealed containers stored in a cool 50 F – 80° F (10 C – 27° C) dry place. Storage near the ceiling in non air-conditioned warehouses is not recommended. Shelf life is reduced at higher temperatures and enhanced at lower temperatures. Keep away from sources of heat, open flame, sparks and sunlight. The date code of manufacture is stamped on the bottom of the container.

Keep out of reach of children. Do not take internally. Keep away from heat, spark, open flame and other sources of ignition. Keep container closed when not in use. Store away from direct sunlight between 50° F – 80° F (10° C – 27° C). Use only in adequate ventilation. Avoid breathing of vapors. Atmospheric levels should be maintained below established exposure limit values. See Section II of Material Safety Data Sheet. If airborne concentrations exceed those limits, use of a NIOSH-approved organic vapor cartridge respirator with full face-piece is recommended. The effectiveness of an air-purifying respirator is limited. Use it only for a single short-term exposure. For emergency and other conditions where short-term exposure guidelines may be exceeded, use an approved positive pressure self-contained breathing apparatus. Do not smoke, eat or drink while working with this product. Avoid contact with skin, eyes and clothing. May cause eye injury. Protective equipment such as gloves, goggles and impervious apron should be used. Carefully read Material Safety Data Sheet and follow all precautions.
