WELD-ON 16
ACRYLIC PLASTIC CEMENT
SUBSTRATE RECOMMENDATIONS
WELD-ON 16 is especially formulated to bond acrylic plastic. It can also be used for bonding styrene,
butyrate, PVC and polycarbonate, as well as other plastics and porous surfaces.
BONDING RECOMMENDATIONS
WELD-ON 16 is recommended as an excellent general purpose, high strength acrylic cement. It is especially
useful where fast cure and high strength are desired for applications such as large housings, signs, plastic
letters, industrial fabrications, display items, lenses and models.
GENERAL DESCRIPTION
WELD-ON 16 is a very high strength, clear, medium bodied, fast curing, bodied solvent-type acrylic cement.
Applied to cast, molded or extruded acrylics, it will effect initial bonds within minutes and form strong joints
within hours.This product may be thinned with WELD-ON 3 by approximately 10%. Initial bond forms very
quickly so some parts may be handled within a few minutes of application. Bond strength continues to
develop very rapidly reaching a substantial level within hours. Joints are water and weather resistant and will
generally have similar physical and chemical properties to acrylic plastic.
BOND STRENGTH DATA
The following strength data was obtained with compressive shear loading at 0.05鈥?/min.The materials tested
were 1 4鈥? acrylic lap joints of 1 sq. in. bonding area.

DIRECTIONS FOR USE
Parts to be joined should be clean and fit without forcing.
鈥?
Apply WELD-ON 16 to one or both surfaces with brush, polyethylene squeeze bottle or gun.
鈥?
If cement is applied to one surface, bring the two surfaces in gentle contact for several seconds to
鈥?
allow the dry surfaces to be softened.
Assemble with firm pressure while parts are still wet.
鈥?
Hold or clamp assembled parts firmly until initial set. Joint strength will increase greatly in 24 hours.
鈥?
Thereafter, strength will continue to increase gradually for some weeks.
SHELF LIFE
Two years expectancy in tightly sealed containers. Stability of the product is limited by the permanence of
the container and the evaporation of the solvent when container is open. Evaporation of solvent will cause
the cement to thicken and reduce the effectiveness of the cement.

SAFETY AND ENVIRONMENTAL PRECAUTIONS
WELD-ON 16 is a flammable, fast evaporating solvent cement and is considered a hazardous material. In
conformance with the Federal Hazardous Substances Labeling Act, the following hazards and precautions
are given. Purchasers who may repackage this product must also conform to all local, state and federal
labeling, safety and other regulations.
DANGER - EXTREMELY FLAMMABLE - VAPOR HARMFUL - MAY BE
HARMFUL IF SWALLOWED - MAY IRRITATE SKIN OR EYES
Keep out of reach of children. Do not take internally. Keep away from heat, spark, open flame and other
sources of ignition. Contact with hot surfaces may produce toxic effects. Keep container closed when not in
use. Store in the shade below 80掳F. Use only in well ventilated area. Avoid breathing of vapors.
Atmospheric levels should be maintained below established exposure limits. See Section II and VIII of the
Material Safety Data Sheet. If airborne concentrations exceed those limits, use a supplied air respirator. Do
not use a chemical cartridge respirator. For emergency and other conditions where short-term exposure
guidelines may be exceeded, use an approved positive pressure self-contained breathing apparatus
(SCBA). Do not smoke, eat or drink while working with 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. Contains Methyl Ethyl Ketone (78-93-
3), Methylene Chloride (75-09-2) and Methyl Methacrylate Monomer (80-62-6). Methylene Chloride is a
possible human cancer hazard based on test results with laboratory animals. Risk to your health depends
on level and duration of exposure, as well as individual sensitivity. Do not use this product for other than
intended use.
"Proposition 65 Warning": This product contains chemicals known to the State of California to cause cancer.
"Title III Section 313 Supplier Notification": This product contains toxic chemicals subject to the reporting
