SCIGRIP IPS Weld-On #16 - Low VOC Acrylic Plastic Cement

General Description

Weld-On 16 is a very high strength, clear, medium bodied, fast curing, solvent-type acrylic cement. Applied to cast, molded or extruded acrylics, it will affect initial bonds very quickly so some parts may be handled within a few minutes. Bond strength continues to develop very rapidly reaching a substantial level and forming 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. Joints are water and weather resistant and will generally have similar physical and chemical properties to acrylic plastic.

Substrate Recommendations

Weld-On 16 is especially formulated to bond acrylic (poly-methyl methacrylate) plastic. It can also be used for bonding styrene, butyrate, PVC, ABS 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.

Additional Information

This product must be shipped via a ground service.

Technical Data Sheet (TDS)

Directions for Use

• Parts to be joined should be clean and fit without forcing.
• Apply Weld-On 16 to one or both surfaces with brush, polyethylene squeeze bottle or gun.
• If cement is applied to one surface, bring the two surfaces in gentle contact for several seconds to allow the dry surfaces to be softened.
• Assemble with firm pressure while parts are still wet.
• Hold or clamp assembled parts firmly until initial set. Joint strength will increase greatly in 24 hours. Thereafter, strength will continue to increase gradually for some weeks.

Shelf Life

Two years in tightly sealed containers. The date code of manufacture is stamped on the bottom of the container. Stability of the product is limited by the evaporation of the solvent when the container is opened. Evaporation of solvent will cause the cement to thicken and reduce its effectiveness. Adding of thinners to change viscosity is not recommended and may significantly change the properties of the cement.

WARNING! FLAMMABLE. VAPOR HARMFUL. MAY BE HARMFUL IF SWALLOWED. MAY IRRITATE SKIN OR EYES.

Keep out of the 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 away from direct sunlight below 80º F (27º C). Use only in adequate ventilation. Avoid breathing of vapors. Atmospheric levels should be maintained below established exposure limit values. See Sections II and VIII of Material Safety Data Sheet. If airborne concentrations exceed these limits, use a supplied air respirator. Do not use a chemical cartridge respirator. For emergencies and other conditions where short-term exposure may be exceeded, use an approved positive pressure self-contained breathing apparatus. In confined areas, use a positive pressure self-contained breathing apparatus (SCBA). 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, safety goggles, and impervious apron should be used. Carefully read Material Safety Data Sheet and follow all precautions.
