Description
Making Fast Bonds of LSE Substrates Possible with No Surface Prep
Formulated for bonding polyolefins (low surface energy plastics) in assembly and fabrication applications
SCIGRIP 400LSE is a twocomponent (10:1), translucent,methyl methacrylate adhesive for bonding polyolefins with no surface preparation required. It bonds polypropylene, polyethylene and has the ability to cross-bond to metals like aluminium and stainless steel. Product is non sagging, and has short fixture times, making it an excellent choice for assembly and other fabrication or manufacturing uses.
DIRECTIONS FOR USE
SCIGRIP 400LSE is packaged in a twin-syringe cartridge that dispenses product in a 10:1 mix ratio. The cartridge must be inserted in the dispensing gun and the mixing tip attached prior to dispensing.
• Insert cartridge into dispensing gun. Open valve. Dispense a small amount of adhesive making sure that both components freely flow from the cartridge.
• Attach the mixing tip to the cartridge. Press the dispensinggun to dispense and discard approximately 1 – 2 inches
(2.5 – 5.0 cm) of the product, ensuring that the product is mixed properly in the mixing tip before use. If the mixing tip is left on the cartridge for a sufficient length of time without additional use, the adhesive may cure in the tip. If this
Substrate Recommendations
Weld-On 3 is formulated for cementing acrylic (poly-methyl methacrylate) plastic to itself. It is not recommended for cross-linked acrylic.
Bonding Recommendations
Weld-On 3 is used extensively in sign fabrication. Strong butt joints are made with flat sheets by using the soak method for such applications as cementing letters to acrylic panels. Butyrate trim-capping of acrylics is another highly recommended use for Weld-On 3. It is also widely used in the POP industry (e.g. display), and in the fabrication and bonding of plastic containers, housewares, bottles and many other applications using the capillary method.

Directions
Directions for Use
General: Surfaces to be joined must be clean, dry, and fit intimately without forcing. Apply cement with syringe, eyedropper or brush. Assemble while parts are still wet. If cement is applied to one surface, let the two surfaces be in gentle contact for a few seconds to allow the cement to soften the dry surfaces, then press parts together in firm contact. Initial bonds form very quickly. 65 – 80% of the ultimate bond strength will be obtained within 24 hours. Strength will continue to increase for several weeks.
Capillary Method: Parts are placed lightly together and cement is applied to the edge of the joint with syringe or eyedropper. By capillary action, the cement will flow a considerable distance, approximately 0.25 inch (0.64 cm), between two such surfaces. Allow a few seconds for the cement to soften the surfaces. Press parts firmly together.
Soak Method: Vertically dip surfaces until softened (approximately 2 to 5 minutes), then join pieces firmly together.
- In many cases, this cement dries too fast to apply by brush to the parts before they are joined.
- If crazing is a problem, we suggest you consider annealing before cementing.
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! 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.
