Structural Adhesive 2 Part 25ml

DESCRIPTION:

Chemtools® Rapidstick™ 8-300 Methacrylate Structural Adhesive is a two-component, 100% reactive toughened adhesive with excellent impact, peel, and shear resistance in a convenient 1:1 mix ratio. Its non-sagging and thixotropic formulation is specifically designed for bonding a wide variety of metals, thermoplastics, thermosets, and composite assemblies. 8-300 fills gaps up to 9.5mm and is room temperature cured with a short open time. It is typically used for automotive components, marine assemblies, sporting goods, electronics enclosures, electrical appliances, furniture, plastic fabrications, metal fabrications, and signs.

Recommended bonding surfaces include, but are not limited to:

• Acrylic 
• PVC 
• Polycarbonate 
• Fiberglass 
• PBT 
• PPO
• ABS 
• FRT 
• Polyurethane 
• Epoxy 
• Wood 
• RIM
• Nylon 
• FRP 
• Polyesters 
• Gelcoats 
• Styrene 
• Aluminium
• CRS 
• Stainless Steel 
• Galvanized Steel

ADVICE ABOUT DISPENSING EQUIPMENT:

Care must be taken to ensure compatibility between the adhesive components and the materials in the equipment that they contact. All wetted metal components should be constructed of stainless steel or aluminum, or have a sufficient thickness of chemically resistant material that prevents contact between the adhesive components and the base metal. Contact with copper, zinc, brass, or other alloys containing these materials must be strictly prevented. All non-metallic seals and gaskets should be fabricated from Teflon® or UHMW polyethylene-based materials.

APPLICATION:

All surfaces must be clean and dry, and free of dust and grease. Best results will be achieved with surfaces that have been lightly abraded immediately prior to bonding.
Always dispense a quantity of adhesive at start-up to ensure the adhesive exiting the tip of the mixer is a uniform color, without streaks. If previously opened or aged material is being used, allow the purged material to cure to confirm quality before proceeding.
Carefully dispense a sufficient quantity of adhesive onto the substrate to ensure that the bond gap will be filled when the parts are joined. Allow for squeeze-out at the edges of the bond to ensure coverage.
Carefully secure or clamp parts to prevent joint movement while the adhesive sets. Do not apply excessive pressure that can cause excessively thin gaps and starve the bond line.
Test the curing adhesive at the edges for fingernail hardness before removing any clamps or fixtures.

CURING:

Working time is the approximate time after mixing components A and B that the adhesive remains fluid and bondable.
Fixture time is the approximate time after mixing components A and B required for the adhesive to develop sufficient strength to allow careful movement, unclamping, or demolding of assembled parts. Parts can generally be put into service when 80 percent of full strength is developed.
The time to achieve 80% cure is approximately 2-3 times that required for fixturing.
Note: The chemical curing reaction that occurs when components A and B are mixed generates heat. The amount of heat generated is controlled by the mass and thickness of the mixed product. Large masses over 12.7mm thick can develop heat over +121°C and can generate harmful, flammable vapors. Large curing masses should be carefully moved to a well-ventilated area where the chance of personal contact is minimised.

CLEAN-UP PROCEDURE:

Adhesive components and mixed adhesive should be removed from mixing and application equipment with a suitable industrial solvent or cleaner before the mixed adhesive cures. Once cured, soaking in a strong solvent or paint remover will be required to soften the adhesive for removal

SHELF LIFE:

12 months from the date of manufacture per the following conditions: Store continuously between 13°C and 23°C. Long-term exposure above 23°C will reduce the shelf life of these materials. Prolonged exposure of activators, including cartridges that contain activators, above 37°C quickly diminishes the product’s reactivity and should be avoided. Shelf life can be extended by refrigeration (8°C - 12°C). Do not freeze.

FIRST AID AND SAFETY PRECAUTIONS:

Always refer to the Safety Data Sheet/s before use. Use proper Personal Protection Equipment. Do not get in the eyes, on the skin, or clothing. Use with adequate ventilation. Avoid breathing fumes. Keep away from heat, sparks, open flames, and hot surfaces. This product may produce adverse health conditions, ranging from minor skin irritation to serious systemic effects. It should not be used, stored, or transported until the handling precautions and recommendations as stated in the Safety Data Sheet/s for this product have been fully understood by all persons who will work with the material.

STORAGE AND TRANSPORT:

Refer to Safety Data Sheet/s for recommendations. As a general precaution, keep containers tightly closed, protect them from sunlight, and do not expose them to temperatures exceeding 50°C. Store in a cool, dry place at room temperature (5 – 40°C). Do not return any unused material to its original container. Containers should be secured and stored upright during transit.
