- Mixing and Application
All surfaces must be clean, dry, dust and grease free. Best result will be achieved with surfaces that have been lightly abraded immediately prior to bonding. Always dispense a quantity of adhesive at start-up to assure that the adhesive exiting the tip of the mixer is the proper color and is uniform, without streaks. If previously opened or aged material is being used, allow the purged material to cure to assure quality before proceeding. Carefully dispense a sufficient quantity of adhesive on the substrate to assure that the bond gap will be completely filled when the parts are joined. Allow for squeeze-out at the edges of the bond to assure filling. 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 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 in service when 80 percent of full strength is developed. The time to achieve 80% cure is approximately 2-3 times that required for fixturing.
- Clean Up
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 the adhesive cures, soaking in a strong solvent or paint remover will be required to soften the adhesive for removal.

Technical Details & Test Data
- Lap Shear Strength Data
Turbo-Bond 300 formulated to bond wide variety of substrates. Lap shear strength data according to ASTM D 1002 reported for the most common substrates:
Substrates Shear Strength & Failure Mode Stainless Steel / Stainless Steel 3,480 psi – Cohesive Failure Aluminum / Aluminum 3,190 psi – Cohesive Failure ABS / ABS 1,500 psi – Substrate Failure FRP / FRP 1,700 psi – Fiber Tear Aluminum / ABS 2,200 psi – Substrate Failure
Result : Lap shear strength figures are lower for the plastic surfaces due to substrate failure which means substrate is failing before the adhesive bond.- Cleavage Peel Data
Turbo-Bond 300 have the ability to withstand at high level of peel stresses. Following are the results of Cleavage Peel strength based on ASTM D 3807:
Stainless Steel / Stainless Steel
Initial Strength – 20 pli
Average Strength – 18 pli
Result : The above results shows the strength required for the joint to begin to peel and joint resistant with average strength.- Chemical Resistance Data
The chemical resistance of 7300 was studied by bonding the Aluminum/Aluminum as per specification and cured for 7 days at 25°C then kept immersed in the media listed here and tested for lap shear strength.

Turbo-Bond 300 have excellent resistance to harsh environment conditions. The testing data is as follows:
Condition Lap Shear Strength & Mode of Failure
Initial 3,480 psi – Cohesive Failure
Environmental Cycle – 30 days 3,950 psi – Cohesive Failure
Lap Shear Strength ASTM D 1002 – Stainless Steel / Stainless Steel
Environmental Cycle = 8 hours at -30°C, 8 hours at 85°C, 8 hours at 30°C at 100% Relative HumidityResult : The lap shear strength has increased after environmental cycle. Turbo-Bond perform better under these conditions compare to the substrates bonded. Substrates may have less resistance to these conditions compare to adhesive.
Safety & Health
- Handling & Precautions
Adhesive component A contains methyl methacrylate monomer and always use in a well-ventilated area. Activator component B contains peroxide. Both materials must be stored in a cool place away from sources of heat and open flames or sparks. Keep containers closed when not in use. Prevent contact with skin and eyes. In case of skin contact, wash with soap and water. In case of eye contact, flush with water for 15 minutes and seek immediate medical attention. Harmful if swallowed. Keep out of reach of children.
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 1/2 inch thick can develop heat in excess of 250°F/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 minimized.
Storage & Handling
- Dispensing Equipment
Dispensing directly from disposable cartridges or meter-mix-dispensing equipment is strongly recommended. Both methods employ convenient static motionless mixer technology. Product supplied in pre-measured cartridges is dispensed from approved manual or pneumatic powered guns. When meter-mix dispense systems are used, care must be taken to assure 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.
- Storage & Shelf Life
Shelf life of adhesive (Part A) is 1 year from day of shipment from Palm Labs. Shelf life of activator (Part B), including cartridges that contain activators, is 9 months from day of shipment. Shelf life is based on continuous storage between 55°F and 75°F. Long term exposure above 75°F will reduce the shelf life of these materials. Prolonged exposure of activators, including cartridges which contain activators, above 100°F quickly diminishes the product’s reactivity and should be avoided. Shelf life can be extended by refrigeration (45°F - 55°F). These products should never be frozen.
