The ultimate bonding agent for a problem-free application on many materials like silicones, teflon, latex, PET (Polyethylenterephtalate), PP (Polypropylene) and PE (Polyethylene) which have to be bonded securely, durably and quickly.
Application:
Apply TURBOBOND Primer Plus, covering both sides of the materials to be bonded with the brush located in the screw top. On porous materials apply 2 or 3 times. Leave to dry for approx. 20 seconds before applying the Adhesive to one side of the material. Join parts under pressure.
Due to different material compositions, the following values are a guide only.
Hardening times for: latex and silicone: a few seconds
PTFE: 2 hours
PE, PP: 2 to 8 hours
POM, PET, TPE: 3 hours.
In most cases, the final strength is reached within 8 hours. Consider that the tensile strength is many times higher than the shore strength to be reached.
Storage:
Keep out of reach of children.
Store in a dark place.
Non-aging.
Size:
Available in a 10ml bottle with brush cap.
Polyolefins are very difficult to bond as they are non-polar and non-porous, plus their high degree of chemical inertness to solvents generally limits the usefulness of solvent bonding as a viable assembly technique. One successful approach to adhesive bonding of these materials involves proper surface pre-treatment. Surface preparation and pre-treatment is necessary to bond well to polyolefins.
All surfaces to be bonded must first be thoroughly cleaned so as to assure the removal of all traces of oils, greases, dirt and any mold releases. Good degreasing agents include acetone and other ketones as well as selected alkyl acetates. Alcohols, petrol and paint thinners are less effective.
Mechanical roughening or abrasion is a second necessary process step for enhancing bond strength. A second degreasing step after abrasion should be considered to ensure the removal of loose particles.
Acid etching is also a very effective surface pretreatment method. Mostly used are sulfuric or chromic acid solutions. Etching must be followed by thorough water rinsing to remove any residual acid and then drying.
Exposure to an oxidising flame is another simple yet quite successful pretreatment method. A blue flame from an oxyacetylene or propane source is quickly passed over the plastic surface until it becomes glossy or shiny. After treatment, the plastic surfaces should be washed with water and detergent and then thoroughly dried. This pretreatment is most successful with parts comprised of thicker sections.
Electrical discharge methods create free radicals which form oxygenated functional groups for improving bonding to adhesives. Corona treatment is of particular value for facilitating bonding of thin films and foils.
Gas plasma treatments can be used for small complex geometric surfaces which are difficult to abrade or flame treat, but require strong bonds.
Specially formulated primers can also used as a pre-treatment procedure. Primers are used in conjunction with other adhesives such as epoxies and urethanes. Another primer-type system involves the use of instant adhesives or cyanoacrylates. Cyanoacrylates will bond to many polyolefinic substrates when used with a special primer.
Turbobond Primer Plus is to be used in conjunction with Turbobond Powerglue. It has been engineered to promote the bondability of polyolefinic surfaces, to effectively remove contaminates and increase the cure speed of Turbobond Powerglue. This system provides for high strength, fast setting bonds
Turbobond Primer Plus also increases the ability to bond other difficult materials as silicone, rubber and thermoplastics elastomers.
Turbobond Primer Plus can be used by simply applying it to the parts you wish to bond. Allow to evaporate for about 30 seconds and then bond parts with Turbobond Powerglue. For the best results bonding should take place within 60 minutes of priming. Keep the primed area free of contamination or handling. Turbobond Primer Plus will not effect the setting time of Turbobond Powerglue. Ultimate setting will be achieved within 24 hours.
