Clear One Component Solvent Based Bonding Agent for CPU

Clear One-Component Solvent-Based Bonding Agent for CPU

Product Description:
Thinkbond 42 is a Clear One-Component Solvent-Based Bonding Agent for Castable
Polyurethane Elastomers and Thermoplastic Polyurethane Elastomers (PU’s And TPU’s). Thinkbond 42 is a heavy metals free product.
BENEFITS:
Thinkbond 42 is a one coat bonding system for PU’s and TPU’S to all metals during the curing process.
Thinkbond 42 will also bond polyurethane elastomers to polyamides and other engineering thermoplastics, such as Hytrel® , polyester, PES, PPS and PPO, at 80ºC or above.
Thinkbond 42 has excellent environmental resistance to hot and cold water, fluids.
 
TYPICAL PHYSICAL PROPERTIES:
AppearanceClear to light Yellow liquid
Non-volatile solids (1h @ 105°C)21-25%
Specific gravity at 25°C0,88-0.94 g/cm3
Viscosity Brookfield at 25°C270 cps - #2 spindle @ 30 rpm.
Viscosity Ford Cup # 4 at 25°C80 s
DiluentsMEK/ PMA
Bonding Temperature Range80 to 150ºC
Shelf life1 year (closed can below 25ºC).
CHEMICAL COMPOSITION:
Resins and catalysts stabilized in ketone solvents.
METAL SURFACE PREPARATION:
Prepare the metal surface properly by removing completely oil, grease and dirt.
Blasting the surface with grit blasting steel so that the surface roughness is greater than 15 µm.
For aluminum surfaces we recommend the use of aluminum oxide as abrasive.
Clean again the substrate to remove dust from blasting residues.
If specified, the metal part can be phosphatized, galvanized, chromate conversion treated or KTL, before applying adhesive.
APPLYING Thinkbond:
Agitation: We recommend stir Thinkbond 42 before the application to avoid settle down.
Brushing: Application by brushing is normally undertaken without further dilution, but for
coating large areas, dilution with MEK (or the diluent blend shown below) improves flow and
speed of application.
Spraying: We recommend an HVLP gun using 1.5 Bar air-pressure and a nozzle size of 1 - 1.5mm. For this application we recommend diluting between 50 and 100% v/v.
Roller coating: Dilute to 35 - 45 seconds on a DIN 4 or Ford 4 cup at 25 C for most roller
Aapplication processes. Dilution with a high boiling solvent like MPA may be necessary to achieve the best finish and to reduce the skinning of the bonding agent in the applicator.
Drying: Dry the film between 10 and 30 minutes at room temperature. If it is necessary to reduce drying time, we recommend to use forced air for 5 minutes at 100ºC maximum. Do not use in this stage temperatures above 100ºC to avoid adhesive pre-cure.
After this process, follow to cure.
Thickness of application layer: The film obtained by applying Thinkbond 42 is colorless.
The layer thickness must be between 15 and 25 µm.
For severe environments or dynamic fatigue applications, use ≧25 microns. Under these conditions it is possible to achieve bonds with no edge-failure after 400 hour salt-spray tests Parts with Thinkbond 42 already applied can be stored for 30 days prior to cure.
STORAGE:
Keep container tightly closed during storage and always keep away from heat sources. Store in an environment below 10ºC increases the shelf life of the adhesive.
