Detailed Product Description
Clear One-Component Solvent-Based Bonding Agent for CPUProduct 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:
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. Shanghai LoreChem Co., Ltd. was established in 2008. It is a
high-tech enterprise which is dedicated to serve releasing products
which involve semi-permanent release agent, anti-sticking, surface
lubrication and thermal reactive adhesive. Shanghai LoreChem has
been improving product quality for 15 years. The releasing products
are mainly applied in rubber, polyurethane and composite industry.
The brand of Lubekote for release agent and Thinkbond for adhesive
have been registered in China. Both of them are well known in the
industry. Shanghai Lorechem Co., Ltd. was established in 2008. It is a high-tech enterprise which is dedicated to serve releasing products which involve semi-permanent release agent, anti-sticking, surface lubrication and thermal reactive adhesive. |
