Phenolics Require heat and pressure to cure bond Metal to metal, metal to wood, and metal to brake-liners Plastisols Modified PVC dispersion that requires heat to harden. Resilient and tough Polyurethanes Two part and fast curing. Form strong, resilient joints that are resistant to impact Glas...
The component’s physical dimensions impact on the ΔCTE that can tolerate itself. We have tested several products [13–17], with low modulus of elasticity, recommended for high power applications (Table 2). We have proved their capability to compensate the stress also at cryogenic temperatures...
there must be a reactive group “B” that it can react with. For two-component systems, A and B are in separate sides and mixed through a nozzle. For one-component systems, one of the components is activated using heat that allows the reaction to proceed. ...
Herein we report a self-adhesive conductive polymer that possesses low modulus (56.1-401.9 kPa), high stretchability (700%), high interfacial adhesion (lap-shear strength >1.2 MPa), and high conductivity (1-37 S/cm). The self-adhesive conductive polymer is fabricated by doping the poly...
Direct bondings of glass at room temperature are achieved by surface activation in plasma or in liquid phase. The processes applied in the first case are (1) argon atom fast beam53, (2) reactive ion etching banasdedN2onmaiclraobwoarvioeu54s, and (3) process RIE that iinnvoOl2veasnwd...
(such as metal stearates including zinc stearate, calcium stearate, and aluminum stearate). Use of such materials for the powder depends on whether the intended end use of the non-tacky resultant composition will tolerate such materials, which typically do not melt under certain typical heat ...
A large number of hardeners exist, allowing adhesive systems with a range of properties to be produced with a single adhesive. One-part adhesives need heat to activate the catalyst and initiate the cure. Anaerobic adhesives are unusual in that they are stable in the presence of air but once...
Due to component heat sensitivity, substrate flexibility, mismatched coefficients of thermal expansion, proposed legislative ban on lead, processing advantages and other design considerations, alternative approaches to component attach are needed. One approach that is gaining in importance is use of an ...
and be able to tolerate the presence of moisture without releasing. Pressure-sensitive adhesives generally comprise elastomers that are inherently tacky or include tackifying resins. Exemplary adhesives for use in the invention include rubber elastomers, acrylics, acrylates (e.g., cyanoacrylates), epox...
This need is particularly acute for high volume automated bonding operations, which can tolerate neither frequent periods of downtime for thawing nor the expense of discarding adhesives that quickly become ineffective. This need must be achieved without sacrificing good adhesion characteristics. DISCLOSURE...
