Primer: solventless epoxy primer, thickness: 60 × 65 μm; first intermediate coating: M 10 epoxy resin, thickness: 90 × 110 μm; second intermediate coating: polyurea, thickness 50 × 55 μm. Top coat: polyurea, thickness: 50 × 55 μm

Influence of additives, pigments and fillers on physical and mechanical properties and weatherability

The material from which weather strips for automobiles are made should have sufficient mechanical properties such as good toughness and abrasion resistance. Excellent weather resistance is very important and they should be resistant to washing and antifreeze. Furthermore, good surface quality is essential in places where the weather is sealed. In general, suitable tri monomers contain two sets of double bonds with different reactivities. It is desirable to copolymerize with the remaining EPM in the polymer chain; other sulfur vulcanizable materials with higher reactivity form a three-dimensional crosslinked structure. ENB is currently the most common and effective triplet

Effective membranes must have a number of mechanical properties such as permeability, porosity, pore size distribution, specific surface area, mechanical design and strength, electrical resistance, ionic conductivity, and chemical compatibility with electrolytes . At the time of use, the separator must have good acid resistance and oxidation resistance. The area of ​​the spacer must be slightly larger than the area of ​​the substrate to prevent material shorts between the substrates. The separator must be stable over the operating temperature range of the battery

Preheating and intermediate layer temperature control are recommended for optimum mechanical properties, crack resistance and hardness control. This is particularly important for multiple welds and heavy plates. Working conditions, current specifications, upper limits, alloy levels and other considerations may also require preheating and interlayer temperature control. Note: Lincoln Electric strongly recommends the use of welded parts for acid gas, sulfur-containing crude oil and other important service applications.
