Exterior product

Thus, the exterior product of an ordered pair of vectors a, b is a tensor... 

One differentiates between interior and exterior fireproofing. Interior produets are typieally less substantial, with lower densities and lower eost. Exterior produets have to withstand more extreme fire and other environmental conditions. Exterior products are also more likely to be attraetively tooled, whereas their interior eousins are usually merely sprayed in place. 

The sums are computed by first summing over all contacts for a given particle and then by summing over all particles (0 refers to the exterior product of the vectors). Note that a continuum stress field can be computed by appropriate coarse-graining strategies [30]. The pressure is then P = (u2 + i)l2 and the shear stress is T = (u2 - cti)/2 for the 2D case, where the are the eigenvalues of d. 

Premium and specialty plasticizers are used for special performance requirements such as resistance to migration, marring, volatility, and failure under low-temperature conditions. Some of these extmded shapes—especially gaskets—utilize chemical blowing agents to provide low-density, foamed shapes. Extmded straps for lawn chairs, as well as other exterior products, are typically formulated with GP plasticizers plus antioxidants, UV absorbers, and fungicides. 

The exterior form of MDF is used in special appHcations requiring durabiHty and resistance to water or weather exposure. Highway signs would be an example of this use of exterior MDF. It is an extremely expensive product and thus is used only for special appHcations requiring its special properties. Another example of use would be where a customer would be willing to pay the additional cost to use a composite which has the exceptional quaHties of MDF, but also has virtually no formaldehyde emissions. 

The manufacture of waferboard and OSB has many of the same process steps as particleboard, but adapted to the special needs of producing an exterior quaHty panel with large wafers or strands. This discussion focuses on OSB, because waferboard has been almost entirely replaced by OSB and most of the early waferboard mills have now been converted to production of OSB. The OSB process is outlined in Figure 8. 

Protective Coatings. The primary function of interior can coatings is to prevent interaction between the can and its contents. Exterior can coatings maybe used to provide protection against the environment, or as decoration to give product identity as well as protection. 

Sodium hydroxide, potassium hydroxide, or other caustic compounds are blended to make these types of removers. Polymer-type thickeners are added to increase the viscosity that allows the remover to be appHed with a bmsh, trowel, or spray. Some of these products use a paper or fabric covering to allow the remover finish mixture to be peeled away. The most common appHcation for this group of removers is the removal of architectural finishes from the interior and exterior of buildings. The long dwell time allows for many layers of finish to be removed with one thick appHcation of remover. 

Melamine or melamine—ureas are used in the manufacture of tmck and railroad flooring, laminated lumber, beams, exterior doors, marine plywood, toilet seats, and school furniture. The bonds in these products meet a variety of commercial, military, and federal specifications for exterior waterproof adhesives. 

New product introductions are generally heavily supported by the technical service function. Many customers using chemical feedstocks to produce multicomponent products for the consumer market require extensive on-line evaluations of new raw materials prior to their acceptance for use. An example of this would be the use of a new engineering polymer for the fabrication of exterior automobile stmctural panels. Full-scale fabrication of the part foUowed by a detailed study of parameters, such as impact strength, colorant behavior, paint receptivity, exterior photodurabiHty, mar resistance, and others, would be required prior to making a raw materials change of this nature.
