Post cure finishes

Reduces frosting of permanent press blended fabrics MYKON 39 emulsion has been formulated to reduce the frosting effect on resin treated fabrics, especially those used in post cure finishing. In low concentrations it also helps to reduce "dusting" of the resin treated fabric. 

Its composition makes it particularly suitable for permanent-press finishing with zinc nitrate as catalyst for white and coloured goods. Compared with FIXAPRET CPN, it has the advantage that it does not change the shade of coloured goods or impair the whiteness of finished fabrics, not even under the severe curing conditions of the post-cure method when applied in combination with zinc nitrate. 

CNC POLYSOFT 35 is a non-ionic synthetic softener which can be used as a softener-lubricant on both pre-cure, post-cure and crease resistant finishes. 

Unique concentrated liquid self-finish. Used as the major softening component in pre-cure and post-cure permanent press processing. Provides full-bodied softness with surface slickness and luster. Effectively reduces "boardiness" on post-cured fabric. Improves fabric drape and surface touch after calendering wash/wear and pre-cure fabrics. 

Self-emulsiftable concentrate. 100% active softener which will not yellow up to 400F. Excellent resistance to scorching and particularly effective for both pre- and post-cure fabrics. Compatible with all resin and reactant systems or can be applied as a self-finish. 

Catalyst KR provides adequate cure to many thermosetting resins and reactants in both precure and post cure applications. It is a mild acting catalyst that provides minimal shade change with reactive and direct dyestuffs when used in permanent press finishes. It has excellent compatability with most commonly used finishing agents. 

Most paint systems can be used on RPs. For stoving finishes, the molding should be post-cured at 80C before the finish is applied airdrying finishes can usually be applied without post-curing. Most cellulose finishes are also suitable, but with these, it is particularly important to ensure that the resin has fully cured, to prevent the solvents attacking any uncured resin. 

The fundamental process of SLA is the solidification process of a liquid photopolymer, for example an epoxy resin. It is interspersed with suitable photoinitiators and exposed to ultraviolet (laser-) radiation, which initiates polymerization in those areas where the resin is heated by the laser beam according to the cross-sections. The beam deflection is realized by a scanner system consisting of two movable mirrors [102]. The curing is limited in the horizontal direction by the diameter of the laser beam and in the vertical direction by the optical penetration depth of the used resin. After completion of a layer the platform moves down according to the layer thickness and new resin is coated. After finishing the build process the model requires post-processing, in which the model is cleaned, the support removed and post-cured in a UV-hght chamber. 

The broad capabilities of dielectric thermal analysis make possible the definitive evaluation of many influences on measured dielectric properties and, therefore on the performance of finished products. These influences include crystallinity, cooling rates, annealing temperatures, and post-curing. Experiments to evaluate these factors are possible because of the ability of this technique to measure and control force and plate spacing (sample thickness). These data will help the scientist and engineer correlate end-use performance with such vital factors as chemical structure, molecular relaxations, and materials storage and processing conditions. 

Polymerization processes deliver the best surface finishes and the finest details. However, the supports must be removed in many processes, and the components are post-cured. 

Attention must be given to the volatility of the processing aid when selecting one for FKM fluorinated rubber. A good example is dioctyl phthalate (DOP) since the inclusion of 2.00-3.00 pphr of DOP will result in volatilization of it during demolding and oven post-cure. The finished parts will be undersized, hence the mold cavities must be cut to allow for the increased shrinkage. 

LSRs also have rapid cure cycles and, because post cure is not necessary, finished parts cost less than other thermoset technologies. 

These are water-soluble crystalline compounds sold as concentrated aqueous solutions. The methylol groups are highly reactive (118—122) and capable of being cured on the fabric by reaction with ammonia or amino compounds to form durable cross-linked finishes, probably having phosphine oxide stmctures after post-oxidizing. This finishing process, as developed by Albright Wilson, is known as the Proban process. 

Castable polyurethanes form a part of the overall polyurethane industry. They are normally prepared by the mixing of two to five ingredients and introduced into a mold. The materials are cured by the application of moderate heat, approximately 100°C, for 6 to 18 hours. The finished parts can be post-machined to obtain the right size and shape. 

For the production of San Daniele dry cured ham, these treatments could be defined as post-lethality processes to be applied to the finished product after debon-ing and before packaging under vacuum. The treatments showed a high level of repeatability and reproducibility. 

Amicon E1330LV/ Emerson Cuming Unfilled, no-flow fluxing underfill (reworkable) Not applicable Nickel-gold and OSP finishes Syringe, jet dispense, or stencil print Flip-chip, CSP, EGA modest post-reflow cure (offline) required.
