Resonac Chloroprene 115

Resonac Chloroprene 115 by Resonac (formerly Showa Denko) is a medium solid, carboxylated, non-ionic, aqueous dispersion of a low-gel copolymer of chloroprene and methacrylic acid stabilized with polyvinyl alcohol. It has good storage stability and broad tolerance to many materials destabilizing liquid dispersion. It offers hot bond strength and has a slow crystallization rate. <br> <ul style="padding-left: 40px;"><li>The pH decreases with time and the rate depends on temperature and air exposure that is indicative of structural changes in the polymer and alterations in the colloidal properties of the latex. </li><li>Resonac Chloroprene 115 is used in contact adhesives and sealants.</li></ul>

Resonac Chloroprene AF

Resonac Chloroprene AF by Resonac (formerly Showa Denko) is a carboxylated chloroprene copolymer. It has a slow crystallization strength and milling normally is required for optimum solution quality. It provides the rapid bond strength development and the greatest hot bond strength.<br> <ul style="padding-left: 40px;"><li>Excessive time and temperature of storage can cause a change in color and an increase in viscosity.</li> <li>It is primarily used in contact adhesives that require very high initial and ultimate bond strength and the ability to form bonds with minimum pressure over short open assembly periods.</li> <li>The compounded adhesives offer high cohesive strength derived from reaction with metal oxides.</li> <li>Resonac Chloroprene AF is used in demanding applications such as heat-formed high-pressure laminates and automotive trim attachments.</li></ul>

Resonac Chloroprene 671A

Resonac Chloroprene 671A by Resonac (formerly Showa Denko) is a high solid, anionic, aqueous dispersion of a high-gel chloroprene polymer. It offers a high wet gel strength and medium-slow crystallization rate. It has good storage stability, but pH decreases with time, and the rate depends on temperature and air exposure. The decrease is indicative of structural changes in the polymer and alterations in the colloidal properties of the latex. Resonac Chloroprene 671A is primarily used in dipped goods applications and is suitable for elastomer-based adhesives.
