Denka Liquid Dispersion Neoprene

Introduction

Denka™ Neoprene liquid dispersions are aqueous, colloidal dispersions of polychloroprene or copolymers of chloroprene and other monomers such as sulfur,
2,3-dichloro-1,3-butadiene. These LD products are available only as anionic surfactant systems.

Use

Neoprene liquid dispersions are designed to have different polymeric and colloidal properties to serve a variety of applications:

Adhesives – pressure sensitive, heat or solvent activated for laminating and contact bond,
Binders – as saturants and wet-end additives for fibrous products such as paper, nonwovens, bonded batts, and for aggregates in resilient surfacing,
Coatings – industrial and decorative,
Dipped Goods – supported and unsupported films,
Elasticized asphalt and concrete, and
Foam.

All Neoprene liquid dispersions are suitable in any of the following general categories. Due to various characteristics, a type of Neoprene liquid dispersion may
be preferred over another, depending on the application. The table below is a general guide that indicates LD types most suitable for the various applications.

Liquid Dispersions

Liquid Dispersions
GRADE	Solids Content, %	Crystallization	Features
571	50	Moderate	High tensile strength
671A	59	Moderate	High-solids, General purpose
750	50	Very Slow	Excellent flexibility
842A	50	Moderate	Fast curing, Low modulus

Characteristics

Polymer characteristics, including crystallization rate, molecular structure, and chemical composition, can be modified primarily through the use of co-monomers.
Selection of the best type of Neoprene liquid dispersion for a particular application is done by considering how differences in polymer characteristics affect the end
use of the application.

The table below provides a qualitative comparison of the important properties of the four types of Denka™ Neoprene liquid dispersion.
