STUDY OF PIGMENTS ON PVC ARTIFICIAL LEATHER CLOTHS

Abstract

The formulation of IR-reflective coatings for various applications depends on many factors, some of which cannot be seen with the naked eye. There are two main keys to formulating these coatings. 1. Individual pigment selection: Select IR-reflective pigments. 2. Milling and dispersing: Do not over grind and degrade IR properties. 3. Mixing IR-reflective pigments: Be aware of the invisible interactions of different pigment types in the IR region. 4. Opacity: Use an IR-reflective substrate/primer if possible, or manage the pigmentto- binder and film thickness to minimize effect of absorptive substrates. 5. Contamination: Inclusion of even small amounts of IR-absorbing pigments can greatly reduce TSR. The second key is to work with a partner with the products, research, and most importantly, technical support to allow you to formulate, test and validate your IRreflective coatings. The IR range is invisible to the human eye, not covered by standard spectrophotometers, and measurable only by expensive and specialized equipment. A partner who can shepherd you in pigment selection, color matching and testing, along with guidance in the different regulations and programs can be an invaluable aid in formulating, marketing and supporting differentiated IR-reflective coatings.
