Abstract
Disclosed are compositions that can be used in forming products with increased near infrared (IR) reflective capability. A composition can include IR reflective and/or IR transmissive non-white pigments and can be formed with suitable viscosity so as to successfully coat substrates, e.g., yarns, suitable for use in forming coverings for architectural openings, e.g., window coverings. Also disclosed are textile substrates coated with the compositions, including textile substrates coated with compositions that include abrasive, inorganic IR reflective dark pigments.
Claims26
A covering for an architectural opening comprising:
- a cured polymeric composition comprising a polymeric resin and a non-white pigment, the pigment being an infrared reflective pigment or an infrared transparent pigment, the cured polymeric composition having a CIELAB L* value of less than about 90 measured at an observation angle of 25°, the covering reflecting more than about 15% of impinging solar radiation between about 700 and about 2500 nm.
A composition for coating a component of an architectural opening, the composition comprising:
- a polymeric resin;
- and
- a non-white pigment, the pigment being an infrared reflective pigment or an infrared transparent pigment;
- wherein
- the composition has a viscosity of less than about 5000 cP as measured with a Brookfield RTV at 20 rpm, and the cured composition has a CIELAB L* value of less than about 90 measured at an observation angle of 25°.
