The suffix LW & CW identifies our Luxo & Celerie Weather-Resistant composite fabrics. Luxo LW & Celerie CW outdoor patterns feature a nanoparticle topcoat called Nano-Pro Tec, which imbues these fabrics with superior resistance to ultraviolet rays, oil and dirt. The Valtekz Nano-Pro Tec coating benefits from extensive research and development work in the field of Nanotechnology. Here, microscopic nanoparticles (one nanometer equals one millionth of a millimeter) are used as building blocks in the formulation of the ultra-weather resistant Nano-Pro Tec top coat of our Luxo LW & Celerie CW composite fabrics. The advantage is that nanoparticles have a lower melting point, they possess a larger total surface area and they absorb light at shorter wave lengths. The result is a composite fabric that is: • Easy to clean • Mildew resistant • Exceeds industry standards for UV resistance • Cold and heat resistant • Resistant to machine oil • Resistant to body care products (suntan lotion) • Flame retardant • Tear resistant • Extremely durable (250,000+ double rubs)
