Anti-ultraviolet finishing agent SCJ-966Ⅱ
Ultraviolet rays in the solar spectrum not only fade and embrittle textiles, but also cause sunburn and aging of human skin, producing melanin and stains, and even more serious, it can induce cancer and endanger human health. The protection principle of SCJ-966Ⅱ anti-ultraviolet fabric is that SCJ-966Ⅱ absorbs high-energy ultraviolet rays, converts it to low energy through the jump of molecular energy level, and turns it into low-energy heat or electromagnetic waves with shorter wavelengths, thereby reducing the intensity of sunlight. , To eliminate the harm of ultraviolet rays to the human body and fabrics; at the same time, SCJ-966Ⅱ can also increase the reflection and scattering of ultraviolet rays from the fabric, and prevent ultraviolet rays from penetrating the fabric.
 
Beijing Jiershuang High-Tech Company is a manufacturer of anti-ultraviolet finishing agent. The anti-ultraviolet AU-100 anti-ultraviolet finishing agent has been put on the market in large quantities for 20 years. JLSUN® anti-ultraviolet finishing fabric meets the Chinese standard "GB/T18830-2009 Evaluation of Textile Anti-ultraviolet Performance", Australian/New Zealand standard AS/NZS 4399:1996, European Union standard EN13758-1:2001 and EN13758-2:2003, American AATCC183 -2004, ASTMD 6544 and ASTMD 6603, British Standards BS8466-2006, BS7914-1998 and BS7949-1999, International Certification Association Standard UV Standard 801 and other domestic and foreign standards. Jiershuang laboratory provides customers with free testing of the anti-ultraviolet effect of fabric.
 
Product traits and technical indicators
 
anti-ultraviolet finishing agent SCJ-966Ⅱ mainly contains high-efficiency ultraviolet absorbing materials, products treated with SCJ-966Ⅱ, will not affect the color, strength and moisture permeability of the fabric. SCJ-966 is a pale yellow liquid with an active ingredient content of more than 33%, a PH value of about 7, ionicity is non-ionic, and miscible with organic solvents. Anti-ultraviolet finishing agent SCJ-966Ⅱ is suitable for solvent coating, artificial leather, PVC calendering, plastic products, polypropylene, polyester and nylon fibers, etc. It is good for ultraviolet rays in the 180-400nm band (especially UV-A and UV-B) The absorption conversion, reflection and scattering effects of Authoritative organization test proves: The UPF value of JLSUN® SCJ-966Ⅱ coating finishing cloth is as high as 50+, and the UPF value is still 50+ after 40 washings.
 
  Instructions for use
 
SCJ-966 can be used for coating, padding, spraying, rolling, etc. The dosage is usually 2-3% o.w.f., and the specific dosage and usage depends on the variety and purpose. The coating process is as follows:
 

  1. Craft prescription:
 
Anti-ultraviolet finishing agent SCJ-966 2-4%
 
Solvent-based coating paste X%
 
Organic solvent Y%
 

  2. Process flow: bleached and dyed fabric→coating→drying→finished product
 
Packaging and storage: 25Kg plastic bucket packaging. Stored in a cool warehouse above 0℃, the storage period is 12 months.
