Properties:Clariant Sanduvor PR-31 or Hostavin PR-31 equivalent; it’s a hindered amine light stabilizers with UV absorption properties.it can be used as a light stabilizer for plastics(polyolefins,polystyrene,PVC,PBT and many engineering plastics),paints and coatings etc.
Application:
YCPS628 represents a sophisticated combination of HALS functionality with UV absorption functionality.Depending on the way of exploitation(light exposure conditions,type of polymer matrix),YCPS628 molecules can undergo a photochemical reaction and become chemically grafted to polymers.thereby a highly persistent,non-extractable stabilizer is formed which gives an excellent long term protection to the polymer;
YCPS628 has great synergism effect with other UV absorbers,antioxidants and hindered amine stabilizers;
YCPS628 can be used in polypropylene, polyethylene, polystyrene, polyvinyl chloride, ABS,epoxy resin,polyester resin such as films,sheets,fibers;
YCPS628 has great color stability.so it has good performance in colored request products such as coatings,paints,adhesives and suitable for outdoor seats and automotive bumpers for long term outside exposure;
light stabilizers can withstand chemical extraction
recommended dosage: 0.3%
Package and Storage:
25kgs/bag or drum it is not a dangerous product according to transportation regulation
