High quality film is metal primary color no green, because there is no inorganic matter is green in nature, all green is organic matter, so the green car film is inferior dyeing film, a long time will fade,. All the film with color warranty period will not exceed 3 years, it is because of fading, leading to the most important factor of car film fading is ultraviolet light, it will damage the dye and pigment. And on the market a lot of inferior dye film will ultraviolet absorbent is injected only in viscose layer, can block only 30%-40% ultraviolet ray, and this kind of craft stability is poorer, this makes car film can transmute a lot in short time, and this kind of film is torn down to be able to have pungent taste. Our LangShengDi membrane structure layer injected with high-performance ultraviolet absorbent, can block 99% of the ultraviolet light for a long time, effectively prevent CheMo fade, and to provide ten years warranty, if in our stick film, rub off phenomenon, within a decade to give you a new, CheMo bubbles because of the poor quality glue layer on the surface of the coating in CheMo, can't withstand the sunshine illuminate, foaming phenomenon in a colloid oxidation, soon our LangShengDi injected with high performance of membrane structure layer pressure sensitive adhesive of environmental protection, can be cut off for a long time the sun damage, effectively prevent CheMo foaming, and provide 10 years warranty, if in our the membrane, If there is blister, I will replace it with a new one within 10 years.
