KCL 시험성적서

Some of my customers suffer from asthma and always ask whether there are chemicals either in the application solution or the film itself that will affect their condition. What shall I tell them?

Answer: After installation, there should be no problem at all with any "chemical emission" from the film which will affect asthma patients. We base this claim on 1) the utter absence of data to the contrary, 2) on the basis of the chemical stability of the film and SR coating themselves, and 3) the prevalence of polyester & acrylic products in our environment.

Literally millions of installations around the world have taken place over a span of more than twenty to thirty years with no reports indicating any connection between the existence of film on windows and the worsening of an asthmatic condition in anyone. We do know, however, the X-100 can be a mild irritant if directly inhaled (whether one is asthmatic or not), since it contains a very mild solution of phosphoric acid. We recommend more of a coarse "stream-like" setting on the spray head of the bottle or tank to minimize aerosolizing of the application solution, or the use of Film-On when working in homes/offices of asthmatic persons. (One might suggest to asthmatics that they temporarily leave the area during the installation, if X-100 is the preferred application solution.) Film-On, for asthma patients, should prove far less likely to be an irritant during installation since it has a neutral ph. If someone claims to be allergic, or has an asthmatic response, to baby shampoo, the most probable culprits would be the additives used. Film-On is essentially baby shampoo stripped of all these additives: lanolin, glycerin, silicone, perfume, dyes, etc. No substantiated claims, to our knowledge, have ever been made regarding Film-On as an irritant to asthmatic patients.

Finally, regarding polyester film and acrylic hardcoatings generally, polyester is used very widely in the packaging industry, such as in film form to wrap foodstuffs (candies, biscuits, etc.) or molded form (bottles, boxes, etc.). There are far more polyester-based products around in the world than window film. Asthmatics will therefore come into contact with polyester virtually every day of their lives, at least in developed countries such as the USA, UK, etc. Similarly, acrylic materials are all around us, such as in plastic glazing, shower basins and spectacle lenses, and similar comments apply. Polyester in the film and acrylic in the SR coating are therefore safe. "Safe" does not mean "no risk;" in this case it means "very low risk."

Additional Notes on Quantitative and Qualitative Testing of LLumar SCL SR PS4 safety film to fire safety tests 4R-E207 Issue 4 and 4R-208 Issue 4:

The toxic fume emission requirements for London Underground are given in LUL Engineering Standard E 1042 A6, Attachment 2, Section 3, which details the chemical composition with respect toxic fumes emissions. This Section also states that materials used within London Underground shall not contain chemical elements that could produce significant quantities of toxic combustion fumes, especially organically bound halogens, nitrogen, sulphur of phosphorus. Trace level are permitted; ‘trace level’ means that the weight for weight for weight percentage of the chemical group, divided by the atomic weight for that group, shall not exceed 0.015%.

The above Quantitative Analysis therefore produces the following figures:

LUL 엔지니어링 기준 E 1042 A6, 첨부 2, 섹션 3 에서 주어진 런던 지하철의 독성 연기방출 요건은 독성 연기 방출에 대한 화학 물질의 구성을 설명하고 있습니다. 또한 이 섹션에서는 런던 지하철 내에서 사용되는 물질은 상당한 양의 독성 연소를 일으킬 수 있는 화학 물질이 포함되면 안 된다는 것을 기술하고 있고, 특히 유기적으로 결합된 할로겐, 질소, 황 또는 인 등이 해당됩니다. “추적 수준”은 화학물질 군의 무게 백분율의 중량을 원소의 무게로 나눈 것이며 0.015%를 넘지 않아야 됩니다.

위의 양적 분석은 다음의 수치를 산출합니다.
