We cannot accept your deduction $1,775 as we don’t admit the material has any problem.The swatch you sent us as defective swatch didn’t have any problem.If you are saying it’s different with sample material, than please send it to us too, we would check and reply. 2. We didn’t say we don’t want to do the light transmittance test, but you didn’t let us know how to proceed that test.How can we test it while we don’t know how did you test?Like I said before, we need to know your working condition and test method
