Tank Linings: How to Protect Against Corrosion
The 3-D glass material is laid down in parallel courses with edges buttedtogether however not overlapping. After each parallel course is rolled out, aspecially-designed seam materials known as PHONIX TAPE is applied, uniformlywetted, and rolled out over the butted seams of the 3-D glass material. Thismaterial is required to seal off the joints of the 3-D glass cloth, creating ahomogeneous 3D-lining. Additional epoxy is sprayed on this first layer asrequired, to make sure proper wet-out.
