Kraft Union Paper - Waterproofing | Bitumen
Union Kraft paper can be used where water or wind proofing is required.
Traditional Kraft paper with a bitumen laminated layer which helps form a seal around anything that has penetrated it. Bitumen is a black and oily viscous material that is naturally occurring by-product of decomposing organic material. Often mixed with other materials to form sealants and commonly used as a decorative application on plant pots, it has water-resistant properties and is also known as asphalt or tar.
Kraft Union paper is also commonly used in the wrapping of engineered parts that are oily, due to the water protective nature of the paper. Here at Carters we also have reinforced versions for added strength. Please enquire for more information: 01209 204 777.
