Adhesive and Sealants

MATERIALS

General Information

National Insulation Pty Ltd only uses branded and engineered quality products to deliver excellent coating and adhesion to insulation materials. The products are ideal to fit for applications where a complex combination of materials is used to achieve the performance required in the pipe or vessel material, insulation type and thickness, installation accessories and protective cladding options. Mastics, coatings, and sealants are crucial parts of the insulation system’s last line of defence, protecting it from any number of sources of potential damage.

WATER VAPOR TRANSMISSION

The best way to determine the type of product required to keep water out of a system is to consider the vapor drive for each application.

BREATHER MASTICS

Often referred to as “weather barrier mastics” when used over outdoor insulation surfaces, will allow higher levels of water vapor to pass through their films and will have typical permeance values greater than 1 perm.

VOLATILE ORGANIC CONTENT

Whether it be for air quality purposes or exposure limits, maximum VOC content limits for mastics have been set to ensure low VOCs, while still meeting necessary performance characteristics of the mastics.
