ASTM International Testing Method:

An international standards organization that develops and publishes voluntary consensus technical standardsfor a wide range of materials, products, systems, and services. HurriBond™ was 3rd party tested to determine compliance with the ASTM C-920, Standard Specifications for Elastomeric Joint Sealants, TYPE S, Grade NS, Class 25, Use; NT, and A.

​

ASTM C-679 (Tack Free Time):

A measurement of surface cure time.

​

ASTM C-794 (Adhesion-in-Peel):

Determines the strength and characteristics of the peel properties of a cured-in-place elastomeric joint sealant, single or multi-component, for use in building construction. The test displays the ability of the cured sealant to maintain a bond to the substrate under severe conditions and it is utilized to help determine the adhesive characteristics of sealant/primer combinations with unusual or proprietary substrates. The sealant passed the testing: 7 Day Water Immersion Test and after 200 hours of UV through glass and 7-day water soak.

​

ASTM C-793 (Effect of Accelerated Weathering)

Provides an indication of how well a properly installed sealant joint will maintain its integrity, and long lasting prevention of air and moisture infiltration without cracking. No cracks after UV exposure, cold weather and bending.
