SPRI Releases Field Test Method for Low Rise Foam Adhesives
WALTHAM, Mass. — SPRI has released a field test method for bond strength of low-rise foam adhesives to existing roof substrates. Requests for field adhesion tests — especially for fleece-back membranes — have become more prevalent. SPRI is answering this industry need by providing technical guidance that will standardize the test procedure. SPRI represents sheet membrane and component suppliers to the commercial roofing industry.
The field test method is an addendum toANSI/SPRI IA-1, Standard Field Test Procedure for Determining the Mechanical Uplift Resistance of Insulation Adhesives over Various Substrates. Taking into consideration that roof membrane manufacturers have tested their membranes and have known values, the pull test procedure will focus specifically on the adhesion of the adhesive to specific roof substrates and monolithic decks using low-rise foam adhesives.
