The Relationship Between Resin Solids Content and Cured Strength of Two Cold-Setting Laminating Adhesives

摘要

The results of performance tests and adhesive strength tests of two cold-setting laminate adhesives are presented. The commercial wattle-tannin adhesive satisfies all the weather and boil proof requirements of the British standard specification BS 1204 in a percentage resin solids content range of 43% to 59%, and of the South African Bureau of Standards draft specification for exterior wood adhesives in a range of 53% to 59% resin solids content. The commercial phenol/resorcinol/formaldehyde adhesive satisfies all the weather and boil proof requirements of the British standard specification BS 1204 in a percentage resin solids content range of 42% to 54%, and of the South African Bureau of Standards draft specification for exterior wood adhesives at 52% and 54% resin solids content.
