This research aims to know the quality of the various production centers gambier in West Sumatra and the main constituent component(tannins and catechins) in relationships with the bonding strength of adhesive gambier. This research using an exploratory method with three replications. Sampling took from five production centers in West Sumatra namely in the Lima Puluh Kota District covering Muaro Paiti, Pangkalan, and Sago Halaban. While in the Pesisir Selatan District include Batang Kapeh and Siguntur. The sampling method is done randomly by taking Gambier at the place of production of one of the Nagari. The results showed a strong relationship between the high content of tannin Gambier with adhesive strength is generated in the amount of R2= 0,9032. The higher tannin content of, the adhesion force is generated will be higher, otherwise higher content of catechins which causes the lower adhesion strength. The best adhesion strength was Sago Halaban with the adhesive strength of 21.1 kg/cm2, tannin content of 30.55%, catechin content of 44.47%. The adhesive quality produced from Gambier suitable the SNI 06-4565-1998,SII 0778-83 Adhesive Phenol Formaldehyde Liquid standards and suitable with Japanese Industrial Standart (JIS A 5908;2003)
