BEST-CA 221 is a one-component, solvent free cyanoacrylate adhesive based on ethyl-cyanoacrylate.
BEST-CA 212 is the standard product for bonding of plastics, e.g. polyamide, PVC, PMMA and various elastomeres, e.g. rubber, EPDM and viton amongst each other and with metals and wood.
BEST-CA 221 is very fast cure. After full cure the adhesive is high strength and temperature resistant.
BEST-CA 221 is ready-to-use and can be applied from the original container.
BEST-CA 221 is applied spot-wise or bead like. Assemble parts by using short, firm pressure. Curing process starts within seconds. On most materials fixture time is reached within 5 to 10 seconds. 85 % of final cure is reached after 30 minutes, 100% after 20 hours. The rate of cure depends on the ambient relative humidity. A relative humidity of 40 to 60% will lead to best results. Lower values may delay cure.
Bonding surfaces must be dry, free of dust and grease as well as other contaminants. Sand-blasting, grinding and staining bonding surfaces will enhance adhesion on bonding surfaces.
CHEMICAL AND ENVIRONMENTAL RESISTANCE
BEST-CA adhesives show good resistance to changing climatic conditions and chemical influences.
