FulaPrene 303™ is a neoprene based adhesive sealant ideal for use in sealing lap joints in sheet metalwork. FulaPrene 303™ will adhere to a wide range of substrates and can be used in numerous common construction applications.
Not recommended for: permanent water immersion. Wide or moving joints. Solvent sensitive materials.
All surfaces must be clean, dry, sound and free of dust, oil, old sealant or other contamination. For best results wipe all surfaces with isopropyl alcohol (IPA) using a lint free cloth. Adhesion to metals can be further improved by light abrasion.
Application: Mask either side of joint to produce a neat finish. Cut tip off cartridge and trim nozzle to suitable size. Attach nozzle onto cartridge and place in H.B. Fuller caulking gun.
Gently squeeze trigger to dispense and push sealant into joint ahead of nozzle to ensure complete filling. Within 5 minutes of application, finish surface with wetted spatula or other smooth implement.
