FDP629 is primarily a foam compression sealant. The soft foam is predominantly closed cell, with an acrylic pressure sensitive adhesive coated on one side, and a removable paper release liner on the other non-adhesive face reducing dimensional change during application. This product displays good resistance to dilute acids and alkalis, and very good UV light resistance. With resistance to abrasion, corrosion and moisture, FDP629 is suitable for both indoor and outdoor environments. FDP629 will act as a water seal and air/dust seal when compressed. Minimum 30% compression required to effect a water seal. Applications include for preventing electrolytic corrosion, for cushioning, forms a compression water seal, forms a compression air/dust seal, for gap filling of irregular surfaces, for anti slip mounting.
