The OB1® Hybrid Sealant & Adhesive features a hybrid polymer formula that is user-friendly. It serves as a versatile substitute for mastics, wood and PU adhesives, silicones, acrylics, and butyl rubber sealants. Due to the lack of solvents, it will never shrink or crack. This product can be applied on wet surfaces, painted or molded, with an exceptionally high bonding strength and resistance to fungal and bacterial growth.
