Product description from Rosco:
Rosco FlexBond provides a flexible adhesive bond between many scenic materials, such as fabrics, plastics, foams and wood. It dries to a clear, hard, yet pliable coating that does not suffer from the “tackiness” common in many other flexible glues even after those glues have had days to dry. And unlike ordinary “white” glues which can crack and break when flexed, the adhesive bond of Rosco FlexBond remains extremely pliable and strong even as the materials bend and deform. Rosco FlexBond is water- based with little fume.
Suggested Use: Use FlexBond to adhere fabrics to fabrics, fabrics to wood, foam to wood or fabric and many other combinations of materials common in scene shops. Rosco FlexBond provides an excellent coating over Ethafoam™ that allows this notoriously difficult foam to be painted with ease. With its super adhesion, Rosco FlexBond can be used to laminate blocks of foam together. It can be thinned with water, tinted with colorants or Rosco Paints, or used as an additive to give other coatings like plaster or clay added flexibility.
Application: Apply by brush, roller, or spray gun.
Surface Preparation: Surfaces should be clean, dry and free of dirt and grease. When applying this primer to vinyls or plastics, clean your surface with denatured alcohol to remove any excess plasticiser that might interfere with proper bonding.
Compatibility: FlexBond is compatible with most water-based coatings and is easily painted or tinted. Tint FlexBond using Supersaturated Roscopaint, Off Broadway, latex paint, or colorants. Add the primer to other water-based coatings as an additive to increase flexibility and adhesion.
Mixing: Stir before using. Do not shake as bubbles may develop.
