BOSS®614 Foam Release is a professional grade silicone lubricant designed to prevent spray foam from sticking to treated surfaces. Our proprietary formulation of silicone, propellants, and fast-evaporating solvents allows for a fine-mist spray pattern and even distribution which prevents spray foam from sticking to treated surfaces. BOSS®614 is a dry-film lubricant highly effective for waterproofing and corrosion prevention. BOSS®614 is suitable for metal, plastic rubber, vinyl, leather, wood, and polycarbonate respirator face shields.
