SL resin 50 CF (Cavity Filling) is a structural two-component polyurethane foam system, designed for undersealing and void filling under concrete slab sections. The slow speed reactivity profile allows for excellent flow characteristics when used as an undersealing and void fill material. It will run and level itself and expand slowly with low heat.

Properties & Application

RESIN 50 CF is a polyol formulation which, mixed in the appropriate ratio with Resin 50 CF hardener, generates an expandable foam with a free rise density between 35 and 45 kg/m', depending on the volume mix ratio. It's engineered to flow throughout intricate cavities to fill the entire void to add structural support, prevent vibrations, deaden sound and increase insulation value. Ideal for filling blind and intricate cavities.

Safety & Precautions

To avoid extensive reaction or scorching, make sure that the component temperature does not go above 40°C and avoid filling large cavities in one application. High temperature formulation with slower reaction and low scorch is available on request. Protect your health! Working with this material, safety goggles, gloves and safety clothing should be worn at all times. While injecting, a full face shield is strongly recommended. Spills and blowouts do happen! Protect yourself and others on the jobsite. Consider covering property in proximity of the application area to prevent loss or damage. Protect your jobsite from unauthorized persons, Store all materials and equipment safely and out of reach of children! Observe container labels, MSDS, and instructions in the Product catalogue before using the product and equipment. In case one of the components comes in contact with the skin, wash thoroughly with soap and water. Provide adequate ventilation in volume and pattern in working area. Further protection: emergency showers and eyewash stations


Storage temperature: 5°C - 30°C. Shelf life: 12 months. Store the material in its original packaging to prevent moisture ingress in a dry well-ventilated area not exposed to direct sunlight and in compliance with local safety requirements

How To Use it

RES1N 50 CF should only be used in combination with RESIN 50 CF hardener, using a two-component volume pump and correct mixing ratio. The component temperature should not exceed 40°C.
